The Quick Read: Owing 70% of your home’s value puts you under the leverage cap, and the cap sets your cash. On a one-unit primary residence, conventional cash-out tops out at 80% of value, which leaves about 10% of value as headroom before closing costs. Credit, income, debt ratio, reserves and the appraisal then decide whether the loan is approved. All of this is subject to lender guidelines and full file review.
What Does Owing 70% Actually Mean to an Underwriter?
It means your loan-to-value ratio (LTV) is 70% today. LTV is your mortgage balance divided by the home’s appraised value. A cash-out refinance replaces your current first mortgage with a bigger one. The underwriter tests the new total debt against the appraised value, not against your equity.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.18% as of November 5, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
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.
That distinction trips people up. Owing 70% does not mean you can pull out 30%. The program sets a ceiling as a share of the home’s value. You subtract what you owe, then subtract the costs of the new loan. What is left is your cash.
Say the ceiling is 80% and you owe 70%. The gap is 10% of the home’s value. Closing costs and prepaid items financed into the new loan come out of that gap. Anything still unspent is your cash.
You start with real room, and the underwriter’s job is to confirm you can carry the bigger loan.
Key Terms Defined
- Cash-out refinance: a new, larger first mortgage that pays off the old one and hands you the difference in cash.
- Rate-and-term refinance: a refinance that pays off the old loan and costs, with only a small amount of incidental cash back. Lenders also call it limited cash-out.
- LTV and CLTV: loan-to-value compares your loan to the home’s value. Combined LTV (CLTV) adds any second loans on the home to the total.
- Seasoning: the waiting period a lender wants before you can refinance, counted from the loan’s note date or from when you took title.
- Debt ratio (DTI): your total monthly debt payments divided by your gross monthly income.
- Reserves: savings left over after closing, measured in months of housing payments.
- Mortgage insurance: a policy that protects the lender when your LTV is above 80%. Under federal law you can ask to cancel it at 80% of the original value, and the servicer must end it at 78%.
The Four Tests Every Cash-Out File Faces
Every file gets measured on four things: the collateral, your credit, your income and debts, and your reserves and paperwork. At 70% owed, the collateral test is the easy one. The other three decide how smooth the file is.
Collateral. The appraisal sets the value. Your new loan, including financed costs and any second lien paid off, must fit under the program cap. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review.
Credit. The wholesale conventional programs a broker places these files with start at a 620 decision score. The automated underwriting finding governs most files. A higher score gives the file more room, and a weaker score can narrow your choices.
Income and debts. The lender adds up your new housing payment and every other monthly debt. Then it compares the total to your income. The total ratio ceiling is 50% on most automated files. Manually underwritten loans use ratios of 36% or 45%, depending on the score and reserve factors.
Reserves and documents. Cash left after closing shows you can absorb a bad month. Documents prove everything else.
Here is the part most guides skip: owing only 70% of your home’s value helps the collateral story. Low leverage does not rewrite the income story. Think of it as a good foundation under a house that still has to pass inspection.
How Underwriting Runs, Step by Step
Wholesale lenders review a cash-out file in a sequence of eight checks. Lendmire’s cash-out refinance programs page lays out the program lanes. Here is the sequence behind them.
1. Classify the purpose. The lender decides whether the file is rate-and-term or cash-out. Meaningful cash back means cash-out leverage limits and cash-out pricing apply.
2. Check the clocks. The first mortgage being paid off must meet the lender’s minimum seasoning, counted from note date to note date. You must also have been on title for the lender’s minimum period. Exceptions exist for delayed financing, inheritance and legal awards, so confirm the specifics with the lender and a qualified local professional.
3. Check occupancy and property type. A primary residence, a second home and an investment property get different caps. Unit count matters too.
4. Value the home. An appraisal sets the number. Some conventional files qualify for an appraisal waiver, but eligibility depends on the lender and the file.
5. Run credit and ratios. Automated findings review your score, your debts and your income together.
6. Check reserves. A higher debt ratio can trigger a reserve requirement. Fannie Mae’s Selling Guide on cash-out transactions ties a reserves requirement to higher debt ratios on automated files.
7. Build the loan amount. The total is your payoff, any second liens paid off, financed costs, and your cash. That sum must fit under the cap.
8. Document and decide. The lender reviews the full file and issues a decision, subject to its guidelines.
Step seven is where 70% pays off. You are not squeezing the cap. You are choosing how much of the headroom to use.
The Worked Math: Value, Ceiling, Payoff, Costs, Cash
No dollar figures are needed. Treat the home’s value as 100 and work in percentages of value. This models a one-unit primary residence at the 80% conventional cap, with a fixed 70% payoff.
| Step | Appraisal at expected value | Appraisal 5% low |
|---|---|---|
| Home value | 100 | 95 |
| Ceiling at 80% | 80 | 76 |
| Less payoff (70) | 10 left | 6 left |
Modeled assumptions, not a quote. Values are in percentage points of the expected home value.
A low appraisal hurts twice. The ceiling falls with the value, and your payoff does not change. A 5% miss on value cuts the headroom from 10 points to 6, so you give up 40% of your available cash before costs. Your 70% also becomes about 73.7% of the lower value.
Now try a two- to four-unit home. The cap is 75%, so expected headroom is 5 points. With the same 5% low appraisal, the ceiling is about 71.25 and the headroom is about 1.25 points. Costs can erase that.
Conventional programs let you finance closing costs and prepaid items into the loan. That keeps cash out of your pocket at closing, but it shrinks your net cash. The same Fannie Mae section allows financing costs, points and prepaids. Freddie Mac’s servicing guide section 4301.5 adds the six-month ownership clock and points to cash-out credit fees.
What Changes by Occupancy and Loan Type?
Occupancy sets the cap. Here is how the verified conventional figures line up.
| Property use | Maximum LTV on cash-out |
|---|---|
| One-unit primary residence | 80% |
| Two- to four-unit primary residence | 75% |
| Second home | 75% |
| Investment property | 75% |
A cash-out can be written on a primary residence, a second home or an investment property. The occupancy simply moves the cap. That is all the second-home or rental question needs here.
Across the wholesale programs Lendmire places files with, one lane goes further. It reaches 89.99% LTV with no mortgage insurance, on a thirty-year fixed loan, a primary residence and a conforming balance. It requires a 680 score and a 50% ratio ceiling. It carries its own six months of seasoning. Mortgage insurance is required above 80% on the standard agency path, and this no-mortgage-insurance lane is the exception to that rule. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
If you owe 70%, this lane matters for one reason. It can raise your ceiling from about 10 points of headroom to about 20, and the underwriter weighs that room against the stricter credit bar.
Where the General Rule Breaks
The clean rule is “owe 70%, cap at 80%.” Several named cases bend it.
- Delayed financing. If you bought with cash and now want your money back, the seasoning rules have an exception. It still prices as cash-out, as the Fannie Mae section above notes.
- Free-and-clear homes. Freddie Mac’s Guide section 4301.5 treats a new mortgage on a home you owned free and clear as cash-out.
- Buying out a co-owner. Under a written agreement, this counts as a limited cash-out transaction at both agencies, not a full cash-out.
- Texas homestead. A cash-out on a Texas homestead (a Section 50(a)(6) loan) is capped at 80% of the home’s value by the state constitution. The wholesale no-mortgage-insurance lane is not written there.
- Government-backed loans. An FHA Streamline or a VA IRRRL (the interest rate reduction refinance for VA loans) lowers your cost without cash. Neither is a cash-out path. FHA cash-out follows its own cap. A VA cash-out can reach well above the conventional caps.
- Value-limited loans. Sometimes the appraisal, not your balance, limits the loan. Lendmire’s write-up Best Cash-Out Refinance Program When the Home’s Fair Market Value Limits the Loan Amount walks through that case.
What Strengthens or Weakens Your File?
At 70% owed, you are already strong on collateral. Here is what moves the rest.
Strengthens the file:
- A score well above the program floor.
- A debt ratio comfortably under the ceiling after the new payment.
- Reserves beyond the minimum.
- A stable, documentable income history.
- A first mortgage at least 12 months old and 6 months on title.
Weakens the file:
- A high debt ratio once the larger payment is counted.
- A recent late payment or a credit event inside the agency waiting periods. These run four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu. Shorter periods may apply with documented extenuating circumstances.
- Thin reserves.
- An appraisal that comes in under your expectation.
Does low leverage offset weaker credit? Partly. It helps with collateral risk. It cannot cover a debt ratio that is already too high.
Self-employed borrowers get the same four tests. The difference is documentation. Income is built from tax returns and business records, and the lender spends more time on it.
Do Closing Costs and Payoffs Change the Debt Test?
Yes. Paying off other debts at closing can lower your monthly obligations, and that can improve the ratio. The lender counts the new housing payment in full, and it may remove paid-off debts from the calculation. The rules depend on the program and the file.
A bigger first mortgage means a bigger payment. The CFPB’s guide on using home equity notes that a cash-out may lengthen the payoff time and raise the payment. Run that new number against your income before you apply, not after.
What Documents Will You Need?
Expect to hand over a recent mortgage statement, proof of income and assets, ID, insurance details, and a payoff statement. The lender orders an appraisal and title work. Delayed-financing files also need the original settlement statement and proof of where your purchase funds came from.
Gather income documents first. They take the longest to pull together.
The Honest Tradeoffs
A cash-out replaces your current loan. You lose its original term and structure. A HELOC or home equity loan leaves the first mortgage intact, as the CFPB’s research blog on cash-out refinances explains. That difference is the whole decision for many borrowers.
The CFPB’s report on cash-out borrowers found credit scores jumped in the quarter after closing, then worsened gradually. Borrowers often used the cash to pay down card and auto debt. Debt can creep back up afterward. That is a habit question, not a loan question.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
A broker can help with the “which program” question. The best program for your situation depends on your property type, credit profile, how much cash you need, and how you document income. A broker shops several wholesale lenders and matches the scenario to a program.
Your Pre-Application Self-Check
1. Confirm your first mortgage is at least 12 months old and you have been on title six months. 2. Estimate your home’s value conservatively, then subtract 5%. 3. Take 80% of that value (75% for multi-unit homes or non-primary use) and subtract your payoff. 4. Subtract a generous allowance for closing costs and prepaids. 5. Compute your debt ratio with the new, larger payment. 6. Check your reserves against your monthly housing payment. 7. Pull your documents.
If step three leaves a thin number, a cash-out may not be worth the cost. Run it before you apply.
Frequently Asked Questions
Can I get 30% of my home’s value out if I owe 70%?
Not on a conventional loan. The cap is a share of value, and on a one-unit primary residence it is 80%. That leaves about 10% of value before costs. The no-mortgage-insurance wholesale lane reaches 89.99% for qualified primary-residence files, which gives roughly 20% of value before costs. It requires a 680 score and its own seasoning. Exact terms depend on lender and investor guidelines, credit profile, reserves, and property review.
Does a low appraisal really shrink my cash that much?
Yes, because your payoff stays fixed while the ceiling falls with the value. In the example above, a 5% low appraisal cut the headroom noticeably, and costs then come out of what is left.
Is an appraisal always required?
Often, but not on every file. Some conventional files qualify for an appraisal waiver based on the automated findings.
Does owing only 70% help me qualify with weaker credit?
It helps the collateral side only. The lender still checks the credit score, the debt ratio with the new payment, and reserves. A score under the program floor or a ratio over the ceiling can still stop the file.
How is a cash-out refinance different from a HELOC?
A cash-out replaces your first mortgage with a new one. A HELOC or home equity loan sits behind your first mortgage and leaves it unchanged. The right choice depends on whether your current loan is worth keeping.
Next Steps
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches. Program figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend.
Borrowers who owe 70% often have the most choices and the least urgency, and that usually means the best deal comes from comparing programs before picking one.
