Ep 6: Rent vs Flip: How to Decide Your Next Iowa Deal

Rent vs Flip: How to Decide Your Next Iowa Deal -- August 18, 2026

 

[NEIL] Picture two houses. Same block, same price, same rehab budget.

[NEIL] One of them made me twenty-eight thousand dollars in six months.

[MAGGIE] And the other one?

[NEIL] The other one is still making me money every single month, and it didn't cost me a dime more to get there.

[MAGGIE] Same house. Two totally different outcomes. That's what we're breaking down today.

 

[MAGGIE] Welcome back to Flipping Iowa. I'm Maggie Monroe.

[NEIL] And I'm Neil Timmins.

[MAGGIE] I spent this week inside a blog post on littleguyloans.com about a question I hear from investors constantly, and it's not, should I flip this house. It's, should I flip this house, or should I keep it?

[NEIL] Rent versus flip. It's the one decision that trips up more investors than almost anything else I see, because most people decide with their gut instead of a spreadsheet.

[MAGGIE] And you don't decide with your gut?

[NEIL] Never. I run every property through the same two sets of numbers before I touch a dollar of it. Today we're walking through exactly how I do that.

[MAGGIE] Including a duplex that flipped your own instinct upside down, but let's start with the basics. Set the scene for me. Somebody's got a property under contract, or close to it. When does this rent versus flip question actually come up?

[NEIL] It comes up the second you see the number on the flip side and it's not big enough to feel exciting. That's the moment. Most investors' first instinct is to assume that means the deal is dead.

[MAGGIE] But it's not dead, it's just a different kind of deal?

[NEIL] Right. A thin flip margin doesn't mean walk away. It means run the second set of numbers, because sometimes the same exact house is a mediocre flip and a genuinely strong rental.

[MAGGIE] Why do people skip that step? Why not just run both from the start?

[NEIL] Because flipping and renting solve two completely different problems, and most investors have only trained themselves to think in one of them. A flip is one lump sum, paid once, on the spread between what you paid and what a buyer pays you. A rental is a long, slow stack of smaller wins, month over month, year over year.

[MAGGIE] So you can't compare a one-time number to a monthly number and call it a fair fight?

[NEIL] Exactly. You have to convert both into the same unit before the comparison means anything. I run both as an annualized return on the actual cash I've got sitting in the deal. Once you've done that, the comparison is honest.

[MAGGIE] Give me an example of somebody getting this wrong.

[NEIL] Sure. I had an investor a while back who ran the flip numbers, saw a projected profit of thirty-five thousand dollars, and grabbed it without ever running the rental side. Six months later the market had shifted, days on market stretched out, and that thirty-five thousand shrank to about eighteen thousand after the extra holding costs. If he'd run the rental numbers first, he'd have seen a property that could have cash-flowed four hundred dollars a month indefinitely, which on an annualized basis actually beat what he ended up clearing on the flip.

[MAGGIE] So skipping the second calculation cost him real money, not just theoretical money?

[NEIL] Real money. That's the whole reason I force myself to run both, every single time, no exceptions. It takes an extra twenty minutes. It's saved me from bad decisions more times than I can count.

[MAGGIE] Twenty minutes seems like a small price for that kind of insurance.

[NEIL] It is, and most people skip it anyway, because running the flip numbers feels like the whole job. You get a number, it looks decent, and the instinct is to move. Running a second, completely different set of numbers on the same property feels redundant in the moment, even though it almost never is.

[MAGGIE] Okay. Walk me through it. Where do you start?

[NEIL] I always start with the flip math first, even if I think I'm going to end up holding the property. The flip number tells me the ceiling. It tells me the most I can pay.

[MAGGIE] So even a hold decision starts with a flip calculation?

[NEIL] Every time. First I pull comps for the after repair value. Three to five homes that actually sold recently, fully renovated, in the same pocket of the metro. Not active listings, not a house two miles away in a different school district just because the square footage matches.

[MAGGIE] People fudge that part, don't they?

[NEIL] Constantly. A stretched comp is how a flipper talks themselves into a bad number. Second, I price the rehab scope room by room, real line items, plus a contingency for what I can't see yet behind the walls. Third, I apply the seventy percent rule. Purchase price plus rehab needs to land at or under seventy percent of the after repair value.

[MAGGIE] That seventy percent number, is that just your rule, or is that industry standard?

[NEIL] It's close to industry standard, and it's also baked into how I lend. On a qualifying Iowa deal I'll fund up to ninety percent of the purchase price, up to one hundred percent of the rehab, but the after repair value cap is what controls the whole loan. Maximum seventy percent of that after repair value. That's the ceiling no matter how the other numbers shake out.

[MAGGIE] So the same seventy percent rule that tells you if it's a good flip is also the number that decides how much I can actually borrow?

[NEIL] Same number, doing two jobs.

[MAGGIE] And how fast can you actually move once someone decides?

[NEIL] Once the numbers work, I can approve a qualifying deal in twenty-four hours and close in five days. That speed matters whether you're planning to flip it or refinance it into a rental, because the clock on your holding costs starts the day you close, not the day you decide.

[MAGGIE] Okay, back to the checklist. What's fourth?

[NEIL] Fourth, I subtract everything holding and selling the property is going to cost me. Interest, insurance, utilities, a real estate commission when it sells. Whatever's left after all of that, divided by the months I'm in the deal, is my flip return per month.

[MAGGIE] And that's the ceiling number you compare the rental against?

[NEIL] That's it exactly.

[MAGGIE] Okay, now walk me through the rental side, because I think that's where people get lost. It's not one number.

[NEIL] It's four, and they all have to work together. First, monthly cash flow. Rent, minus the mortgage, taxes, insurance, a maintenance reserve, a vacancy reserve, and property management if you're using it. Second, the cap rate, which is the net operating income divided by the purchase price. That's your return if you paid all cash.

[MAGGIE] Which almost nobody does.

[NEIL] Almost nobody, which is why the third number matters more in practice. Cash-on-cash return. Take the annual cash flow and divide it by the actual cash you put into the deal. If you financed most of it, that's the number that tells you the truth.

[MAGGIE] And the fourth?

[NEIL] Appreciation and loan paydown. Slower, less certain year to year, but it's real value building in the background the entire time you hold the property, whether you're watching it happen or not.

[MAGGIE] So a property that just barely breaks even on monthly cash flow, that's not automatically a bad rental?

[NEIL] Not at all. Add five or ten years of appreciation and paydown on top of a break-even cash flow and you can end up way ahead of where the flip would have landed you. A rental that loses money every single month, that's a different story. That one rarely gets there.

[MAGGIE] Can you make that real for me? Walk me through an actual property.

[NEIL] Take a three-bedroom ranch in Ankeny, a place I looked at back in the spring. A hundred ninety thousand dollar purchase, twenty-five thousand in rehab, so two hundred fifteen thousand all in. Rents at seventeen hundred a month in that pocket of Ankeny right now.

[MAGGIE] So run the cap rate on that one.

[NEIL] After taxes, insurance, and a six percent maintenance and vacancy reserve, net operating income comes out around fourteen thousand four hundred a year. Divide that by the two hundred fifteen thousand purchase and rehab, and you're looking at a cap rate just under seven percent.

[MAGGIE] And the cash-on-cash number, since almost nobody's paying all cash?

[NEIL] Right, say you financed most of it and you've only got fifty thousand of your own cash actually in the deal after the loan. After the mortgage payment on top of everything else, monthly cash flow lands around three hundred dollars. That's thirty-six hundred a year, divided by that fifty thousand in actual cash, and you're at about seven percent cash-on-cash. Add in maybe three or four percent a year in paydown and appreciation, and you're looking at a real annualized return closer to ten or eleven percent, every year, for as long as you hold it.

[MAGGIE] Versus a flip that might hand you a bigger check once, but only once?

[NEIL] That's the trade. A flip might return fifteen or twenty percent on a single deal, but it's a single event. The rental compounds every year you keep it. Neither one is automatically the right answer, that's the whole reason you run both.

[MAGGIE] So where does the Des Moines market itself come into this? You said the math is universal, but something local is tipping the scale right now.

[NEIL] A few things. Rehab costs across the Des Moines metro have stayed a lot more predictable than what you'd see in a coastal market, which protects your flip margin as long as you underwrote it conservatively to begin with. Rental demand out in Ankeny, Urbandale, Waukee has held steady, because home prices are keeping first-time buyers renting longer than they used to. That supports the cash flow side.

[MAGGIE] And the piece that's working against the flip side right now?

[NEIL] Days on market. For renovated flips in the core metro neighborhoods, it's crept up compared to two years ago. And that one number changes the whole equation faster than people realize.

[MAGGIE] Say more about that, because I don't think people connect days on market to their actual decision.

[NEIL] It's the single biggest signal I watch on any flip, and most investors don't track it at the level of detail that actually makes it useful. If a property's going to list at two hundred fifty thousand, I'm not looking at all of Des Moines. I'm looking at non-new construction in that two hundred to three hundred thousand dollar range, because that's the competitive set the house actually gets measured against. Then I narrow it again to the specific suburb, sometimes the specific zip code.

[MAGGIE] So it's not a citywide number, it's hyper local?

[NEIL] Has to be. And it's not a snapshot, it's a trend. Is the number compressing, meaning houses are moving faster than three months ago? Or is it expanding, meaning inventory's building and buyers are taking their time? That direction matters as much as the number itself.

[MAGGIE] And every extra day on the market is a day of holding costs?

[NEIL] Interest running, taxes accruing, insurance billing, every single day. A project in a fifteen-day market has a completely different cost structure than the identical project in a sixty-day market. If you don't bake that into the underwriting before you ever swing a hammer, you find out the hard way when the house is just sitting there.

[MAGGIE] You've said before there's a second piece to that, something about how many deals you can even do in a year?

[NEIL] Capital velocity. None of us have unlimited money to work with. How many deals you can do in a year comes down to how fast each one turns. If your average flip takes six months start to finish, you get two of them per capital cycle. Compress that to four months, now you're getting three. Days on market is a real chunk of that equation. It's not a vanity number. It's a budget input, a risk signal, and it decides how many projects you can realistically run in twelve months.

[MAGGIE] So when days on market is stretching in a given submarket, that's exactly the moment the rental side of the comparison starts looking better?

[NEIL] That's precisely the moment. A thin flip margin gets thinner every extra week a house sits. A rental doesn't care how long it takes to lease up once, it just needs a tenant, and then it's producing every month after that.

[MAGGIE] Does that same math hold up the same way in every part of the metro, or does it shift neighborhood to neighborhood?

[NEIL] It shifts constantly. Beaverdale and South of Grand carry higher price points, so the flip margins can be bigger in dollars, but rents haven't kept pace with those purchase prices, so the cap rates run thinner if you hold. Out in Ankeny and Waukee, purchase prices are lower relative to rent, so the rental math tends to pencil better, even though the flip upside per deal is usually smaller.

[MAGGIE] So the same decision framework, different answer depending on the zip code?

[NEIL] Same framework, different answer every time. That's why I tell people not to memorize a rule of thumb. Rerun the numbers on every single property, in whatever neighborhood it's actually in.

 

[MAGGIE] You mentioned a duplex that changed your own mind. Tell me about it.

[NEIL] Beaverdale, earlier this year. Two hundred twenty thousand dollar purchase, needed about forty thousand in rehab. Comps on similar duplexes nearby put the after repair value around three hundred forty thousand.

[MAGGIE] Run the flip number for me first.

[NEIL] Purchase plus rehab is two hundred sixty thousand, which is seventy-six percent of the after repair value. Already over my seventy percent ceiling before I even factor in holding costs. After six months of interest, insurance, and a realtor's commission on the sale, the projected profit dropped to around twenty-eight thousand dollars. Divide that by six months in the deal, and you're under five thousand dollars a month against the capital tied up.

[MAGGIE] Not nothing, but not exciting either.

[NEIL] Not for the risk of a slower sale season on a margin that thin. So I ran it as a rental instead. Two renovated units at fourteen hundred fifty dollars each, that's twenty-nine hundred dollars a month coming in. After the mortgage, taxes, insurance, and reserves, it penciled to about six hundred fifty dollars a month in cash flow.

[MAGGIE] On top of the paydown and appreciation?

[NEIL] On top of all of that, and on a smaller cash outlay too, because I refinanced most of the rehab into a long-term loan once the work was done. Annualized, the rental beat the flip on that specific property. Not because the flip was a bad deal. Because the margin was too thin to justify the risk on a sale that might take longer than I wanted.

[MAGGIE] Would that same math have worked a year earlier, when days on market was faster?

[NEIL] Probably not the same way. A year earlier that flip margin might have carried the risk just fine, because a faster-moving market shrinks your holding cost exposure. That's the whole point. Run your own numbers on your own property, in the market conditions you're actually in right now. Don't copy my conclusion off a duplex you've never seen.

[MAGGIE] When you refinanced out of the short-term loan, what did that process actually look like?

[NEIL] Once the rehab was done and I had a signed lease, I moved it into a long-term rental loan underwritten on the debt service coverage ratio, meaning the lender cared whether the rental income covered the new payment, not my personal income. That's a different underwriting conversation than the purchase loan, and it's worth understanding before you're standing in the middle of it.

[MAGGIE] So the exit plan has two stages, the short-term money that gets you through the rehab, and then the long-term loan that lets you actually hold it?

[NEIL] Exactly right. Plan for both from day one, not just the first one.

 

[MAGGIE] I know exactly what somebody's thinking right now. I don't want to become a landlord. I don't want the three a.m. phone call about a water heater.

[NEIL] That's the most common objection I hear, and it's a fair one. Being a landlord is a real job, even with a good rental. But I'd push back on the framing a little. You don't have to hold every property forever. You can run this decision property by property, deal by deal, and still flip most of what you buy.

[MAGGIE] So it's not an all-or-nothing identity, flipper or landlord?

[NEIL] It's not. Some investors run one or two rentals alongside a steady flip business specifically because it smooths out a slow sale season, exactly like the Beaverdale duplex would have done for me this year. The rental isn't replacing the flip business. It's a release valve for the deals where the flip math doesn't quite pencil.

[MAGGIE] What about someone who says the numbers are close enough that it's basically a coin flip? How do you tiebreak that?

[NEIL] I look at what I actually want my next twelve months to look like. If I need the capital back out to do my next three deals, I lean flip, because that cash coming back fast is worth something the spreadsheet doesn't fully capture. If I've got capital that can sit and I want one more stream of monthly income on the books, I lean rental. The math gets you close. Your own capital position and your own goals make the final call.

[MAGGIE] What about someone worried that by the time they're ready to refinance into a long-term rental loan, rates have moved against them?

[NEIL] That's a real risk, and I tell people to underwrite the refinance conservatively from day one, not to assume today's rate. Run the rental cash flow at a rate a point or two higher than what you'd actually qualify for right now. If the numbers still work at that higher rate, you've got margin. If they only work at today's rate, that's not a rental, that's a bet on the Fed.

[MAGGIE] So build the cushion into the numbers instead of hoping the market cooperates?

[NEIL] Every time. Hope isn't a financing strategy.

[MAGGIE] Any other objection you hear a lot on this one?

[NEIL] The management question. People worry about finding a good property manager, or worry about self-managing on top of everything else they've got going. Fair concern, but it's a solvable one. A well-run property manager in this metro typically runs eight to ten percent of collected rent, and I bake that straight into the cash flow number before I ever decide rent versus flip. If the deal only cash-flows because you assumed free labor managing it yourself, that's not a real number.

[MAGGIE] So build the management cost in from the start, the same way you build in the rate cushion.

[NEIL] Exactly the same principle. Underwrite it like the worst version of yourself is running it, not the most optimistic version. If it still works, you've got a real deal.

[MAGGIE] That's a more honest answer than, just run the numbers.

[NEIL] The numbers get you ninety percent of the way there. The other ten percent is knowing what you actually want out of the next year.

 

[MAGGIE] Before we wrap, we like to close every episode with a piece of Iowa history, and today's ties in closer to this topic than usual.

[NEIL] It does. Franklin Roosevelt signed the Social Security Act back on August fourteenth, nineteen thirty-five. But here's the detail people don't know. The payroll tax underneath it didn't actually start until nineteen thirty-seven, and it started as a flat one percent, on the employer and on the employee both.

[MAGGIE] One percent, that's it?

[NEIL] That's it. Nobody called it permanent at the time. It was pitched as a modest little safety net, bolted onto paychecks that were already stretched thin from the Depression. Nobody in nineteen thirty-seven thought that line was going to still be there generations later.

[MAGGIE] And it still is, every single check?

[NEIL] Every check you cut for a crew, whether you think about it or not. And that's the same lesson as everything we just talked about. A small monthly number, cash flow of six hundred fifty dollars, a one percent payroll line, doesn't look like much the day you set it up. It's what it turns into over years that actually matters. That's the whole case for the rental side of this conversation.

[MAGGIE] I love when the history actually pays off the episode instead of just being trivia.

 

[NEIL] So here's what I want you walking away with. Run the flip numbers first, because that tells you your ceiling. Then run the four rental numbers, cash flow, cap rate, cash-on-cash, and appreciation with paydown, on the same annualized basis so the comparison is actually fair.

[MAGGIE] And watch days on market in your specific submarket, because that's the number that can quietly turn a solid flip into a better rental.

[NEIL] The property never tells you which path to take. The math does. Run both sets before you write an offer, every time.

[MAGGIE] If you got something out of this one, share it with a friend, and be sure to subscribe so you don't miss the next one. Catch you on the next episode.

[NEIL] Talk soon.
