When buying a $1 million or higher-priced home in Austin, the type of mortgage you need depends on how much you borrow. In 2026, a mortgage above $832,750 is considered a jumbo loan in Travis, Williamson, and Hays counties. For example, if you buy a $1 million home with a 20% down payment, your $800,000 mortgage stays within the conforming loan limit.
Once your loan exceeds $832,750, different lending requirements may apply. Jumbo loans are offered under individual lender or investor guidelines, which can affect interest rates, credit requirements, down payments, cash reserves, and appraisals. Understanding these differences can help you compare financing options and plan your home purchase with greater confidence.
What changes when your mortgage becomes a jumbo loan?
Loan amount determines the category: A $1 million home with a 20% down payment has an $800,000 mortgage, which stays within the conforming loan limit but a smaller down payment could bring the loan above $832,750, making it a jumbo loan.
Interest rates can vary: Jumbo loan rates can be higher or lower than conforming loan rates. National surveys have shown lower average jumbo rates during certain periods, including October 2026.
Lending requirements depend on the lender: Each lender or investor sets its own requirements for credit scores, down payments, cash reserves, and appraisals. These requirements can vary based on the loan amount and financing program.
Where does the jumbo line actually fall in Travis, Williamson and Hays counties?
The line falls at $832,750 in all three counties for 2026, and it is a loan amount rather than a purchase price.
The Federal Housing Finance Agency sets the conforming loan limits that govern which mortgages Fannie Mae and Freddie Mac may acquire. For 2026 the baseline one-unit limit increased 3.26 percent, tracking the same 3.26 percent rise in FHFA's seasonally adjusted house-price index between the third quarters of 2024 and 2025. Under the Housing and Economic Recovery Act framework, a county designated high-cost can receive a higher ceiling, and none of the three core Austin-metro counties has that designation.
Those figures come from FHFA's 2026 county file, checked October 9, 2026. The limit applies to the original loan amount, and not to the property price or to the balance at some later point when the loan is sold.
The arithmetic separates the two ideas cleanly:
On a $1.05 million purchase, a first mortgage of $832,750 would require $217,250 down, which is where the agency-eligibility line falls. That is arithmetic describing a threshold, not a structure anyone is suggesting; whether any particular down payment suits a transaction is a question for a licensed lender.
What changes the moment the loan amount crosses $832,750?
Crossing the limit changes several things at once, which is why the file feels unfamiliar to a borrower who has only ever been conforming. All of the following may shift together once the balance exceeds $832,750:
Which rate benchmark is relevant at all, and how the note rate relates to discount points.
Maximum loan-to-value, the equity required, and how leverage above 80 percent is treated.
Explicit minimum credit score and maximum debt-to-income limits.
Months of post-closing reserves, and which assets may count toward them.
Whether a human underwriter must review the file, and how self-employment income, stock compensation and asset depletion are documented.
Whether one appraisal or two are required.
Availability of adjustable-rate, interest-only, portfolio and alternative-income structures.
None of those items has one jumbo answer. The controlling document is the dated guideline of the investor expected to own the loan, which is why two institutions can reach different conclusions on the same borrower.
Why the weekly rate in the headlines is not a quote on this loan
The most widely quoted weekly mortgage figure comes from Freddie Mac's Primary Mortgage Market Survey. As of October 8, 2026, Freddie Mac's weekly survey reported a 7.40 percent average for the 30-year fixed-rate mortgage. That average describes one narrowly specified product: conventional conforming financing, for a home purchase rather than every mortgage purpose, fully amortizing, with a 20 percent down payment and excellent borrower credit, drawn from national loan applications lenders submit through Freddie Mac's systems.
The first of those conditions excludes a jumbo loan outright. The survey does not measure jumbo financing, interest-only structures, lower down payments, second homes, investment property or cash-out refinances, and it does not report Austin closings. It is a consistent national benchmark for tracking direction, which is a different job from quoting a price.
A personalized quote reflects the loan amount, credit profile, loan-to-value, occupancy, property type, documentation method, verified reserves, the length of the rate lock, points paid, and the lender's own capacity at that moment. None of those adjustments can be recovered from a published average, and only a licensed lender or mortgage professional can produce an actual figure for a specific file.
What has the jumbo-to-conforming spread actually done?
It has gone negative. In the week ended October 2, 2026, the only survey that publishes both averages put jumbo below conforming, 7.39% against 7.49%.
Two national series produced different conforming figures within days of each other in October 2026, because they survey different populations by different means. They are not reconcilable into one true rate, and presenting either as Austin's rate would be wrong on both counts.
The Mortgage Bankers Association is the only one of the two that publishes a jumbo series, so the spread below is calculated entirely within MBA's weekly applications survey rather than by subtracting one survey's figure from another's. A negative result means the jumbo average was the lower of the two.
The spread has inverted repeatedly. MBA reported that jumbo averages were generally below conforming averages from after December 2021 until June 2023, with contemporary MBA commentary putting the inversion as wide as roughly 64 basis points in November 2022. In the opposite direction, Federal Reserve Bank of New York research documented a pre-financial-crisis jumbo premium near 25 basis points that widened to 150 basis points or more during the crisis. The reason is structural: conforming loans have a liquid agency securitization channel, while jumbo loans cannot be sold to Fannie Mae or Freddie Mac and are more often retained on a balance sheet or privately funded.
A jumbo rate is therefore not automatically the higher one, and no average establishes what an individual borrower would be offered.
How does qualification change above the conforming limit?
Crossing the limit does not produce one nationwide jumbo guideline. It changes which rules the file is judged against, from a standardized agency framework to the matrix of whichever private investor or portfolio lender is expected to hold the loan.
The practical change is less uniform qualification rather than simply harder qualification. Manual review matters most where income does not resemble salary. Self-employment analysis can extend through personal and business returns, K-1 distributions, ownership percentage, business liquidity and whether reported income is actually accessible. Restricted-stock income generally needs evidence that units vested and were distributed without restrictions, plus a supportable history and a stated calculation method, so equity granted through a corporate relocation package is documented differently from salary. Interest and dividend income ordinarily requires two years of returns or 24 months of statements.
How do leverage, reserves and credit floors step up with loan size?
Published prime-jumbo matrices step leverage down as exposure increases. The combinations below come from one lender’s published jumbo guidelines and illustrate the shape rather than a standard.
A separate January 2025 matrix allowed 80 percent to $1.5 million, 75 percent to $2 million and 70 percent to $2.5 million, placing its tier boundaries a full step below the table above. Both are published, and neither binds the other's investor.
Reserves follow the same pattern. A month of PITIA means one month of the property's principal, interest, real-estate taxes, applicable insurance and association dues or assessments, the same line items that drive annual carrying cost. Reserves are the verified assets remaining after the down payment, closing costs and prepaid items are removed.
At a $2 million loan those same guidelines require 12, 12 and 9 months respectively, so the guideline chosen matters less at that size than the structure does: Guideline C rises to 24 months above 80 percent loan-to-value, and to 18 months on an interest-only balance. Additional financed properties commonly add two, three or six months each, and gift funds, unsecured borrowing or an undrawn credit line may be excluded from usable reserves entirely. One published guideline discounts retirement accounts invested in stocks, bonds or mutual funds by 30 percent for market volatility. Twelve months of reserves does not mean twelve payments in a checking account, and net worth does not count at face value either. Neither these guidelines nor the leverage matrix above states an effective date on its face, and an investor guideline governs only as of its own date. The document to ask a lender for is the dated guideline for the investor expected to buy that loan.
Which costs scale with the loan amount?
Several upfront charges increase mechanically with the balance.
Discount points. One point equals 1 percent of the loan amount. That is $8,327.50 on a loan at the $832,750 limit and $10,000 on a $1 million loan. Paying points buys a lower note rate at closing, but one point has no standardized rate reduction across lenders or across dates, per CFPB guidance.
Percentage-based origination charges. A fee expressed as a percentage of the balance scales the same way, while underwriting, processing, appraisal and settlement charges are often flat-dollar.
Leverage above 80 percent. Conventional borrowers putting down less than 20 percent typically pay mortgage insurance priced by down payment and credit. On a jumbo there is no equivalent schedule: published guidelines variously require approved insurance, restrict the maximum loan-to-value, or absorb the risk through pricing.
A second appraisal adds collateral expense wherever the investor's loan-size trigger reaches it, and that trigger is where published guidelines disagree most visibly. No federal rule sets one.
Where two reports are required, published policies commonly use the lower supported value for the loan-to-value calculation rather than averaging them. Some programs instead order one appraisal plus a collateral desk analysis or field review below their threshold. A separate federal rule requires a second appraisal on certain higher-priced mortgage loans where the seller bought the home within the past 180 days and the price has risen more than 10 percent (within 90 days) or 20 percent (91 to 180 days). It is an anti-flipping provision, not a jumbo threshold.
When comparing mortgage offers, it's important to look beyond the interest rate. For a fair comparison, make sure the offers have the same rate-lock date, loan amount, loan-to-value ratio, property use, loan term, and repayment structure. Also compare discount points, origination fees, and lender credits to understand the overall cost of each loan.
What the rules say about financing after an all-cash purchase
Buying a home with cash does not mean you have to keep all your money tied up in the property. Buyers can also choose to take out a mortgage after completing the purchase. Under Fannie Mae's delayed-financing exception, buyers who purchased a home with cash within the past six months may qualify for a cash-out refinance without having to wait the usual six months.
According to Fannie Mae's Selling Guide, buyers must meet certain conditions to qualify:
Original purchase: The home must have been purchased through a transaction between independent parties.
Proof of cash purchase: The settlement statement must confirm that no mortgage was used to buy the property.
Property ownership: A title search must show that the property has no existing liens.
Source of funds: Buyers must provide documents showing where the purchase money came from, and any gifted funds cannot be reimbursed.
Loan amount: The new mortgage cannot exceed the documented original investment plus eligible closing costs and discount points. The loan is priced as a cash-out refinance.
These requirements help determine whether a buyer can access some of the money invested in the home through a mortgage after completing an all-cash purchase.
Without that exception, the general agency cash-out rule requires at least one borrower to have held title for six months. A portfolio jumbo investor is not bound by the agency rule at all and may apply different seasoning periods, loan-to-value limits or definitions of invested cash, so the exception should not be assumed to control a jumbo refinance. Texas adds a further layer: a refinance secured by homestead property can raise state constitutional home-equity questions the federal rule does not resolve. Those are questions for a Texas real estate attorney and a lender respectively, and better settled before the cash offer is written. Where the purchase is being managed from out of state, both have to be engaged ahead of that offer.
Settling the loan amount before the offer is written
The number that decides which of these two regimes applies is the loan amount. On a $1.05 million purchase at 20 percent down, the difference between the two regimes is $7,250 of loan balance, and two buyers with identical finances and different cash contributions can have their files judged by different rules on leverage, reserves, documentation and valuation. Settling the intended loan amount before the offer is written tells the buyer which set of rules applies before the contract deadlines start.

Frequently Asked Questions
Do rising Austin home prices raise the conforming loan limit locally?
No. The Federal Housing Finance Agency (FHFA) sets the conforming loan limit based on national home price trends rather than local prices. Counties classified as high-cost areas may have higher limits, but Travis, Williamson, and Hays counties do not fall into that category in 2026. Their conforming loan limit remains $832,750, regardless of changes in local home prices.
Is "super-jumbo" an official loan category?
No. Super-jumbo is a term lenders and investors use for larger jumbo loans, rather than an official federal loan category. The amount that qualifies as super-jumbo varies by lender, with some applying additional requirements at $1.5 million, $2 million, $2.5 million, or $3 million. The specific requirements depend on the lender's current guidelines.
Does an automated agency approval count for anything on a jumbo file?
An automated approval from Fannie Mae or Freddie Mac does not automatically qualify you for a jumbo loan. Some jumbo lenders consider automated results as part of their review, while others require a detailed manual assessment of your income, assets, credit, and financial documents. Final approval depends on the lender's requirements.
Does asset depletion work the same way at every lender?
No. Lenders use different methods to calculate qualifying income from your savings, investments, and other eligible assets. Some divide eligible assets over a set number of months, while others use a repayment-based calculation. The assets accepted and the amount counted can also vary, including how retirement accounts are treated based on your age.
Is an interest-only jumbo loan a Qualified Mortgage?
Generally, no. Interest-only jumbo loans typically fall outside the federal Qualified Mortgage (QM) rules because they allow borrowers to pay only interest for an initial period. However, lenders must still assess your ability to repay the loan, generally using principal-and-interest payments. During the interest-only period, your payments do not reduce the original loan balance.
