The Quick Read: There is no single income figure that unlocks a loan this size. Your income is the output of a ratio test, not a fixed number. The test divides your new total monthly obligations by your gross monthly income and compares the result to a ceiling. Equity sets how large the loan can be, and income sets whether the payment fits.
Key Takeaways
- “$400K” can mean $400K of cash in your hand or a $400K new loan. They are different problems, and the math below treats them separately.
- On a conventional loan, the new balance usually tops out at 80% of the home’s appraised value on a one-unit primary home.
- Required income equals your new housing payment plus your other monthly debts, divided by the DTI ceiling.
- A larger payment raises the income you need. A smaller cash-out lowers it.
- Limited cash-out refinances, FHA Streamlines and VA IRRRLs are not tools for pulling $400K.
What Does “$400K” Actually Mean?
It can mean three things: $400K of cash to you, a $400K new loan, or $400K of equity. Each one needs a different home value, so pin down which you mean before you run any numbers.
Here is the cash-to-you version. Cash out is roughly 80% of the appraised value, minus the payoff of your existing liens, minus closing costs and prepaid items. Those prepaids are items like taxes and insurance funded at closing.
Take a home with no mortgage. To net $400K, the appraised value must be at least 1.25 times that amount, and more once costs come out. A home with a mortgage balance needs a higher value still, because the payoff comes off the top first.
Now the new-loan version. If $400K is the new loan, the appraised value must be at least 1.25 times the loan on a one-unit primary home. The cash you receive is whatever is left after payoff and costs.
Paid-off homes still count as cash-out. The lender treats any refinance that returns equity as cash-out, whether or not a mortgage exists today.
What Is a Cash-Out Refinance, and What Isn’t?
A cash-out refinance replaces your current mortgage with a larger one and pays you the difference. A refinance only replaces the old loan, plus costs. A conventional rate-and-term (limited cash-out) refinance reaches 95% LTV on a one-unit primary home. That is exactly why it can’t deliver large cash: it allows only incidental cash back. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
LTV means loan-to-value. It is the loan balance divided by the appraised value.
Two other products get confused with cash-out:
- FHA Streamline: for an existing FHA loan, with no appraisal and a limited credit review. It requires a net tangible benefit and pays the borrower no meaningful cash.
- VA IRRRL: for an existing VA loan. It exists to reduce the cost of the loan you already have, not to tap equity.
Both are useful tools. Neither funds a $400K cash-out. If you hold an FHA or VA loan and want large cash, the real options are the FHA or VA cash-out programs, or a conventional cash-out.
Many homeowners mix these up because the word “refinance” covers all of them. Lendmire’s cash-out refinance programs are built around the equity side of the question. The streamlines are built around the payment side.
How Is a Cash-Out Refinance Underwritten, Step by Step?
Underwriting follows a repeatable sequence. Across the wholesale programs Lendmire places files with, the order below holds on nearly every file.
1. Define the amount. You and the loan officer settle whether you want a target cash figure or a target loan size.
2. Application and income documentation. The lender builds your qualifying income from verified, stable income. Typical documents include pay stubs, W-2s, traditional personal-income documentation for self-employed borrowers, and bank statements.
3. Credit and liabilities. The lender pulls credit and lists every recurring debt. The new housing payment goes into the ratio along with the other debts.
4. Appraisal and LTV. The appraised value sets the ceiling. Every lien that stays on the home counts toward the combined LTV.
5. Pricing and program fit. Credit score and LTV both affect how the loan is priced, and a cash-out refinance is priced on its own grid. Higher LTV and a lower score push cost up. Your Loan Estimate shows the actual terms.
6. Re-check before closing. New debt, or a new second lien, can force the lender to run the file again.
7. Closing and disbursement. Net cash equals the new loan minus the payoff, fees and prepaids. The final figure depends on the payoff, the fees and underwriting approval.
Every program is subject to lender guidelines and full file review. Nothing here is a commitment to lend.
How Much Income Do You Need for a $400K Loan?
You need enough gross monthly income that your total monthly obligations stay under the DTI ceiling. Here is the formula:
Required gross monthly income = (new housing payment + other monthly debts) ÷ DTI ceiling.
DTI means debt-to-income ratio. The Consumer Financial Protection Bureau defines it as all monthly debt payments divided by gross monthly income, which is income before taxes and deductions. It also notes that different loan products and lenders set different limits.
The “new housing payment” is the whole thing: principal, interest, property taxes, homeowners insurance, HOA dues and mortgage insurance if it applies. Many borrowers count only principal and interest, then wonder why the lender’s number is higher.
Now the ceiling. For loans run through automated underwriting, the Fannie Mae Selling Guide sets the maximum DTI at 50%. For manually underwritten loans, the base is 36%, and up to 45% is allowed when credit score and reserves meet the Eligibility Matrix. The guide also says the maximum may be lower on cash-out transactions run through automated underwriting. Do not assume a cash-out gets the full 50%.
You can turn that into a multiple. Here is what each ceiling demands of your income:
| DTI ceiling | Income must be at least | Where it shows up |
|---|---|---|
| 36% | about 2.8x monthly obligations | Manual underwriting, base |
| 45% | about 2.2x monthly obligations | Manual, strong score and reserves |
| 50% | 2.0x monthly obligations | Automated findings; cash-out may be lower |
To use the table, add your expected new housing payment and your other monthly debts. Multiply by the figure in the row that fits. That is the gross monthly income you need. Multiply by 12 for the annual version.
A short example, in ratios only. Say your new housing payment and your other debts together equal one unit of obligation. At a 45% ceiling, your gross monthly income must be about 2.2 units. At 50%, it must be 2.0. Pay off a car loan at closing, and the unit shrinks.
Debts matter as much as the new loan. A borrower with a $400K loan and no other debt can qualify on less income than a borrower with the same loan and heavy car and card payments. Installment debts with only a few payments left can often be excluded under agency rules, and revolving balances paid off at closing may not count. Ask your loan officer which of your debts qualify for that treatment.
Which Income Counts, and How Is It Documented?
Income that is stable, documented and likely to continue counts. The document set varies by income type, and the lender decides what it needs in your file.
| Income type | General treatment | Typical documents |
|---|---|---|
| Wages | Verified, stable history | Pay stubs, W-2s |
| Self-employed | Based on documented net income | Traditional personal-income documentation, bank statements |
| Commission or bonus | Needs a documented history | Pay stubs, traditional personal-income documentation |
| Retirement or pension | Counts if it continues | Award letters, statements |
| Unit or rental income | Treated by program rules | Leases, traditional income documentation |
Self-employed borrowers hit a common snag. Conventional personal-income paperwork often shows less income than the business actually produces, because deductions shrink the bottom line. Lendmire has a piece FHA Cash-Out Refinance for Homeowners Whose Tax Returns Understate Income if that sounds like you.
Retirees face the mirror-image problem. Their income may come from assets, not a paycheck. Lendmire’s explanation of how a retiree can qualify for a cash-out refinance on asset income covers that path.
The point for either borrower: the lender judges what it can verify, not what you believe you earn. Gather documents before you apply.
How Much Equity Do You Need?
On a conventional cash-out refinance, the cap is 80% LTV on a one-unit principal residence and 75% on two- to four-unit principal residences. The Fannie Mae Eligibility Matrix lays out those caps, and they are the reason “I have $X of equity” doesn’t mean you can take $X out. The cap leaves a cushion. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Work it backward from a $400K new loan:
- At 80% LTV on one unit, the home must appraise at 1.25 times the loan.
- At 75% LTV on two to four units, the home must appraise at about 1.33 times the loan. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
One wholesale lane stretches further. It reaches 89.99% LTV with no mortgage insurance, at a 680 score and a 50% ratio, on a thirty-year fixed, primary residence with a conforming balance. It carries its own six months of seasoning. It is not written in Texas, where a homestead cash-out is capped by the state constitution at the agency figure. Other states also have their own cash-out rules. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
For FHA, HUD Mortgagee Letter 2019-11 cut the maximum LTV and CLTV on cash-out refinances to 80%. The cap covers combined debt, so a second lien or HELOC that stays in place counts. Closing or paying down the HELOC may free room.
Seasoning rules apply as well. On a conventional cash-out, the first mortgage being paid off must be at least 12 months old, counted note date to note date. You also need to have been on title for 6 months. Exceptions exist for delayed financing, inheritance and legal awards.
What Do Credit Scores Do to a $400K Cash-Out?
Credit affects whether you qualify and what the loan costs. Wholesale conventional programs start at a 620 decision score. The automated finding governs most files. Manual underwriting uses the score and reserve factors in the Eligibility Matrix.
Your score also moves pricing. Lower scores and higher LTVs both raise the cost. A borrower at 80% LTV with a modest score may find the same loan priced noticeably higher than a borrower with a strong score at 65% LTV. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Past credit events carry waiting periods set by the agencies: 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.
Conventional, FHA and VA: Which Fits?
Each program gets you to a different place. Here is the side-by-side for a borrower seeking large cash:
| Factor | Conventional | FHA | VA |
|---|---|---|---|
| Cash-out LTV cap | 80% one unit | 80% LTV/CLTV | Set by VA and lender |
| Occupancy | Primary residence for best leverage | Owner-occupied | Home you will live in |
| Existing-loan test | 12-month first mortgage | Occupancy history applies | Certificate of Eligibility |
| Jumbo option | Yes, above conforming | Limited | Lender dependent |
On VA, the VA’s cash-out page lists three conditions, all of which must be true. You qualify for a Certificate of Eligibility. You meet VA’s and your lender’s credit and income standards. You will live in the home you are refinancing. Lenders can set leverage below the program maximum.
A $400K loan may exceed the conforming limit in some counties. When it does, the jumbo lanes take over. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. The ratio ceiling is 50% on the fixed lanes. County loan limits change, so the lender confirms where your balance falls.
Where Does the Standard Math Break?
Four edge cases trip people up.
A non-occupant co-borrower. Adding a co-borrower who doesn’t live in the home can help income. But when a non-occupant’s income is used, the occupying borrower’s DTI limit is lower. It helps on income and costs you ratio room.
A second lien that stays. A HELOC or second mortgage still on the home counts toward combined LTV. That shrinks your cash. Paying it off from proceeds is common.
Payment shock. If your current mortgage balance is small and its payment low, a $400K new loan replaces that with a much larger payment. The cash-out can look affordable on a ratio and still stretch the budget. Compare the old and new payments before you commit.
Two to four units. The lower 75% cap applies. A home on a second-home or investment basis falls under different rows of the matrix. For a borrower living in the home, occupancy is what decides the leverage.
Which Misconceptions Are Costing You Money?
Several beliefs lead borrowers astray.
- “Lenders cap DTI at 43%.” The 43% figure was the original qualified-mortgage test. The CFPB’s own guidance says limits vary by product and lender, and automated findings can go higher.
- “My equity equals my cash.” The 80% cap, plus payoff and costs, takes a bite.
- “A limited cash-out lets me pull cash.” It allows only a small amount back.
- “Big equity means I skip the income check.” Lenders must make a documented, good-faith decision that you can repay the loan. Equity does not waive that.
- “My DTI hurts my credit score.” Credit scoring does not use income. DTI is a measure lenders use to judge your payment load.
- “I don’t earn enough, so I shouldn’t apply.” Fannie Mae research has found that many consumers underestimate the maximum DTI the program allows, and may disqualify themselves.
What If Your Income Falls Short?
Fix the ratio from whichever side moves. The four levers, in the order most borrowers try them:
1. Lower the cash-out amount. A smaller loan means a smaller payment, so a lower income threshold.
2. Pay off debts first. Retiring a car loan or card balance cuts the monthly obligations in your formula.
3. Add a co-borrower. Their income raises the income side of your qualifying math (the denominator of the debt-to-income ratio), subject to the occupancy caveat above.
4. Change the structure. A different program, or leaving the first mortgage in place and adding a separate second lien, may fit your numbers better. Compare the full terms on the Loan Estimate.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Key Terms Defined
DTI (debt-to-income ratio): your total monthly debt payments divided by your gross monthly income.
LTV (loan-to-value): the loan balance divided by the home’s appraised value.
CLTV (combined loan-to-value): the total of all liens on the home divided by its appraised value.
Seasoning: the waiting period a lender wants before you can refinance, such as time on the existing mortgage or on title.
Net tangible benefit: a required, measurable gain from a streamline refinance, such as a lower payment.
Delayed financing: an exception that lets a recent cash buyer refinance and take cash out before the usual seasoning period ends.
Before You Apply: A Short Checklist
- Decide whether $400K is your cash target or your loan size.
- List every monthly debt and its remaining payments.
- Estimate the home’s value conservatively, because the appraisal decides the cap.
- Gather income documents for each source you plan to use.
- Compute your own DTI with the new, larger payment.
- Ask whether you hold a second lien that will remain.

Frequently Asked Questions
How much do I need to earn for a $400K cash-out refinance?
It depends on your new total monthly payment and your other debts. Divide that sum by the DTI ceiling your program allows. At a 45% ceiling you need about 2.2 times your monthly obligations in gross income, and at 50% about 2.0 times. Cash-out loans may get a lower ceiling than other loans, subject to lender guidelines.
Can I qualify on retirement or self-employment income?
Often yes, if the income is documented and likely to continue. Retirees may use pension and asset income. Self-employed borrowers typically document with standard personal-income documentation or bank statements, depending on the program. The lender decides what it accepts after reviewing your full file.
Does a limited cash-out refinance let me take $400K?
No. It allows only incidental cash back, enough to cover costs and a purchase-money second lien. Large cash out requires a true cash-out refinance, which carries a lower leverage cap.
Why is my cash smaller than my equity?
The 80% cap on a one-unit primary home leaves a cushion. Your payoff, closing costs and prepaid items also come out of the proceeds. A second lien that stays on the home counts against the cap too.
Does a larger cash-out change my mortgage insurance?
Mortgage insurance applies above 80% LTV on conventional loans. It cancels at your request at 80% of original value, with a good payment history, no subordinate liens and no decline in value. The servicer ends it automatically at 78%. One wholesale lane reaches 89.99% LTV without mortgage insurance, at a 680 score. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
