The Quick Read: A jumbo lender sizes cash-out by running a few tests and letting the tightest one set your limit. The tests are the value the lender will count, the leverage cap for your occupancy and loan amount, the payoff of your current mortgage, and any cash cap or reserve rule. Planned work usually earns less credit than finished work. Everything is subject to lender guidelines and full file review.
Jumbo sizing is set by each lender, not by an agency. That is the single most important fact on this page. Fannie Mae and Freddie Mac write rules for loans they buy, and a jumbo loan sits above that line. So the numbers you hear about renovation loans from the agencies are a template, not the rulebook.
Jumbo cash-out estimate
Enter the value, the balance, and the cash wanted; choose the occupancy and the structure; the lanes, the payment, and the reserves follow.
Editable benchmark: 7.18% as of November 5, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo cash-out refinance quote.
Illustrative starting assumptions: a $2,000,000 home value in the jumbo range, a $1,000,000 current balance, a principal residence on a thirty-year fixed structure at the current Freddie Mac conforming 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 conforming benchmark, a market reference and not a jumbo cash-out refinance quote; a jumbo loan is priced by the lender at lock. The lanes shown are the wholesale cash-out lanes behind this page as of the snapshot date; the calculator reads each lane’s leverage, loan maximum by occupancy, cash-in-hand cap, and reserves as the lane table states them, and a Lendmire loan officer confirms the lane on the file. The cash available is the loan the lane allows less the balances paid off, before closing costs, which are not included; on most lanes a jumbo cash-out begins one dollar above the conforming limit for the county, and two lanes start at a stated dollar floor instead. The HELOC line is the line 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.
This guide walks through the sizing steps, shows how renovation and ADU plans change the math, and names the places where the general rule breaks.
What Makes a Loan Jumbo, and Who Sets the Rules?
A loan is jumbo when it starts one dollar above your county’s conforming limit. The Federal Housing Finance Agency (FHFA) sets those limits, and they change every year and vary by county. Check your county’s current figure before you plan anything.
Once a loan is outside agency eligibility, each wholesale lender writes its own matrix. Across the wholesale programs Lendmire places files with, the envelope looks like this:
- A 660 decision score is required on the headline lane.
- The loan-to-value (LTV) ceiling is 90%. Several lanes instead cap combined loan-to-value (CLTV) at 89.99%, and the remaining lanes stop at 80%.
- Loans reach $5,000,000 on the largest lanes.
- The ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lanes and 43% on the interest-only lanes. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Those are the outer edges, not what a cash-out gets. Cash-out sits at lower leverage than a purchase, and the largest lanes add a cash cap. Lendmire’s jumbo cash-out refinance program page lays out how these lanes are used for borrowers who want to pull equity from the home they live in.
Key Terms Defined
As-is value: What the appraiser says the home is worth today, before any planned work.
After-improved value (as-completed value): What the appraiser says the home will be worth once the described work is finished.
LTV: Loan-to-value, the new loan balance divided by the home’s value.
CLTV: Combined loan-to-value, which adds any second loan to the first before dividing by value.
Cash-in-hand cap: A limit on how much money you can take out at closing, set by the lender on some lanes.
Reserves: Cash or liquid assets you keep after closing, counted in months of your full housing payment.
How Does a Lender Size the Loan, Step by Step?
The lender starts with value, applies the leverage cap, subtracts what you owe, and then checks the result against every other limit. The smallest answer wins. The sequence below shows how that works.
Step 1: Classify the loan. Is it a cash-out refinance, a rate-and-term refinance, or a renovation loan with held funds? Classification drives the leverage cap. Freddie Mac defines a cash-out refinance as a mortgage with no specific restrictions on how the proceeds are used. That is the plain-cash idea jumbo lenders borrow too.
Step 2: Pick the value. A plain cash-out is sized on as-is value. A renovation structure may be sized on after-improved value. Same house, same project, different structure, different answer.
Step 3: Apply the leverage cap. Cash-out gets lower leverage than purchase. Occupancy matters too: primary residence, second home and investment occupancy each carry lane-specific leverage. If you live in the home, you sit in the strongest position.
Step 4: Subtract the payoff. Your current first mortgage, plus any liens that must be cleared, comes off the top.
Step 5: Subtract costs. Closing costs can be paid at the table or rolled into the balance. Either way, they shrink the cash that reaches your project.
Step 6: Test against the other limits. These include the loan ceiling, any cash cap on the lane, reserves, the ratio ceiling and the appraisal threshold.
The result is the net cash. Write that sequence on a sheet of paper: value times leverage cap, minus payoff, minus costs. Then ask which limit is the tightest. That one is your binding constraint.
Which Value Counts: As-Is or After-Improved?
On a standard jumbo cash-out, the lender counts as-is value. Credit for the finished project comes only on structures built for it, and those vary by lender. So planned work often earns nothing in the sizing.
This is where borrowers get surprised. They assume a $200-per-square-foot addition adds the same value on paper the day the permit is pulled. It does not. Until the work exists, an appraiser has little to measure.
The agency world shows the contrast clearly. Fannie Mae’s HomeStyle Renovation page says the product is available only for a purchase or a limited cash-out refinance. It sizes renovation funds on the as-completed appraised value, and for a refinance it caps renovation funds at 75% of that value. The fact sheet adds that refinance LTV is measured against the as-completed value. Those are conforming rules. They do not carry over to a jumbo balance.
What jumbo lenders often borrow from that template:
- An as-completed appraisal that values the home as if the work were done.
- Renovation money held back and released against progress.
- A cap on how much of the loan can be renovation money.
What they set on their own: every number. If a renovation structure exists at your loan size, ask for its matrix. If none exists, the standard cash-out is your path, and it counts the home as it stands.
Three Ways the Same Project Sizes Differently
These scenarios use percentages and plain words only. Treat them as modeled assumptions, not quotes.
Scenario A: Finish first, then refinance. A homeowner completes a kitchen and bath remodel using savings or a short-term line, then applies for a cash-out refinance. The appraiser sees finished work. As-is value now includes it. The cash-out sizes against a higher value, and the proceeds replenish the savings. Cleanest appraisal, but you front the cost.
Scenario B: Refinance first, then build. A homeowner pulls cash at the as-is value and spends it on the project. Nothing about the plan raises the value in the sizing. If the equity at the lane’s cap does not cover the budget, the project stalls. Simple to qualify, but the budget has to fit the as-is number.
Scenario C: A renovation structure with held funds. If a lender offers one at your loan size, the loan may be sized on after-improved value, with funds escrowed and released as work is verified. More documents, more steps, and often more reach. It is also the least common option in jumbo.
| Approach | Value used | Cash timing | Best fit |
|---|---|---|---|
| Finish first, then refinance | Finished as-is | After work | You can front the cost |
| Refinance first, then build | Current as-is | At closing | Budget fits current equity |
| Renovation structure | After-improved | Released in draws | Work adds major value |
Honestly, the choice between A and B is a toss-up for many homeowners. A gives better sizing. B gives certainty that the cash exists before the contractor starts.
How Does an ADU Change the Sizing?
An ADU changes the value story more than it changes the sizing rules. Lenders still count as-is value on a standard cash-out, so an unbuilt ADU adds nothing. A finished, permitted ADU can add to the appraisal, but it is valued differently than the main house, and fewer comparable sales exist.
The agency definition is a useful guide to what lenders think of as a real ADU. Under Fannie Mae’s special property rules, an ADU needs living, sleeping, cooking and bathroom facilities. It must sit on the same parcel as the primary one-unit home and be smaller than it. Only one ADU is allowed per parcel. A space reachable only through the main house does not count. Zoning and appraisal requirements must also be met.
Rent from the ADU is a separate question. In the conforming world, rental income from your own residence generally cannot be used to qualify, with ADUs as a named exception. Fannie Mae’s rental income rule for the subject property limits the credit to an existing ADU, counts one ADU only, and caps the income at 30% of total qualifying income. A plan to build an ADU and count its future rent generally does not work there. Whether a jumbo lender counts ADU rent at all is lender-specific. Do not assume it does.
Practical takeaway: qualify on your own income and reserves, and treat any ADU rent as a bonus you confirm in writing with the lender.
Where the General Rule Breaks
- A cash cap on the largest lanes. Two lanes limit the cash you can take out regardless of equity. Plenty of equity, tight cap, and the cap is your binding constraint.
- The loan ceiling. Loans reach $5,000,000 on the largest lanes. A smaller lane ends sooner.
- Two appraisals. Above a lane’s threshold amount, lenders ask for two appraisals. The lower value generally governs, so a project priced on the higher one can fall short.
- Reserves that rise with the amount. Reserves are counted in months of the full payment. A larger loan needs more months, so a borrower with plenty of equity but thin liquid savings can get capped by reserves.
- Occupancy. Primary, second-home and investment occupancy each carry their own leverage. Occupancy decides the leverage, so a primary residence gets the most room.
- Condos. Non-warrantable condominiums are accepted on two lanes only.
- State homestead rules. Some states define “cash-out” differently from the agencies. As one law firm’s note on Texas shows, a refinance the agencies call rate-and-term can still be treated as a home-equity loan under state law. Ask how your state treats it.
- Limited cash-out is not zero cash. The agency version allows small cash back, capped at the greater of 1% of the new loan or $2,000. Jumbo lanes draw their own line between limited and full cash-out.
One more practitioner note. Borrowers watch the LTV and forget the reserves or the cash cap. Find the binding constraint before you sign a contractor.
What Does the Lender Want to See in the File?
- Plans and specifications for the work.
- A contractor bid or signed contract.
- Permits, or proof that they are obtainable.
- Evidence that the project is permanently affixed and code-compliant.
- Insurance that covers the completed value of the home, which Fannie Mae’s HomeStyle page requires on its own program.
- On a held-funds structure, a completion certificate or appraisal update at the end.
Renovation funds on agency products sit in a custodial account and are released against progress, with the lender monitoring the work. Do-it-yourself labor is allowed on that product only at lender discretion and is capped at 10% of as-completed value. A jumbo lender may be stricter. Expect the same logic: they want proof the money becomes value.
Build a contingency into your budget. If your budget needs exactly the maximum cash, one cost overrun leaves you short, and the loan cannot grow after closing.
Cash-Out, HELOC or Renovation Loan?
A cash-out refinance replaces your entire first mortgage with a larger one. You get one loan and one payment, but you reset the whole balance, not only the new money. That reset is the tradeoff to weigh.
The CFPB’s HELOC booklet notes that a home equity line’s payment can vary and that lenders can freeze or reduce a line. A refinance trades that variability for a bigger first lien.
| Option | What changes | Main upside | Main catch |
|---|---|---|---|
| Jumbo cash-out | Whole first mortgage | One loan, funds at closing | Costs on the full balance |
| HELOC or second lien | Adds a separate loan | Keeps your first mortgage | Variable terms, lender can freeze |
| Renovation structure | Whole loan, funds held | Sized on finished value | More documents, fewer options |
A second lien beside your existing first mortgage is a different tool than jumbo cash-out, and it deserves its own comparison.
What Does It Cost, and What Reaches the Project?
Closing costs apply to the entire new balance, not only the cash you take out. They can be paid at closing or financed. Either way, they reduce the money available for the work.
Watch for this: a lower “cash to close” does not mean lower costs. Costs may be netted from proceeds. The Loan Estimate and Closing Disclosure show total closing costs and cash to close as separate numbers, so compare both across lenders.
The CFPB’s Your Home Loan Toolkit advises collecting Loan Estimates from several lenders. It also lists an appraisal coming in higher or lower as a common reason a Loan Estimate gets revised. That matters here, because your appraisal is the first number the whole sizing rests on.
Two more cautions. Your current mortgage terms go away in a refinance, so weigh what you are replacing. And the toolkit warns that home values can fall, so do not count on refinancing or selling later to bail out a budget. Cash-out money is borrowed money.
Frequently Asked Questions
Does a jumbo lender count the value of a renovation I have not built yet?
Usually not on a standard cash-out, which sizes on as-is value. Some structures size on after-improved value with funds held and released in draws. Those are lender-specific and less common at jumbo loan sizes, so ask whether one exists for your amount.
Will a jumbo lender count rent from an ADU to help me qualify?
It depends on the lender. Agency rules count only an existing ADU and cap that income at 30% of qualifying income. A planned ADU’s future rent generally does not count. Do not assume a jumbo lender follows the agency rule either way.
Why can’t I use a Fannie Mae or Freddie Mac renovation loan?
Those products stay within conforming limits. A balance above your county’s limit is jumbo and outside agency eligibility. The agency rules still help you understand the concepts, such as-completed value and held funds.
Will I need two appraisals?
Possibly. The lower value generally governs, so build that into your budget.
What usually limits my cash-out the most?
It varies by file. It can be the leverage cap, the loan ceiling, a cash cap on the largest lanes, or reserves. Calculate each one and find the tightest. A broker who shops several wholesale lenders can match your scenario to the lane whose limits fit.
What to Ask Before You Commit
- Does this lender size on as-is value or after-improved value?
- Is there a cash-in-hand cap on this lane?
- How many months of reserves does my loan amount require?
- Do I need one appraisal or two?
- Does the lender count ADU rent, and for which loan structures?
- Which documents prove the project, and who releases funds?
Which program is best for your situation depends on your property type, credit profile, leverage need and documentation. Program figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend.
