I own single family in Memphis, majority Section 8, and I spend most of my week answering out of state buyers trying to work out whether a deal here pencils. The thing that stops them is almost never the house. It is the debt. And inside the debt there is one specific question that nobody asks until after they have already paid for an appraisal.

Here it is.

When your lender sizes the loan, do they underwrite the contract rent on the HAP contract, or are they capped at the market rent the appraiser puts on the 1007?

Why that gap exists

On a voucher unit your contract rent is what the housing authority approved for that specific house. The 1007 is the appraiser's opinion of market rent, and it is comped against unassisted units in the area.

In a lot of voucher-heavy ZIP codes those two numbers are not the same. The adopted payment standard can sit above what an appraiser will call market rent on that street. So the owner is genuinely collecting the higher number every month, and the appraiser is genuinely reporting the lower one, and neither of them is wrong.

The question is which number your lender's guideline tells them to use.

Why it costs real money

If you are on DSCR, the ratio is computed off whatever rent figure the lender accepts. Underwrite your deal at the contract rent, have the lender size it off a lower 1007, and the ratio you were counting on is not the ratio in the file. Depending on how far apart they are, you are looking at a smaller loan, more cash to close, a pricing hit, or a decline.

And the sequencing is brutal. The appraisal is ordered before anybody tells you. So you find out you have a problem at the exact moment the money is already spent.

I want to be clear about what is NOT happening here. Your actual cash flow does not change. The voucher rent is real and it keeps arriving. What changes is how much of it the lender will let you borrow against. It is a loan sizing problem, not a return problem, which is exactly why it blindsides people who underwrote the property correctly.

What to ask, before the appraisal

Ask it in writing, and ask it as a guideline question rather than as a question about your deal, because it IS a guideline question. It does not move with your credit score or the address.

For a tenant with a housing choice voucher, do you underwrite the full contract rent with the HAP contract and lease in the file, or do you use the lesser of contract rent and the appraiser's 1007 market rent?

A good answer is specific and comes back fast, because it is written down somewhere. Something like: we use contract rent with the HAP contract and the executed lease in file. Or: we use the lesser of the two. Or: we use contract rent but cap it at a set percentage above the 1007. All three of those are fine answers. They are all usable. You can plan around any of them.

A bad answer is a version of send me a full scenario and I will check. That is not an answer about guidelines, that is an answer about workflow, and if you cannot get past it you are being asked to pay for an appraisal to discover a policy that already exists in a document.

While you are there, two more worth getting in the same email, because they are also guideline questions and also kill Memphis-style deals.

Minimum loan amount, and whether it moves on a package of several rather than one.

Minimum as-is property value. That is a different number from the loan floor and it is where more of these die than people realize. Plenty of shops quote a loan minimum in the seventies and then decline a ninety thousand dollar house.

Two asks

If you are a lender and you work this part of the market, answer the first question in the thread. Including a no. A clear no is useful and I will remember who gave me one.

If you are an owner who has financed a voucher unit, say what your lender actually did with the rent figure, and whether you found out before or after the appraisal.

I am an owner operator, not a lender. This is general education and guidelines vary by shop and by program, so confirm it against your own lender in writing rather than taking my word for it. But ask the question early, because the version of this conversation that happens after the appraisal is the expensive one.
