What are the appraisal requirements for non-QM, DSCR and bank statement loans?

Non-QM means the lender writes the rulebook

A non-QM loan is a mortgage that falls outside the standard "qualified mortgage" box. DSCR loans qualify an investor on the property's rent. Bank statement loans qualify self-employed borrowers on deposits instead of tax returns.

The important part for appraisals: these loans are not bought by Fannie Mae or Freddie Mac, so those agencies' appraisal rules don't automatically apply. Each lender and the investor buying the loan set their own requirements. Some borrow chunks of Fannie Mae's rules. Some go stricter. You only know by reading the program.

That means two DSCR lenders across the street from each other can have different age limits, different review rules and different rent rules. It's like two restaurants that both serve "tacos" and one of them means a hot dog in a tortilla.

On a bank statement loan, the special part is how income is documented, not the property, so the appraisal itself tends to look like a normal purchase or refinance appraisal. DSCR loans add a rent piece, which is where most of the surprises live.

One real DSCR program, as an example

To make this concrete, here's what one wholesale lender's published DSCR program (Homebridge DSCR Plus, guidelines dated July 20, 2026) says about appraisals. This is one program, not an industry rule.

• New full appraisal: all transactions require one. One full appraisal for loans up to $1,500,000.
• Age limit: the appraisal may not be more than 120 days old on the note date.
• Recertification of value: allowed to extend the report only if the original is not more than 180 days old on the note date.
• Second appraisal: brokers may order one at their own cost. If approved, the lower of the two values is used.
• Transferred appraisals: require a desk review by the lender's appraisal department.
• Condition: properties rated C5 or C6 are ineligible unless repairs are finished and an updated appraisal rates the house C4 or better. Rural properties, short-term rentals and some other types are out.

Compare that with Fannie Mae, where a conventional appraisal can be used up to 12 months with an update. Investors who move from a conventional loan to a DSCR loan often get caught by the shorter clock.

How rent gets counted on a DSCR loan

DSCR stands for debt service coverage ratio. In plain words, it compares the property's rent to its monthly housing payment. That same Homebridge program sets a minimum of 1.00, meaning the rent has to at least cover the payment.

The appraiser's market rent opinion becomes a big deal here. In that program:

• Purchase: the base rule is the lesser of the current lease rent (leases required if the unit is rented) or the appraiser's market rent. The program has exceptions, such as allowing up to 120% of market rent when the lease runs at least six months past the note date and three months of rent history is documented.
• Refinance: the same lesser-of approach, and the current lease has to be provided.
• Vacant refinance: properties that are currently vacant are ineligible.

"Lesser of" cuts both ways. If you signed a tenant at a great rent, the market rent opinion may cap it. If your rent is below market because your tenant is your cousin, the lease caps it. Under the base rule, the lower number wins.

Market rent is measured like value: from comparable rentals, adjusted for differences. Your property manager's optimism is not a comparable rental.

When I write a market rent opinion, I look for rentals that match the unit: bedrooms, baths, size, parking, laundry, condition and location. Then I adjust for what renters actually pay extra for. A unit with in-unit laundry and a parking space is not the same product as one with a coin-op machine down the hall, and the rent comparison should show that.

Desk reviews, AVMs and the 10% line

Many non-QM programs double-check the appraisal. In the Homebridge DSCR Plus guidelines:

• A CDA (a collateral desk analysis, which is a desk review of the appraisal by another party) is required on a one-unit property when both agency risk scores (CU and LCA) are above 2.5, and on every 2 to 4 unit property or any file missing a score.
• If the CDA value is within 10% of the appraisal, the appraisal is acceptable, subject to underwriter review.
• If the CDA variance is more than 10%, the file goes to the lender's appraisal department, which orders an AVM.
• That AVM (automated valuation model) is the tiebreaker. If it is within 10%, the appraised value sets the loan-to-value. If not, the program falls back to other values depending on the transaction.

For investors, this means a stretched appraisal doesn't just sit there. Somebody checks it, and if it is more than 10% off, the file slows down while people with very serious faces read it again.

What investors and loan officers should do

1. Get the actual guidelines for the program, with the date on them. Non-QM rules change often.
2. Check the age limit against your closing date. 120 days is very different from 12 months.
3. Ask if a transferred appraisal is accepted and what review it triggers.
4. Know your rent numbers. Pull comparable rentals before you apply, and bring copies of current leases.
5. Don't refinance a vacant unit on a program that bans it. Lease it up first if the math requires it.
6. Expect a desk review on higher-risk files and 2 to 4 unit properties.
7. Get a realistic value early. An evidence-based read before you apply tells you whether the deal works at the lender's loan-to-value.

Facts over feelings applies double to investors. The spreadsheet always looks better at midnight than it does at the appraisal.
