Programme
Jumbo Loan
Above the conforming limit, so the guidelines are the lender's own rather than a published one.
A jumbo loan is defined by one thing only: it is larger than the conforming loan limit for its county and unit count, so Fannie Mae and Freddie Mac cannot buy it. Everything else about it follows from that. Because no agency will take the loan, the lender either keeps it or sells it to a private investor, and the underwriting rules are that investor's rather than a public selling guide's. It is not a harder loan because it is bigger; it is a different loan because nobody is standing behind it.
- Above the county conforming limit
- Not sold to Fannie Mae or Freddie Mac
- Guidelines set by the lender or investor
- Ability-to-repay rules still apply

What it gives you
One loan instead of two
The alternative to a jumbo loan is often a conforming first mortgage with a second lien stacked on top, at a higher rate and its own closing costs. A single jumbo loan is usually simpler and frequently cheaper than the combination.
A human being reads the file
Because it is not going into an automated agency box, a jumbo underwriter can weigh a strong file as a whole — assets, reserves, a long earnings record — rather than fail it on one guideline line. Discretion cuts both ways, but here it usually helps a strong borrower.
The structures are more varied
Portfolio lenders will write terms and features an agency loan cannot accommodate, because they are keeping the risk. That flexibility is genuinely useful for complex income, asset-based qualification, or unusual properties.
The property may be a home, a second home or an investment
There is no occupancy requirement inherent in the product, unlike FHA, VA and USDA. The investor sets the terms for each, and second homes and investment properties are ordinary business here.

What this programme costs you
Every programme buys you something by charging you something else. This is the half a brochure leaves out, and it is the half that decides whether the programme is right for you.
- Trade-off 01
There is no published rulebook to appeal to
On a conforming loan you can read the selling guide and see the requirement in black and white. On a jumbo loan, the guideline is a private credit policy. That has two consequences: a decline at one lender genuinely does not mean a decline everywhere, and equally there is nothing you can point to when a condition seems arbitrary. Shop more than one lender, and treat the guidelines you are quoted as that lender's rather than the market's.
- Trade-off 02
The reserve requirement is the one that catches people
Jumbo investors commonly require months of the full housing payment to be held in reserve after closing — money that must exist, be documented, and still be there when the file is approved. A borrower who was planning to put every available dollar into the down payment discovers late that the down payment itself has made them ineligible. Find out the reserve requirement before you decide how much to put down.
- Trade-off 03
The whole bar is higher, everywhere in the file
Larger down payment, lower maximum debt ratio, stronger credit, more documentation, and sometimes a second appraisal on a large loan. Each requirement is reasonable on its own; together they mean a file that would sail through a conforming approval can need real work.
- Trade-off 04
Fewer buyers means less liquidity when you want to move
The pool of investors for jumbo paper is far smaller than the agency market and it contracts when credit tightens. That shows up as products being withdrawn, guidelines changing mid-application, and refinance options being thinner exactly when the market is stressed.

The published rules, and where they come from
These are rules, not prices. This site publishes no rates, so what follows is the part of the programme that is written down somewhere a third party can check.
| Rule | What it says | Source |
|---|---|---|
| What makes a loan jumbo | A loan amount above the conforming loan limit for the county and unit count. FHFA sets the limits each year; they vary considerably by county, and higher limits apply in designated high-cost areas and in Alaska, Hawaii, Guam and the US Virgin Islands. Look up the limit where you are buying — do not rely on a single national figure. | 12 U.S.C. 4542; FHFA annual Conforming Loan Limit Values |
| Who ends up owning it | Not Fannie Mae or Freddie Mac — a loan above the limit is ineligible for sale to them. It is kept by the lender or sold to a private investor, and that party writes the credit policy. | Fannie Mae Selling Guide B2-1.5-01; Freddie Mac Seller/Servicer Guide 4203.3 |
| Where the guidelines come from | There is no public minimum credit score, down payment, debt ratio or reserve requirement for a jumbo loan. Each is set by the lender or investor who will hold it, which is why they differ between lenders and can change without notice. | No federal or agency programme guide exists for jumbo lending |
| Ability to repay | Regulation Z's ability-to-repay rule applies to a jumbo loan on a dwelling exactly as it does to any other closed-end consumer mortgage. Whether the loan is also a Qualified Mortgage turns on the general QM standard, including its price-based threshold. | 12 CFR 1026.43(c) and (e)(2) |
| Mortgage insurance | Most jumbo loans are written at a low enough loan-to-value to avoid it. Where private mortgage insurance is used on a principal residence, the Homeowners Protection Act governs its cancellation on the same 80% and 78% points as any other loan. | Homeowners Protection Act of 1998, 12 U.S.C. 4902 |
| Escrow accounts | A jumbo loan that is a higher-priced mortgage loan must carry an escrow account for taxes and insurance for at least five years, like any other. | 12 CFR 1026.35(b) |
Floor one
Who it fits
The usual guidelines. Every one of them is a starting point that an underwriter reads against the whole file, so treat a line you miss as a conversation rather than a closed door.
- A loan amount above the conforming limit for that county and unit count — look yours up rather than using a national figure
- Credit, down payment and reserve requirements set by the lender or investor, not by a public guideline
- Post-closing reserves, often measured in months of the full housing payment
- Fully documented income and assets; complex income usually means more paperwork, not less
- An appraisal, and on larger loans sometimes a second one
- Ability to repay must still be established under Regulation Z
Ground floor
How it goes, top to bottom
Look up the conforming limit for the county you are buying in
FHFA sets the limits annually and they vary by county and by unit count. The same loan amount can be conforming in one county and jumbo in the next one, which changes the rulebook and the pricing.
Ask each lender for its reserve requirement in writing, first
It is the requirement most likely to change how much you put down, and the one least likely to be volunteered early.
Shop more than one lender, properly
Because the guidelines are private, they genuinely differ. Two lenders can reach opposite conclusions on the same file, and neither of them is wrong.
Underwriting, with a longer document list
Expect more of everything: statements, explanations, verification of the source of large deposits, and a full picture of assets held elsewhere.
Appraisal and closing
Allow time for the appraisal, and for a second one if the investor requires it. Then read the Closing Disclosure against the Loan Estimate line by line.
Jumbo against a conforming loan
| Feature | Jumbo | Conforming |
|---|---|---|
| Loan size | Above the county conforming limit | At or below it |
| Who ends up holding it | The lender, or a private investor | Usually Fannie Mae or Freddie Mac |
| Where the guidelines come from | The investor's own credit policy, not published | A published selling guide anyone can read |
| Down payment and reserves | Set by the investor; typically a larger down payment and months of post-closing reserves | As little as 3% to 5%, with reserves only where the guide requires them |
| Mortgage insurance | Usually avoided with a larger down payment; where PMI is used the HPA still governs cancellation | PMI above 80% LTV, cancellable under the HPA |
| Ability-to-repay rules | Apply | Apply |
| If one lender says no | Another may say yes on the same file — the policies genuinely differ | The guide is the same everywhere, so the answer usually is too |

Questions this raises
What is the jumbo threshold?
It depends entirely on where you are buying. FHFA publishes a conforming loan limit each year, with a baseline figure, higher limits in designated high-cost counties, and separate limits for two-, three- and four-unit properties. Because it is revised annually and varies county by county, this site deliberately does not print a dollar figure that would be wrong within a year or wrong in the next county. Look up the current limit for your county before assuming a loan is jumbo.
Why is a jumbo loan harder to get?
Because nobody is standing behind it. A conforming loan is written to a guideline Fannie Mae or Freddie Mac has agreed to buy against; a jumbo loan is risk the lender or a private investor keeps. Larger down payments, post-closing reserves, lower debt ratios and heavier documentation are all ways of managing risk that cannot be passed on. It is not about the size of the number so much as about who is left holding it.
Are jumbo rates higher than conforming rates?
This site publishes no rates, and the honest general answer is that it varies with market conditions rather than being a fixed relationship. Jumbo pricing has at times sat below conforming pricing for strong borrowers and at times well above it, because it depends on private investor appetite rather than on agency guarantee fees. Get quotes on both structures for your actual loan amount.
Is a conforming first mortgage plus a second lien cheaper?
Sometimes, and it is worth pricing. The combination keeps the first mortgage inside agency guidelines, which can help both pricing and approval, but the second lien is usually at a higher rate, may be adjustable, and carries its own costs. Price the blended payment over the years you expect to hold the loan, not the headline rate on the first mortgage.
