The Quick Read: A finished basement gets valued, but it does not count as living area. The appraiser reports it on its own line as below-grade finished area and adjusts for it against comparable sales. That value feeds the loan-to-value cap, so it decides how much cash you can take. If the basement is mismeasured or under-credited, you can ask for a reconsideration of value.
Why the Appraisal Sets Your Cash
A cash-out refinance replaces your current mortgage with a larger one and pays you the difference. The lender caps the new loan as a percentage of appraised value. On conventional loans, that cap is 80% LTV on a one-unit primary residence, and 75% on two- to four-unit primary residences, second homes and investment property. Occupancy sets the leverage. Every figure here varies by lender and program, and guidelines, property type, leverage, and credit profile all apply.
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.
So the appraised value is the denominator. If the appraiser credits your basement less than you expected, the maximum loan falls. The cash falls with it, because your existing payoff stays the same. The first mortgage also has to be at least 12 months old, counted note date to note date, and a borrower must have been on title for 6 months, with delayed-financing, inheritance and legal-award exceptions.

Key Terms Defined
Above-grade finished area: Finished living space on levels entirely at or above ground level. This is the number that drives most of a home’s value.
Below-grade finished area: Finished space on any level that sits partly or wholly below ground level. Fannie Mae now uses this term in place of “basement.”.
Nonstandard finished area: Finished space with a low ceiling or reached through unfinished space. It is reported separately.
Comparable sale (“comp”): A recent nearby sale the appraiser uses to estimate your value.
Reconsideration of value (ROV): A formal request that the lender ask the appraiser to review the value with new facts.
How the Appraiser Treats a Finished Basement
Fannie Mae’s Selling Guide section B4-1.3-05 requires appraisers to measure to the ANSI Z765-2021 standard. That standard covers finished and unfinished space, above and below grade. Here is the sequence on a typical visit:
1. The appraiser measures the house and sorts every area into above-grade finished, below-grade finished, nonstandard finished or unfinished.
2. The appraiser sketches the floor plan so each category is separate. Lenders review that sketch for exactly this split.
3. Below-grade finished area goes on its own line of the sales comparison grid.
4. The appraiser compares above-grade space with above-grade space and below-grade with below-grade, using sales that have similar finished lower levels.
5. The adjustment comes from the market. No rule sets a per-square-foot value for a basement.
6. The final value becomes the denominator for your cash-out LTV cap.
Not counted as living area does not mean zero value. It means the space is priced through an adjustment rather than added to the square footage.
What Makes a Basement “Finished”?
Fannie Mae’s ANSI FAQ says a level is partly or wholly below grade if any portion of its walls is not entirely at or above ground level. It also says finished areas need a ceiling height of at least 7 feet.
Four things shape the result:
- Classification. Above-grade, below-grade or nonstandard.
- Ceiling height. Space under 7 feet gets reported separately.
- Access. Finished interior stairs are different from a route through an unfinished utility room.
- Condition and quality. The appraiser rates the finish, like any other room.
Fannie Mae’s June 2025 Appraiser Update retired the older terms “gross living area” and “basement.” If your appraisal or a loan officer uses the old words, they mean the same thing.
Where the General Rule Breaks
Several situations change how the basement is handled.
Walk-out basements. A walk-out with finished rooms is still below grade. Window area and finish quality do not change that, so it stays out of above-grade square footage and room count.
Unpermitted finishing. If the appraiser spots an addition without a required permit, Fannie Mae’s appraisal FAQ calls for comment on its quality and any effect on market value. It does not set a blanket exclusion. In practice, the result varies by appraiser and by what the comps show. Fannie Mae also only buys loans where improvements are a legal use or a grandfathered one.
A rental unit or in-law suite. A separate unit in the basement raises zoning and legal-use questions. Talk to your loan officer before ordering an appraisal.
Free-and-clear homes. A cash-out on a home with no mortgage is still a cash-out. Borrower-on-title rules and the delayed-financing exception apply.
Streamlines. The FHA Streamline and VA IRRRL start from an existing government loan, need no new appraisal, and do not produce meaningful cash. A basement never enters those values. The VA IRRRL carries a 0.5% funding fee unless exempt, and both need a net tangible benefit. A VA or FHA cash-out is a different loan and does need an appraisal.
| Basement situation | How it is reported | Likely effect |
|---|---|---|
| Permitted, finished, 7-ft ceiling | Below-grade finished area | Adjusted against similar comps |
| Walk-out, finished | Below-grade finished area | Still below grade; may earn a stronger adjustment |
| Low ceiling or through unfinished space | Nonstandard finished area | Reported separately |
| Unpermitted finishing | Appraiser comments on quality and value | Varies by appraiser and comps |
| Separate rental unit | Legal-use question | Ask your loan officer first |
Why Square Footage Numbers Disagree
Your listing, county record and appraisal can show three different figures. The appraiser measures to ANSI, and records often lump basement space into the total. A mismatch is not an error by default. If you see one, ask the lender to have it explained in the report.
A Worked Example, Without Dollars
Take a home where you expect the basement to add meaningful value. Suppose the appraiser finds comps with finished lower levels that are thin, and credits the space modestly. The appraised value lands below your estimate. At 80% LTV on a one-unit primary residence, the new loan ceiling drops with it. Your payoff does not move. The difference between the two, what you can take as cash, shrinks by 80% of the value gap, because the ceiling falls by that share while the payoff stays fixed. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Now flip it. If three nearby sales have similar finished basements, the appraiser has stronger comparables for the adjustment, so the credit given to your basement is easier to support in the report.
If the Value Comes In Low
You can challenge it. The CFPB describes the reconsideration of value process: you point to factual errors, omissions or inadequate comparables. Undervaluation can block access to equity, which is why the step exists.
A good packet includes:
- Recent nearby sales with similar finished basements.
- The basement’s measurements, ceiling height and finished-stair access.
- Permit records, if the work was permitted.
- A note on any measurement the report got wrong.
Route this through the lender’s formal channel. Lenders must not pressure an appraiser on value, so a loan officer cannot simply call and ask for a higher number. Ask early whether the lender has an ROV process and how to start it.
Your Right to the Appraisal Copy
Under the CFPB’s ECOA valuations rule guide, you are entitled to a copy of the appraisal at no added cost. Without a waiver, you must receive it at least three business days before closing. You pay for the appraisal even if the loan does not close, but you still get the copy.
Preparing for Appraisal Day
- Gather permits and a log of finishing work.
- Make sure the basement is accessible and well lit, with stairs clear.
- Note ceiling height, egress windows and heat sources.
- Fix visible moisture or safety issues first.
- Pull a short list of nearby sales with finished lower levels.
Space that is damp, dark or poorly connected to the rest of the home may add little, even if you spent heavily to finish it.
What the Decision Looks Like
Ask one question: does the equity I can reach, at the cap, still make the cash-out worth it? If the basement is carrying part of your value case, test the downside first. If you need real cash, the appraised value rules. A limited cash-out refinance is a different transaction: it pays off your existing mortgage and returns only incidental cash, so it does not suit someone who wants to pull equity out. The FHA and VA streamlines, for existing FHA and VA loans, skip the appraisal but are not cash-out loans either.
A wholesale lane also exists that 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, with its own six months of seasoning. It is the one exception to the rule that mortgage insurance applies above 80%. It is not written in Texas, where a homestead cash-out is capped at 80% of value by the state constitution.
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.
Frequently Asked Questions
Does my finished basement count toward my home’s square footage?
No. Under Fannie Mae’s standard, below-grade finished area is reported separately from above-grade living area. It still earns value through a comparison adjustment, so it can raise the appraisal without adding to the square footage.
Does a walk-out basement with big windows count as above grade?
No. Fannie Mae says window area and finish quality do not change the classification. If any part of the level is below grade, it is reported as below-grade finished area.
Will an unpermitted basement be valued at zero?
Not automatically. Fannie Mae’s guidance asks the appraiser to comment on quality and any effect on market value. The outcome depends on the appraiser and the comparable sales.
Can I challenge a low appraisal?
Yes. You can request a reconsideration of value through the lender, supplying comparable sales or correcting factual errors. Ask the lender how its process works.
Does every refinance need an appraisal?
No. The FHA Streamline and VA IRRRL generally need none, but neither delivers meaningful cash. A conventional cash-out normally needs a full appraisal.
