How Lenders Underwrite a Cash-Out Refinance to Fund a Down Payment on a New Home

How Lenders Underwrite a Cash-Out Refinance to Fund a Down Payment on a New Home

The Quick Read: The strategy runs through two separate loan files, not one. The first lender approves a cash-out refinance on the home you own, based on equity, credit, income and debt. The second lender, on the new home, treats that cash as borrowed money secured by an asset. It also counts the larger payment on the old home as a debt. Both files have to work on their own, subject to lender guidelines and full file review.

What Are You Actually Asking Two Lenders to Approve?

You are asking for two approvals, in order. First comes a new mortgage on the home you live in now. It pays off your current loan and hands you the leftover equity as cash. Second comes a purchase loan on the next home, where that cash becomes your down payment.

Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.


Nobody has a program called “cash-out refinance for a down payment.” It is two ordinary loans that interact. That is why people get surprised. The cash-out lender does not care what you do with the money. The purchase lender cares a great deal where the money came from and what it did to your monthly obligations.

Lendmire is a mortgage broker, so it does not lend. It arranges these loans through wholesale lenders. Lendmire’s cash-out refinance programs page lays out the program side. This article covers the underwriting logic behind both files.

Key Terms Defined

Cash-out refinance: A new first mortgage larger than the one it replaces. The difference, after costs, comes to you as cash.

Loan-to-value (LTV): The loan amount divided by the home’s appraised value. An 80% LTV means the loan equals 80% of value. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Debt-to-income ratio (DTI): Your total monthly debt payments divided by your gross monthly income. Lenders call this the total ratio.

Seasoning: The time that must pass before you can do a transaction. It applies to how long you have owned the home and how old your current loan is.

Reserves: Money left in your accounts after closing. Lenders count it in months of housing payments.

Sourcing of funds: The paper trail showing where your down payment came from.

How Is the Cash-Out Refinance Underwritten, Step by Step?

Here is the sequence a cash-out file follows. Each step can stop the file.

1. Classify the loan. The lender first decides whether this is a cash-out or a rate-and-term refinance. Taking more than a small amount of cash back makes it a cash-out. Everything below follows from that label.

2. Check seasoning. The mortgage being paid off generally has to be at least 12 months old, measured note date to note date. At least one borrower must also have been on title for six months. Exceptions exist for delayed financing, inheritance and legal awards. Fannie Mae’s cash-out guide states the six-month title rule.

3. Appraise the home and size the loan. The appraisal sets the value. Then leverage limits apply. For a conventional cash-out, the limit is 80% LTV, and the ceiling can be lower depending on occupancy and property type. Occupancy sets the leverage, so the same home can carry different limits depending on how you use it.

4. Test income, debt and credit. The wholesale conventional programs start at a 620 decision score. The automated underwriting finding governs most files, with a total ratio ceiling of 50%. Manually underwritten loans run tighter, at 36% or 45%, with reserve and score factors from the program’s matrix.

5. Check reserves. On an automated Fannie Mae file, a DTI above 45% triggers a six-month reserve requirement. Hold that thought. It matters when you are trying to put every dollar into a down payment.

6. Review the costs and disburse. The Loan Estimate shows what the loan costs. Costs can be paid out of pocket, taken from proceeds or financed into the loan. Any amount rolled in lowers your cash.

The question to ask a lender at the start is simple: how much cash will I net after costs? The gross number is not the number that reaches your account.

How Does the Purchase Lender Treat the Cash?

The purchase lender looks at the same dollars from a different angle. It asks three things. Is the money allowed? Is it documented? What did it do to your debt load?

Is it allowed? Fannie Mae accepts borrowed funds secured by an asset as a source for the down payment, closing costs and reserves. It treats them as a return of equity. Its selling FAQ covers this topic. An unsecured personal loan is a different story, and lenders view it very differently.

Is it documented? Unverified funds do not count toward the down payment. The purchase lender traces the money. On a purchase, large deposits needed to complete the deal must come from an acceptable source, and undocumented amounts are subtracted from your verified funds, per Fannie Mae’s depository account rules. Your cash-out proceeds will land in your bank account as a big deposit. The refinance Closing Disclosure is the document that explains it.

What did it do to your debt? Loans secured by real estate are entered as a mortgage liability. So the new, bigger payment on the old home goes into your DTI on the purchase application. There is no such thing as invisible debt here.

Agency guidelines also place no restriction on how cash-out proceeds are used. Seasoning wording differs between the agencies, so a single “agency rule” statement is unsafe. A broker checks which rule set the target lender follows.

Factor Cash-out refinance file Purchase file
Property The home you own now The home you are buying
Core test Equity and LTV limit Down payment and sourcing
Role of the cash The product Borrowed funds, traced
Debt counted New payment on old home Both mortgages, if old home kept
Timing hurdle Seasoning on title and loan Documented funds before approval

What Does This Look Like in Percentages?

Run the numbers on a modeled homeowner. These inputs are assumptions, not market data.

Say the old home is a one-unit primary residence. The current loan balance is 50% of its appraised value. A conventional cash-out on a primary residence can often reach higher leverage than a DSCR cash-out, which is capped at 75% LTV. For this example, assume the new loan is 80% of value. It pays off the 50% balance and leaves up to 30% of value as cash, before closing costs. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Now subtract the costs. Suppose they are financed, or paid from proceeds. Cash drops below 25% of the old home’s value.

Next, the purchase. Assume the new home costs about the same as the old one. A new primary residence typically allows up to 90% LTV on an agency loan, so the down payment is 10%. You do not need most of that cash. Use 10% for the down payment, and some for closing costs. Plenty is left for reserves.

Here is the catch. The old home’s loan balance went from 50% of value to 80%. That is a balance 60% larger. The payment rises accordingly. If you keep the old home, that bigger payment sits in your DTI beside the new mortgage. A borrower who looked comfortable at one mortgage can drift toward the 45% mark, where reserves kick in. Past the 50% ceiling on the automated programs, the file stops working.

The strongest play here is often a smaller cash-out. Take what the purchase file needs, plus a cushion. Not the maximum the appraisal allows.

How Much Cash Should You Take Out?

Take the least cash that comfortably solves the purchase. A bigger cash-out feels like safety. It also raises the payment on a home that you may still own, and it uses up equity you might want later.

Three levers decide the number:

  • Down payment needed. A new primary residence usually needs less cash than a second home, so occupancy of the new home changes the math. Cash-out leverage on the old home is a separate limit: 80% on a one-unit primary residence, and 75% on two- to four-unit homes, second homes and rentals.
  • Cost of the loan. A cash-out refinance is a new first mortgage with its own closing costs. There is no standard percentage. Your Loan Estimate shows the real figure.
  • Reserves. If your DTI will exceed 45% on an automated file, plan for six months of reserves. Cash that serves as both down payment and reserves can only be spent once.

This one is a genuine judgment call. A larger down payment may reduce mortgage insurance on the new loan, since insurance is generally required above 80% LTV. The wholesale no-mortgage-insurance cash-out lane is the exception to that rule, and it applies only to the refinance, not to the purchase. But a larger cash-out also means a larger payment on the old home. Brokers who shop several wholesale lenders can price both versions of the plan, so the borrower sees the trade-off side by side.

Where Does the General Rule Break?

Limited cash-out is not a workaround. A rate-and-term (limited cash-out) refinance allows only incidental cash back. Fannie Mae’s figure is the lesser of 2% of the new loan amount or $2,000. That will not fund a meaningful down payment. Take more, and the file is underwritten as a full cash-out, with the lower leverage limits.

The FHA Streamline and VA IRRRL cannot fund a down payment. HUD’s streamline page caps cash at $500 on an FHA Streamline. A VA IRRRL is built for lowering the cost of an existing VA loan, per VA’s refinancing chapter, and it is not a cash vehicle. A homeowner with an FHA or VA loan who wants cash needs a separate, fully underwritten cash-out product, and the rules for that product are different.

Delayed financing. If you bought your current home with cash, you do not have to wait out the six months on title. You can still pull cash out under the delayed financing exception. It is underwritten as a cash-out. The purchase closing documents must show no financing was used, and any borrowed purchase funds have to be repaid at the refinance closing.

A home that is listed. If your current home is on the market, Fannie Mae requires it to be taken off the market by the time the cash-out loan funds. Selling instead is a different file, using sale proceeds.

Texas homesteads. A cash-out on a Texas homestead is capped at 80% of the home’s value by the state constitution, whatever the agency limit says. The wholesale no-mortgage-insurance lane is not written there.

The no-mortgage-insurance lane. One wholesale lane reaches 89.99% LTV with no mortgage insurance. It needs a 680 score, a 50% ratio ceiling and a thirty-year fixed loan on a primary residence at a conforming balance. It has its own six months of seasoning. It is narrow, but it can matter for a homeowner with strong credit and a lot of equity. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Keeping the old home as a rental. Occupancy sets the leverage, and rental use falls under the 75% limit. Say so up front if that is your plan.

Credit events. Waiting periods after a bankruptcy or foreclosure are set by the agencies. The common ones are four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu. Documented extenuating circumstances can shorten them.

What About a HELOC or a Contingent Sale?

A cash-out refinance replaces your whole first mortgage. A home equity line or second mortgage leaves it alone and adds a second lien. If your current loan is one you want to keep, a second lien can look attractive. The purchase lender still counts it as debt and still traces the funds. A third path is to sell the old home first, then buy with sale proceeds. That removes the second payment, but it means finding temporary housing or writing a contingency into your offer.

Which fits best depends on your current loan, your equity and how long you plan to hold both homes. Not every lender writes every structure, which is the practical case for using a broker.

What Should You Have Ready?

Planning has to begin well before the purchase contract. The two clocks, six months on title and 12 months on the old loan, can break a buying timeline. Gather the items below early, since they are the documents and decisions that keep both clocks from catching you off guard:

  • Recent pay records, tax documents and bank statements.
  • The current mortgage statement and homeowners insurance declaration.
  • A written plan for the old home: keep, rent or sell.
  • The refinance Closing Disclosure, once you have it, kept with the bank statement that shows the deposit.
  • Letters explaining any other large deposits.

Keep the proceeds in a single account with a clean history. Moving money around makes the paper trail harder to follow.

What Does Your Decision Look Like in Practice?

Work backward from the purchase. Decide the down payment, the closing costs and the reserves you want. That is your cash need. Then see whether a cash-out refinance, a limited cash-out, a second lien or a sale gets you there with a payment you can carry.

Frequently Asked Questions

Can I use cash-out refinance money as a down payment on another home?

Generally yes. A cash-out refinance carries no restriction on how you use the proceeds. The purchase lender accepts borrowed funds secured by an asset as a down payment source. It will trace the money and count the new payment as debt. Qualification on both files is subject to lender guidelines.

Does having the cash mean I will be approved for the new loan?

No. Cash solves the down payment, not the income test. The purchase lender still checks credit, reserves and your total ratio with both mortgages included. Many files that look fine on paper at one mortgage stall at two.

How long do I have to own my home before I can cash out?

Generally at least one borrower must have been on title for six months. The loan being paid off typically has to be at least 12 months old, note date to note date. Different agencies word these rules differently.

Can an FHA Streamline or VA IRRRL give me cash for a down payment?

No. HUD caps cash on an FHA Streamline at $500, and the VA IRRRL is designed to reduce the cost of an existing VA loan. A borrower wanting real cash needs a separate FHA or VA cash-out loan, which is fully underwritten.

Will the new payment on my old home count against me?

Yes. If you keep the old home, both payments go into your DTI. A ratio above 45% on an automated file can trigger six months of reserves, and the programs stop at a 50% ceiling.
