The Quick Read: Your maximum loan is the lowest result of three tests, and income is only one of them. The income test caps the monthly payment your pay can carry. The cash test checks what is left in the bank after the down payment and closing costs. The value test looks at the appraisal and your down payment. Whichever test gives the smallest number sets the ceiling, and on many high-earner files that is the cash test, not the paycheck.
What Does “Supports” Actually Mean?
A salary does not convert to a loan size by a fixed multiple. No such rule exists for jumbo loans. Each lender sets its own ceiling, and the file is sized by whichever limit bites first.
Jumbo payment estimate
The starting figures are an example price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo loan quote.
Illustrative starting assumptions: a $1,000,000 price in the jumbo range, ten percent down on the top-leverage lane, 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 loan quote; jumbo rates are set by the lender and the lane at lock and differ from the conforming benchmark. An adjustable-rate scenario is shown at the benchmark for the whole term; the rate after the initial period is unknown. Reserve months and appraisal counts follow the lane sheet for the amount band; the automated finding may require more. Taxes, insurance and dues are editable estimates; closing costs are not included. On most lanes the conforming limit for the county decides whether a loan is jumbo at all; two lanes start at a stated dollar floor instead. Licensed in sixteen states for consumer mortgages.
Here is how it works across the wholesale programs Lendmire places files with. There are three separate caps:
- Income cap. Total monthly debts, including the new housing payment, must fit under a ratio ceiling set against gross monthly income.
- Cash cap. After the down payment and closing costs come out, enough liquid money must remain to cover a required number of months of the full payment.
- Value cap. The loan cannot exceed the program’s leverage limit against the appraised value or price, whichever is lower.
Say two buyers earn the same salary. One has deep savings and little debt. The other has thin savings and a car loan. Their loan ceilings can differ by a wide margin. Same pay, different file.
Key takeaways
- Jumbo means the loan amount is above the county’s conforming limit, not that the price is high.
- The jumbo loan programs Lendmire arranges run to 90% leverage on some lanes and to $5,000,000 on the largest, with a 660 decision score on the headline lane. All of it is subject to lender guidelines and full file review.
- The ratio ceiling is 50% on the fixed-rate lanes, 45% on the adjustable lanes and 43% on the interest-only lanes.
- Reserves are counted after closing, in months of the full payment, and they rise with the loan amount.
- Not every dollar of W-2 pay counts, and not every dollar of savings counts.
Where Jumbo Starts (and Why It Is a County Question)
A jumbo loan begins one dollar above your county’s conforming limit. It is the loan amount that crosses the line, not the purchase price. A large down payment can pull a high-priced home back under the limit.
The limit differs by place. FHFA’s conforming loan limit addendum sets one baseline for most of the country. In high-cost areas the local limit rises to 115% of the local median home value, capped at 150% of the baseline. Use FHFA’s county lookup for your own number. It changes yearly, so a figure you saw last year may be stale.
Fannie Mae and Freddie Mac cannot buy loans above the limit. That is why jumbo lenders write their own rules for ratios, reserves and appraisals. Lendmire’s jumbo loan programs are built that way too: wholesale lenders set the guidelines, and the broker matches the file to the lane that fits.
Step One: Turn W-2 Pay Into Qualifying Income
Lenders work from gross monthly income. For a salaried borrower, that is annual base pay divided by 12.
Base pay is the easy part. Bonus, commission and overtime are harder. They count only when they look stable. The usual test is a history of at least 12 months, and two years is better. A lender reviews the trend, too. Rising or flat variable pay is usable. Falling pay may be cut back or left out.
Documentation follows the same logic. For variable pay, a lender typically wants a verification of employment, or a recent pay stub plus two years of W-2s. Fannie Mae’s Selling Guide on bonus, commission and overtime lays out that conforming standard. Jumbo lenders often ask for the longer paper trail even where the agencies have relaxed it.
Picture a buyer whose pay is mostly bonus. A base salary of 100 units and a bonus of 60 units sounds like 160. If the bonus has a two-year average and a flat trend, a lender may count most of it. If the bonus is new or has dropped, the lender may count only the base. The loan ceiling moves with that call.
Step Two: Run the Income Test
The income test is a ratio. Add up all monthly debts and divide by gross monthly income. The result is the debt-to-income ratio, or DTI.
The debts counted are:
1. The full new housing payment: principal, interest, property taxes, homeowners insurance and any association dues.
2. Car loans, student loans, credit card minimums and other recurring debts.
3. Alimony or child support, where it applies.
Installment debts with only a few payments left are often excluded. Ask your loan officer where the cutoff sits.
The jumbo lanes Lendmire works with set the ceiling by structure: 50% on the fixed lanes, 45% on the adjustable lanes and 43% on the interest-only lanes. Those are program limits and a file may be held to less.
Here is the math, with income indexed to 100 so no dollars are involved. Call gross monthly income 100 units. At a 50% ceiling, total monthly debts can reach 50 units. If other debts use 10 units, the housing payment has room for up to 40. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. The same buyer gets a smaller answer on a different structure.
Property taxes, insurance and dues all sit inside that payment. A home in a high-tax county or an association with big dues eats room that principal and interest would otherwise use. That is why two buyers with the same price get different loan sizes.
On federal rules. The old 43% cap on General QM loans is gone. The CFPB’s General QM final rule replaced it with a price-based test. Lenders still have to consider DTI or residual income, though, and jumbo investors set their own ratio limits. So the ratio ceiling you meet comes from the lender, not from a federal number.
Step Three: Run the Cash Test (This Is Where Files Shrink)
Reserves are what is left after closing. The test is simple, and it catches many high earners off guard.
Fannie Mae’s Selling Guide defines liquid reserves as liquid or near-liquid assets available after closing. The jumbo programs follow the same idea. They measure reserves in months of the full payment, and the months rise as the loan amount rises. Two things happen at once on a larger loan: the payment gets bigger, and the number of months required goes up. The cash needed grows faster than the loan.
The sequence runs like this:
1. Start with total verified liquid assets.
2. Subtract the down payment.
3. Subtract closing costs and prepaid items.
4. Compare what is left to the reserve requirement for that loan size. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Say you hold 100 units of verified assets. A down payment takes 30 and closing costs take 4. You have 66 left. If the lane asks for a number of months of payment that totals 70 units on your loan size, you are short. You then have three choices: a smaller loan, a smaller down payment on a lane that allows more leverage, or more verified assets.
What counts as an asset? Checking, savings, brokerage accounts, vested retirement funds and the cash value of life insurance generally count, though lenders may discount retirement and market-based accounts. Unvested stock, unvested options, personal loans and cash pulled out of the home you are financing do not count. Gifts may help with funds, but jumbo lenders often restrict them. Ask early.
One more catch. Every dollar added to the down payment is a dollar removed from reserves. A bigger down payment lowers the loan, which lowers the reserve requirement, but it also drains the account the requirement is measured against. The best balance depends on the lane. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Which Test Binds? Four Sample Borrowers
These are illustrations, not quotes. Each row changes the mix of income, debts and savings, so read the rows as different files, not as one buyer with one paycheck.
| Profile | Income test | Cash test | What binds |
|---|---|---|---|
| High income, deep savings | Strong | Strong | Income or value |
| High income, thin savings | Strong | Weak | Cash |
| High income, heavy debts | Weak | Strong | Income |
| Moderate income, deep savings | Moderate | Strong | Income |
What raises the ceiling in each case:
- Deep savings, high income: a lane with higher leverage, or a larger down payment to cut the loan amount.
- Thin savings: more documented assets, a smaller down payment where the lane allows it, or a smaller loan.
- Heavy debts: pay off installment loans or cards before the file goes in. This often adds more room than a raise would.
- Moderate income: a fixed lane with the 50% ceiling, instead of the interest-only lane at 43%.
On many high-earner files, thin liquidity is the surprise. The paycheck is large, but wealth is tied up in unvested stock, a business, or the home being sold. Lenders see none of that as reserves.
Where the Rules Bend or Break
RSUs and equity pay. Restricted stock units can count as income once they have vested and been distributed. The stock generally must be publicly traded, with a vesting schedule and brokerage statements, and about 24 months of history is typical. Unvested units never count as reserves. A tech salary that looks huge on paper can shrink when only the vested piece is used.
A new job. A short work history can still work if other strengths offset it, such as strong credit, deep reserves and the same line of work. Expect more documentation.
Declining bonus. A falling trend can disqualify that income entirely.
Debts that surface late. If a new debt shows up or income drops before closing, the lender can re-run the file. Fannie Mae’s guidance on DTI notes that an increase in recalculated DTI can make a loan ineligible. Do not open a card or finance a car mid-process.
Occupancy. Primary homes get the most favorable treatment. A second home or investment property is handled at lane-specific leverage. Occupancy decides the leverage, so say what you plan on day one.
Cash-out. A cash-out refinance runs at lower leverage than a purchase, with a cash cap on the largest lanes. Cash pulled from the home cannot refill reserves. For that side of the question, see Lendmire’s piece How Much a Jumbo Cash-Out Nets a W-2 Homeowner After Closing Costs.
Large loans. On bigger amounts, a lane may call for two appraisals above its threshold amount. A condo that is not warrantable fits only on certain lanes. Both can narrow the field.
Key Terms Defined
Jumbo loan: a mortgage above the county’s conforming limit, which Fannie Mae and Freddie Mac cannot buy.
DTI (debt-to-income ratio): total monthly debts divided by gross monthly income.
Reserves: liquid assets left after the down payment and closing costs, measured in months of the full payment.
PITIA: principal, interest, taxes, insurance and association dues, the full housing payment.
CLTV: combined loan-to-value, which adds any second loan to the first before dividing by value.
Decision score: the credit score a lender uses to price and approve the file.
How to Raise Your Ceiling, in Order of Impact
1. Pay off installment debts and cards. This helps the income test directly.
2. Move assets into verified accounts early. Statements, large-deposit explanations and seasoning take time to document.
3. Document variable pay fully. Two years of W-2s and a clear bonus history turn “maybe” income into counted income.
4. Choose the structure on purpose. A fixed lane carries the 50% ceiling. An interest-only lane carries 43%.
5. Balance down payment and reserves. Adding down payment trims the loan but shrinks cash left over.
6. Check the county limit. A bigger down payment may bring the loan under the conforming line and out of jumbo territory.
Documents to Gather for a W-2 File
- Recent pay stubs and the last two years of W-2s
- Verification of employment, plus bonus or RSU history if relevant
- Two months of statements on every asset account
- Brokerage statements and vesting schedules for stock pay
- A list of every debt, with balances
- Homeowners insurance and association dues information for the target home
This is a planning estimate, not a pre-approval. Final numbers depend on credit, the appraisal and what the lender verifies. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Frequently Asked Questions
Is there a standard multiple of income for a jumbo loan?
No. No federal rule sets one. Each lender caps total debts against gross income, then checks reserves and leverage. The result varies with your debts, taxes, insurance and savings.
Can a high income alone get me a big jumbo loan?
Not by itself. The income test is one of three, and reserves or leverage may bind first. A strong salary with thin liquid savings often hits the cash cap before the income cap.
Do bonuses and RSUs count?
Often, once they show stability. Bonus pay generally needs a history of 12 months or more and a steady or rising trend. RSUs usually count only after vesting and distribution, with brokerage records. Unvested units do not count as income or reserves.
Do retirement accounts count as reserves?
Vested retirement funds generally can, though some lenders discount them. Unvested funds, personal loans and cash-out proceeds from the home being financed do not count. Ask the lender how it treats each account type.
Can a bigger down payment turn a jumbo into a conforming loan?
Sometimes. Jumbo status depends on the loan amount against the county limit, not the price. If a larger down payment brings the loan to or under that limit, conforming rules apply instead. Check the current county limit with FHFA.
