Do you underwrite the gut so it can become a rental, or is that just a nicer word for a bad flip

Question

The exit-flexibility argument goes like this: if you underwrite a full gut so that the finished house also works as a rental at your all-in basis, then a soft resale market can't force you into a fire sale. You refinance, place a tenant, and wait it out. That flexibility gets described as risk management and I understand why.

The counterargument I keep running into from people who've actually done heavy rehabs is that the requirement strangles your deal flow, and worse, it makes you finish the house wrong. A rental finish and a resale finish aren't the same house. Different flooring, different appliance tier, plus different decisions about whether that third bedroom needs a closet system. If you build for both you build for neither, and you spend 15k on finishes a tenant will destroy and a buyer would have paid 30k for.

Then there's the basis problem. On a gut, your all-in is high by definition, and a house that pencils as a rental at a full-gut basis in most markets I look at is a house where the ARV was never enough to flip in the first place. So the deals that pass the dual test are a small and strange set.

I'm building a list, not buying yet, so I'd rather learn this from people who've had to make the call under pressure. If your gut stalled on market and you flipped to a hold, did the numbers actually work, or did you just stop the bleeding?

The finish argument is weaker than it sounds and the basis argument is stronger.

On finish: I've held two guts that were built to sell and the delta was smaller than people claim. I swapped the flooring spec on one of them mid-job when the market went quiet, cost me about 2,800 and a week. Appliances I left alone and the tenant hasn't destroyed them in three years. What you can't retrofit is layout, and layout decisions that sell also mostly rent fine. Open kitchen, two full baths, closets. Nobody has ever declined to rent a house because the kitchen island was nicer than it needed to be.

On basis: this is where the dual test actually breaks. My all-in on the one that went sideways was 312 against an ARV I'd modeled at 415. Rent supported maybe 2,650. That's not a rental, that's a parking spot with a mortgage on it. I held it fourteen months because holding it lost less than selling it into that particular window, and then I sold it. Calling that a strategy would be generous.

So I underwrite the exit as a question, meaning I know before I buy roughly what rent the finished house commands and how far under my carry that lands. If the gap is 400 a month I can survive a stall. If it's 1,400 I need the resale to work and I should size the deal accordingly.

bramble, the input that decides this for you is your local rent-to-price relationship, and that varies enormously. Run it on three houses you've already looked at before you decide which camp you're in.

harrow, when you say you knew the rent before buying, where does that number come from on a house that doesn't exist yet? The shell rents for nothing. Do you comp it against finished rentals nearby and just assume you'll hit the top of that range?
