Non-QM Refinance Process: Steps, Documents, and Costs

A non-QM refinance replaces an existing mortgage with a new loan that does not meet the Consumer Financial Protection Bureau’s qualified mortgage (QM) standards. The process is to check eligibility with a lender, document income and assets using the lender’s accepted method, submit a complete application, undergo property and underwriting reviews, then review and sign the final loan documents if approved.

Formula

This calculator estimates the new loan’s monthly principal-and-interest payment when the current balance and chosen closing costs are refinanced into a fixed-rate loan. It does not determine whether a borrower qualifies or whether refinancing reduces total costs.

The loan amount used in the payment formula is L = B + F. The monthly payment is M = L × r ÷ [1 − (1 + r)⁻ⁿ], where r = APR ÷ 1,200 and n = 12 × years. The displayed payment is rounded to cents. Scheduled payments are T = M × n; estimated interest is I = T − B − F.

• B: current mortgage balance, in dollars.
• F: closing costs assumed to be added to the new loan, in dollars.
• L: estimated new principal, in dollars.
• APR: annual percentage rate entered as a percentage; the calculator uses APR divided by 12 for a monthly rate.
• r: monthly interest rate as a decimal.
• n: number of monthly payments.
• M: estimated monthly principal-and-interest payment, in dollars.
• T: total scheduled payments over the full term, in dollars.
• I: estimated interest within those payments, in dollars.

Worked Example

Using the defaults: balance B = $400,000, financed costs F = $8,000, APR 7%, and term 30 years.

1. New principal: L = $400,000 + $8,000 = $408,000.
2. Monthly rate: r = 7 ÷ 1,200 = 0.0058333333; payment count: n = 30 × 12 = 360.
3. Substitute: M = 408,000 × 0.0058333333 ÷ [1 − (1.0058333333)⁻³⁶⁰] = $2,715.63, rounded to cents.
4. Total scheduled payments: T = $2,715.63 × 360 = $977,626.80.
5. Estimated interest: I = $977,626.80 − $400,000 − $8,000 = $569,626.80.

Assumptions

• The interest rate is fixed throughout the entered term.
• Payments are monthly and made at the end of each period.
• Interest accrues monthly using APR divided by 12.
• Only the entered financed costs are included. The estimate excludes other fees, taxes, insurance, private mortgage insurance, escrow, and any prepaid interest unless represented in the inputs.

What Makes a Refinance Non-QM?

“Non-QM” describes a mortgage that does not satisfy one or more requirements for classification as a qualified mortgage. It does not, by itself, mean that a loan is illegal, unsuitable, or automatically risky; nor does the label guarantee a particular underwriting method. Lenders still have to assess the application under applicable requirements, and their products and documentation policies differ.

Non-QM refinancing may be considered when standard income documentation does not represent a borrower’s finances well. Examples of documentation approaches some lenders may assess include bank-statement cash-flow records for self-employed applicants, asset-based qualification, or documentation of rental income. These are examples, not promises of availability or approval. A lender decides which methods it accepts and what evidence it requires.

Process: From Initial Review to Closing

1. Define the purpose. Clarify whether the aim is to replace a current loan, change the term, access equity, or address a documentation issue. Cash-out transactions and rate-and-term refinances can involve different requirements.
2. Request a written estimate. Ask about the proposed loan amount, rate structure, term, fees, required cash at closing, and whether costs are paid upfront or financed. Rates and fees are lender-specific inputs; obtain current figures directly from the lender.
3. Gather records. Depending on the underwriting method, documents can include identification, mortgage statements, bank statements, tax or business records, asset statements, lease agreements, and proof of insurance. Ask which periods and formats are required.
4. Submit the application and authorizations. The lender reviews the application and may request additional documentation or permission to verify financial and property information.
5. Complete valuation and underwriting. The lender may arrange an appraisal or another valuation review, assess the property and title, verify documents, and evaluate the requested loan. Respond promptly to requests and check that figures and explanations are consistent.
6. Review final disclosures and close. Compare the final loan amount, payment, rate type, term, financed costs, cash due, and any prepayment provisions with the earlier estimate. Ask questions about discrepancies before signing. Funding and payoff timing depend on the transaction and lender.

Documents, Costs, and Comparing Offers

The documentation is shaped by the method used to assess repayment capacity. For a bank-statement approach, for example, the lender may ask for a defined sequence of personal or business statements and explain how deposits are treated. Gross deposits are not necessarily the same as qualifying income: transfers, loans, refunds, and business expenses can affect the lender’s calculation. For an asset-based approach, ask how assets are verified and converted into an income or repayment assessment.

Refinancing can involve origination, appraisal, title, recording, and other transaction charges, as well as prepaid items. The exact categories and amounts vary; do not assume that “no-cost” means there are no costs, since charges may be offset, included in the loan, or reflected in pricing. Compare the written estimates on the same assumptions, including loan amount, term, rate type, and whether fees are financed. Financing costs raises the principal and can increase interest over time.

Compare more than the new monthly payment. A longer term can lower the scheduled payment while extending repayment and increasing the amount of interest paid over the full schedule. A lower payment also does not establish savings if closing costs, a changed rate, or a new starting term offset it. Request a payoff amount for the existing mortgage and a written estimate of the new loan’s total charges and payment schedule. The calculator above is illustrative arithmetic, not a break-even or qualification calculator.

Common Problems and Misconceptions

• Assuming non-QM means no income checks: Alternative documentation is not the same as no underwriting. Expect verification suited to the lender’s method.
• Using the wrong balance: A mortgage statement balance may differ from the payoff amount because of accrued interest or other adjustments. Ask for a current payoff figure.
• Overlooking cash to close: Costs may be paid upfront rather than financed. Confirm which charges are included in the proposed loan amount.
• Focusing only on payment: Payment comparisons can mislead when terms, fees, or rate structures differ.
• Assuming preapproval is final approval: A preliminary review can be conditional. Underwriting, valuation, title review, and final documentation can still affect the outcome.

Frequently Asked Questions

How long does a non-QM refinance take?
The timeline varies by lender, documentation method, property review, and how quickly requested information is supplied. Ask the lender for an estimated schedule and what could delay it.

Can I refinance with bank statements instead of tax returns?
Some lenders offer bank-statement underwriting, but availability and requirements differ. Ask whether personal or business statements are accepted, what period is needed, and how deposits and expenses are evaluated.

Does a non-QM refinance require an appraisal?
A lender may require an appraisal or another valuation process. The requirement depends on the transaction and lender; confirm it before relying on a proposed timeline or cost estimate.

Can closing costs be added to the new loan?
They may be financed in some transactions if the lender and loan structure allow it. Financing costs increases the balance, so request a written breakdown of financed charges and cash due.

Is non-QM the same as a subprime mortgage?
No. Non-QM refers to a mortgage’s status relative to qualified-mortgage standards, while “subprime” is a separate term often used to describe borrower or loan risk. The labels are not interchangeable, and the loan’s actual terms and underwriting matter.
