Jumbo Loan

A jumbo loan is a mortgage larger than the limit at which Fannie Mae or Freddie Mac may buy it. It is a market word: Regulation Z uses it exactly once, in quotation marks. Its real consequence is that the loan leaves the standardized market, and one federal protection attaches to it a full percentage point later.

Quick Summary

  • The threshold is not a separate number. It is the conforming loan limit, so a jumbo loan in one county can be an ordinary conforming loan in another.
  • The size is measured as of the date the loan's interest rate is set, not at closing, so locking either side of a January limit change can decide the question.
  • A jumbo loan is still a conventional loan. Jumbo describes size; conventional describes the absence of a federal guarantee.
  • Because no enterprise will buy it, eligibility is the lender's own credit standards rather than a published guideline a borrower can read in advance.
  • The higher-priced mortgage loan test is 2.5 percentage points over the market benchmark for a jumbo first lien, against 1.5 for one at or under the limit, so the protections that come with that label attach later.

Definition

A jumbo loan is a mortgage whose principal balance exceeds the maximum Fannie Mae or Freddie Mac may buy, and which therefore has to be held by the lender or sold into the private market rather than to a government-sponsored enterprise. For a one-unit property in most of the country that threshold is $832,750, but it is higher in high-cost counties, higher again for multi-unit properties, and higher still in Alaska, Hawaii, Guam and the U.S. Virgin Islands, so the same loan amount can be jumbo in one place and ordinary in another.

The naming deserves a precise answer, because the usual one is vague. "Jumbo" is a market word, and the closest federal law comes to adopting it is instructive: it appears exactly once in Regulation Z, in quotation marks, in the Official Interpretations. Comment 35(a)(1)-3, headed "Threshold for 'jumbo' loans", explains that Regulation Z "provides a separate threshold for determining whether a transaction is a higher-priced mortgage loan … when the principal balance exceeds the limit in effect as of the date the transaction's rate is set for the maximum principal obligation eligible for purchase by Freddie Mac (a 'jumbo' loan)." So the regulator uses the word as shorthand while declining to define it, and the actual legal test is stated by reference to the Freddie Mac limit rather than to any independent standard.

Advanced Explanation

The one federal consequence, and it runs against the borrower. A first-lien loan on a principal dwelling is a higher-priced mortgage loan when its annual percentage rate exceeds the average prime offer rate for a comparable transaction by 1.5 percentage points or more, where the principal obligation does not exceed the Freddie Mac limit, and by 2.5 percentage points or more where it does (12 CFR 1026.35(a)(1)(i) and (ii)). A subordinate lien uses 3.5 regardless of size (subparagraph (iii)), so the jumbo threshold reaches first liens only.

That one-point gap is not cosmetic, because higher-priced status is what triggers two protections. A creditor may not extend a higher-priced mortgage loan secured by a first lien on a principal dwelling unless an escrow account for taxes and insurance is established before consummation (12 CFR 1026.35(b)(1)). And a covered transaction may not carry a prepayment penalty unless it is not a higher-priced mortgage loan, among other conditions (12 CFR 1026.43(g)(1)(ii)(C)). A jumbo borrower therefore has to be priced a full percentage point further above the market before either protection attaches. The reasoning behind the distinction is that large loans price differently from small ones, so the same spread over the benchmark carries a different meaning; the effect on an individual borrower is the same either way.

When the size is measured, and why the date matters. Both the higher-priced test and the limit comparison are made "as of the date the transaction's interest rate is set", and where the rate is set more than once the Official Interpretations direct the creditor to "use the last date the interest rate is set before consummation" (comment 35(a)(1)-2). Since FHFA publishes new limits each November effective January 1, a loan near the line that locks in December is tested against a different limit from one that locks in January, even if both close in the same month.

What leaving the standardized market actually changes. With no enterprise bid, the loan is held on the lender's balance sheet or sold into a private securitization. The consequences are structural rather than legal. Eligibility is set by the individual lender's credit policy rather than by a published selling guide, so two lenders can reach genuinely different answers on the same file and neither has a public standard a borrower can check in advance. Underwriting tends to be more document-intensive for the same reason: the lender is deciding whether it wants the risk itself rather than whether the loan fits someone else's rules. And because the lender may be keeping the loan, terms are more open to negotiation than on a loan that has to conform to a purchaser's template.

What does not change. The federal consumer protections that turn on the dwelling rather than on who buys the loan apply in full. The ability-to-repay requirement reaches almost every closed-end consumer mortgage secured by a dwelling, and nothing in it turns on loan size. The Loan Estimate and Closing Disclosure, their deadlines and their tolerance rules apply the same way. So does the escrow account regime under Regulation X, once an account exists. A jumbo loan is a mortgage with a smaller resale market, not a loan outside the consumer protection system.

How to Remember

Jumbo is not a program and not a credit grade. It is the word for a loan that outgrew its buyer, and the threshold is your county's conforming limit on the day you lock.

Used in a Sentence

“Because the purchase price left her borrowing more than her county's limit, the mortgage was a jumbo loan and the lender kept it on its own books.”

How It Works

The lender compares the loan's principal obligation to the conforming limit for the county and unit count, using the limit in effect on the date the rate is set. Under it, the loan can be delivered to an enterprise and is priced and underwritten against that enterprise's published standards. Over it, the lender underwrites to its own policy and either portfolios the loan or places it with a private buyer. Everything else about the transaction, the disclosures, the appraisal, the ability-to-repay determination, proceeds identically.

A hypothetical example of the threshold that actually differs, since it is the one thing about a jumbo loan federal law says outright. Suppose the average prime offer rate for a comparable thirty-year fixed first lien is 6.00%. Two borrowers each take a first-lien loan on a principal dwelling, and each loan carries an annual percentage rate of 8.20%, which is 8.20 − 6.00 = 2.20 percentage points above the benchmark.

Loan A has a principal obligation at or under the Freddie Mac limit on the day its rate was set. Its test is 1.5 points, and 2.20 is above it, so Loan A is a higher-priced mortgage loan. An escrow account must be established before consummation, and no prepayment penalty may be charged.

Loan B is over that limit on the same day. Its test is 2.5 points, and 2.20 is below it, so Loan B is not a higher-priced mortgage loan. Neither protection attaches, and a prepayment penalty becomes possible if the loan's other conditions are met.

Same spread over the market, same day, same product, opposite answers, decided only by which side of the limit the loan amount fell on. Figures are illustrative.

Pros and Cons

Pros

  • It makes purchases possible above the conforming limit, which in expensive markets is most of the market.
  • Because the lender may keep the loan, structure and terms can be negotiated rather than fitted to a purchaser's template.
  • The federal disclosure, ability-to-repay and escrow rules apply in the same way as on any other mortgage secured by a dwelling.
  • Nothing about the label reflects on the borrower. It describes the loan's size relative to a statutory purchase limit.

Cons

  • Eligibility is the lender's own credit policy, so there is no published standard to check yourself against before applying, and answers differ between lenders on identical facts.
  • The higher-priced mortgage loan test is a full percentage point more permissive, so the escrow requirement and the prepayment-penalty bar attach later than they would on a smaller loan.
  • The threshold moves annually and is county-specific, so a loan can become jumbo through a change in the calendar or the address rather than the amount.
  • Underwriting is generally more document-intensive, because the lender is deciding whether to carry the risk itself.
  • Pricing depends on private appetite for the loan rather than on a liquid agency market, which makes it more variable between lenders and over time.

People Also Asked

Answers to the most frequently asked questions.

What makes a loan a jumbo loan?
Its size relative to the conforming loan limit for the county and the number of units, measured as of the date the interest rate is set. For a one-unit property in most of the country that limit is $832,750, but it is higher in high-cost counties, for multi-unit properties, and in Alaska, Hawaii, Guam and the U.S. Virgin Islands. The word itself carries no legal definition: Regulation Z uses it exactly once, in quotation marks, in its Official Interpretations, and the operative test is stated by reference to the Freddie Mac limit instead.
Is a jumbo loan a conventional loan?
Yes. Conventional means the loan carries no federal guaranty or insurance, and a jumbo loan carries none. Conforming means the loan is eligible for purchase by Fannie Mae or Freddie Mac, and a jumbo loan is not. So a jumbo loan is conventional and non-conforming. The two labels are answering different questions, which is why a loan can be conventional without being conforming but not the other way round.
Do jumbo loans have higher interest rates?
Not as a rule. Pricing on a jumbo loan reflects the appetite of whoever will hold it, so it moves relative to conforming pricing over time and differs more between lenders than agency pricing does. What is fixed rather than variable is the regulatory difference: a jumbo first lien has to be 2.5 percentage points above the market benchmark before it counts as higher-priced, against 1.5 for a loan at or under the limit.
Are jumbo borrowers protected by the same mortgage rules?
Mostly yes. The ability-to-repay requirement covers almost every closed-end consumer mortgage secured by a dwelling, whoever ends up buying the loan, and the Loan Estimate and Closing Disclosure rules apply identically. The exception is the higher-priced mortgage loan threshold, which is a full percentage point more permissive for a loan above the Freddie Mac limit, so the mandatory escrow account and the bar on prepayment penalties attach later than they would on a smaller loan.
Can a loan stop being jumbo without the amount changing?
Yes, in two ways. The conforming loan limit is reset each January, so a loan whose rate is set after the change is tested against the new figure. And the limit is county-specific, so the same amount can be jumbo in one county and conforming in the next one over. The measurement date is the date the interest rate is set, and where it is set more than once, the last such date before consummation.
