This is for sellers considering seller financing, subject-to, or a owner-carry note who want a real screening process instead of a gut feeling. Doing it properly takes a few hours of your time and maybe $25 to $75 in report fees. Skipping it is how sellers end up filing for foreclosure or eviction fourteen months into a deal that looked fine on paper.

What you need

• A written loan application form covering employment, income, current housing, and down payment source
• Buyer's written authorization to pull credit, plus a tri-merge credit report from a service that works with private lenders (roughly $25 to $40 per pull)
• Two to three months of the buyer's bank statements
• Proof of income: recent pay stubs, or two years of tax returns and a year-to-date profit and loss statement if self-employed
• Documentation showing where the down payment is coming from
• Contact information for the buyer's current landlord and employer, independently verified, not just whatever the buyer hands you
• A basic understanding of whether Dodd-Frank and SAFE Act rules apply to your deal, since that changes what you're allowed to ask and how you must structure payments

Step by step

1. Require a written application before anything else. A phone conversation is not a screening process. Get the buyer's full legal name, date of birth, Social Security number, current address, employer, income, and down payment source on paper. If a buyer resists filling this out, that tells you something on its own.
2. Pull credit and actually read the report. The score matters less than the pattern. A 640 with one old medical collection is different from a 640 with three late mortgage payments in the last year. Look specifically for prior foreclosures, bankruptcies, and how the buyer has handled housing debt versus credit cards. A recent bankruptcy or foreclosure doesn't automatically disqualify someone, but it changes how much down payment and reserve cushion you should require.
3. Verify income and look at real cash flow, not just a stated number. Bank statements tell you more than a pay stub. Calculate a rough debt-to-income ratio: total monthly debt payments, including the new payment you're about to add, divided by gross monthly income. Most private sellers are comfortable somewhere in the 40% to 45% range, though this is a guideline, not a rule, and it should flex based on down payment size and reserves. Also check for large unexplained deposits right before the down payment. Borrowed down payment money with no cushion left over is a common setup for early default.
4. Call the current landlord yourself, not the one on the buyer's list. Ask for the property address and look it up independently, or find the landlord through public records if you're financing a subject-to deal and want a second data point. Ask directly: was rent paid on time, was there ever a late notice, did they give proper move-out notice, what condition was the unit left in. A buyer who's never rented and is coming out of a family member's home is harder to check. In that case, weight the credit report and reserves more heavily.
5. Size the down payment to the risk you're seeing. There's no fixed number that works for every deal, but as a general pattern, the less skin a buyer has in the game, the easier it is for them to walk away when things get hard. A buyer putting down 3% to 5% with thin credit is a different risk than one putting down 15% to 20% with steady income. If you're seeing yellow flags elsewhere, a larger down payment is one of the few levers you have to offset that.
6. Meet the buyer in person, or at minimum on a video call, before you sign anything. This isn't about vibes. It's a chance to ask follow-up questions on anything unclear in the application and see how the buyer answers when they're not typing. People who are straightforward on paper are sometimes evasive in conversation, and that gap is worth noticing.

Where this goes wrong

The most common mistake is skipping the credit pull because the buyer seems nice, offers a larger down payment, or is a referral from someone you trust. Trust is not a substitute for documentation. The second most common mistake is not verifying where the down payment actually came from. A buyer who borrowed their down payment from a relative or a credit card has no reserves left when the water heater goes out in month four, and that's usually when the first missed payment happens.

Sellers also tend to accept self-employment income at face value. "I make about $6,000 a month" without a tax return or P&L behind it is a guess, not a number you should underwrite against. And a lot of sellers call the reference number the buyer gives them without checking whether that number actually belongs to a landlord at all. It sometimes belongs to a friend who's agreed to say the right things.

The consequence of skipping these steps shows up later, not immediately. A buyer with no reserves and a thin down payment can make the first three or four payments fine, then miss one after an unexpected expense. At that point the seller is looking at foreclosure or eviction costs, months of missed payments, legal fees, and getting the property back in worse shape than it left. Screening properly at the start is far cheaper than unwinding a defaulted deal later.

When to stop and call someone

If you're financing an owner-occupant buyer, find out whether Dodd-Frank's ability-to-repay requirements and the SAFE Act apply to your situation before you structure the loan. The rules depend on things like how many properties you've seller-financed in the past twelve months and whether you're acting as a dwelling-secured lender under federal definitions. This is not a place to guess. A real estate attorney or a licensed loan originator who works with private lenders can tell you in one conversation whether your deal needs a licensed originator involved, and getting this wrong can expose you to real liability.

If the buyer is purchasing through an LLC or other entity, have an attorney verify the entity is properly formed and confirm who actually has authority to sign. Don't rely on the buyer's word about their own company's structure.

And if you're seeing conflicting signals, decent credit but no verifiable income, a large down payment but a recent foreclosure, get a second opinion from someone who underwrites these deals regularly before you commit. A mortgage broker or an experienced private lender can often spot a pattern in twenty minutes that would take you weeks to notice on your own. Paper & Property covers a lot of deals where this exact screening step made the difference between a note that performed and one that didn't, and it's rarely the buyer's credit score alone that decides it. It's whether the seller actually checked.
