Jumbo Loans

A jumbo loan is a loan-size problem before it is a rate problem.

A mortgage is jumbo when the loan amount exceeds the conforming limit for the county the property sits in. That single threshold changes who can buy the loan, which changes the documentation, the reserve expectation, and how widely pricing varies between one investor and the next.

Get a second opinion on a jumbo scenario

When the jumbo conversation starts

Your loan amount is above the conforming limit for your county
You are close enough to the limit that a larger down payment could avoid jumbo entirely
Your income is documented through a business, K-1s, or assets rather than a W-2
You are holding more than one jumbo quote and the numbers are far apart

What Sets The Threshold

The limit is set per county, and it changes every year.

The Federal Housing Finance Agency publishes conforming loan limits annually, with higher limits in designated high-cost counties. Your loan is conforming up to that number and jumbo above it. Because the limit moves and is location-specific, whether a purchase needs jumbo financing is a question about the county and the loan amount, not about the price of the house on its own.

Just over the line

When the loan amount lands slightly above the county limit, increasing the down payment or restructuring with a second lien can keep the first mortgage conforming. Worth pricing both ways before assuming jumbo.

Clearly above the line

Well above the limit, jumbo is the only lane and the question becomes which investors will look at the file. Portfolio lenders and non-agency investors underwrite the same borrower differently.

High-balance territory

Some counties carry a raised limit. A loan that would be jumbo elsewhere can be high-balance conforming there, which is a different product with different pricing.

What Lenders Commonly Ask For

Jumbo underwriting is guideline-by-guideline, not a single rulebook.

Conforming loans are underwritten to one set of agency rules. Jumbo loans are not: each investor writes its own guidelines, so two lenders can reach opposite conclusions on the same file. The items below are what jumbo programs commonly ask for. None of them is a universal requirement, and none is a commitment to lend.

Credit

Jumbo programs generally start at higher credit thresholds than conforming, and the tier breaks are steeper.

Down payment

Commonly 10% to 20%, with more asked for on second homes, investment property, or larger loan amounts.

Reserves

Months of payments held after closing. This is often the item that decides a jumbo file, and it varies more between investors than anything else.

Income documentation

Full tax returns are typical. Bank statement, P&L, and asset-based routes exist and sit in the non-QM product family.

Appraisal

Two appraisals are still required by some investors above certain loan amounts. Budget for the possibility.

Property type

Condominiums, non-warrantable projects, unique properties, and large acreage narrow the investor list before pricing is even discussed.

Why A Second Opinion Matters Here

Jumbo pricing spreads between investors are wider than conforming.

Conforming loans are priced against a liquid secondary market, so lender-to-lender differences are relatively narrow. Jumbo loans are held or sold to a smaller set of buyers with their own appetites, and the spread between them on an identical file is materially wider. That makes a jumbo quote hard to read in isolation: without a second quote there is nothing to read it against. A Loan Estimate review costs nothing and does not require a credit pull.

Next Step

Bring the loan amount, the county, and any quote you already have.

Send the purchase price or estimated value, the loan amount, the county, your credit range, how your income is documented, and what you hold after closing. That is enough to say whether the file is jumbo at all and which structures are worth pricing.
