Seller Financing – How Much Can The Buyer Afford? - Alpine West

How to Estimate What a Buyer Can Afford

You don't need to rely on one percentage. Start with four parts of the buyer's financial picture.

• Verified income: Review the income the buyer reasonably expects to use for the payments.
• Existing debt: Include recurring obligations such as car loans, credit cards, and other monthly debt payments.
• Total housing cost: Look beyond principal and interest to property taxes, insurance, and other required housing expenses.
• Cash upfront: Make sure the buyer can cover the agreed down payment and applicable closing costs without leaving the payment plan unrealistic.

What About the 28% and 36% Rules?

A common screening guideline compares housing costs with about 28% of monthly income and total monthly debt with about 36%.

Those percentages can be a quick reference, but they aren't a universal approval standard. A buyer's full financial picture and the rules that apply to the transaction matter more than one ratio.

Simple Seller Financing Affordability Example

Suppose a buyer earns $4,000 per month and already pays $500 toward other monthly debts.

• Income: $4,000 per month.
• Existing debt: $500 per month.
• Proposed housing cost: Include the mortgage payment, taxes, and insurance.
• Cash available: Confirm the buyer can handle the down payment and closing costs too.

The goal isn't to stretch the payment to the highest possible number. It's to understand whether the buyer can reasonably support the agreement over time.

Verify the Numbers Before Creating the Note

Depending on the transaction, documents used to understand ability to pay may include pay statements, W-2s, tax returns, benefit income, bank statements, or other support for expected income.

Federal rules can also apply to seller-financed residential transactions. CFPB guidance for certain seller financers discusses making a good-faith determination of the buyer's reasonable ability to repay.

See CFPB Regulation Z Section 1026.36 .

A qualified attorney, loan originator, or other professional familiar with seller financing can explain which federal and state requirements apply to a specific transaction.

Why Buyer Affordability Matters to Your Mortgage Note

Once the sale closes, the buyer's promise to pay becomes your mortgage note. The terms you create today can affect how that note performs and how a note buyer evaluates it later.

Factors that can matter include:

• Down payment: More buyer equity can provide additional protection in the transaction.
• Monthly payment: A payment the buyer can maintain may support a cleaner payment history.
• Interest rate: The rate affects both the payment and the future economics of the note.
• Payment history: Consistent records help show how the note has performed after closing.

If you later want cash instead of continuing to collect payments, you may be able to sell the full note or only part of the future payment stream.
