In short
A jumbo loan is a mortgage that exceeds the conforming loan limits backed by Fannie Mae and Freddie Mac. It's underwritten by banks and private investors under their own guidelines, typically requiring deeper documentation, more reserves, and stronger credit — with standards that vary significantly between lenders.

What is a jumbo loan and how is it different from a conventional loan?
A jumbo loan is a mortgage that exceeds the conforming loan limits set for Fannie Mae and Freddie Mac. Because the government-sponsored enterprises can't back it, the loan is held by banks and private investors who write their own guidelines — which typically means deeper documentation, stronger reserve requirements, and closer scrutiny of income and credit. Guidelines vary meaningfully from one jumbo investor to the next, so file structure and lender selection drive the outcome. As a broker, I shop jumbo files across multiple investors and match your specific income and asset profile to the lender that treats it best.
Key takeaways
A jumbo loan is any mortgage above the conforming loan limits — too large for Fannie Mae and Freddie Mac, so it's underwritten by banks and investors under their own rules. In Lakeway, Boerne, The Woodlands, and a growing share of the Austin area, that's not exotic territory; it's where ordinary move-up purchases land. Jumbo guidelines vary widely between lenders, which means the same file can be declined at one and approved at another. I've structured complex, high-value files since 2003 — over $400 million funded — and on a jumbo, that experience is the product.
When a Loan Becomes a Jumbo
Every year, the federal government sets conforming loan limits — the maximum loan size Fannie Mae and Freddie Mac will back. Borrow above that line and you're in jumbo territory: the loan is too large for the conventional machine, so it's underwritten and held by banks and investors under their own guidelines.
That one change ripples through everything. Jumbo lenders scrutinize files more closely, documentation runs deeper, and guidelines vary dramatically from one investor to the next. The same borrower can be declined at one jumbo shop and approved at another — not because anything about the file changed, but because the guidelines did. That variability is exactly why who structures your loan matters more on a jumbo than on almost any other product.
Where Jumbo Loans Come Into Play Around Here
You don't need a mansion to need a jumbo loan anymore. In the markets I serve, jumbo financing is everyday reality:
- Lakeway — lakefront and hill-view properties on Lake Travis routinely price past conforming limits.
- Boerne and the Hill Country — acreage, custom builds, and view lots push values up fast.
- The Woodlands — established executive neighborhoods where move-up buyers land after a decade of equity growth.
- Austin and Dripping Springs — where ordinary family homes in the right school zones can brush against the limits.
For many of my clients, the jumbo question arrives with the move-up purchase: the second or third home, bought with real equity from the last one and a more complex financial life than they had at 28.
What Jumbo Underwriting Actually Looks At
Jumbo guidelines are lender-specific, but the themes are consistent:
- Reserves. Jumbo lenders typically want to see months of payments in liquid assets after closing — the exact number varies by lender and loan size.
- Documentation depth. Expect a fuller picture: complete tax returns, asset sourcing, and explanations for anything unusual.
- Credit depth. Generally stronger credit expectations than conforming loans, though standards differ by investor.
- Property scrutiny. Higher-value homes often mean more rigorous appraisal review, sometimes two appraisals on larger loans.
- Income complexity. This is where jumbo files get interesting — and where most of them go sideways. Executive compensation with RSUs and bonuses, self-employment income across multiple entities, investment income: standard-issue for jumbo borrowers, and easy to underwrite badly.
Why the Right Strategist Matters at This Level
I've been structuring loans since 2003 — through Wells Fargo at national volume, through banks, independent brokers, and correspondent lenders, across every rate cycle. More than $400 million funded. What that history buys you on a jumbo file is pattern recognition: I've seen how different investors treat bonus income, RSU vesting schedules, K-1 distributions, and asset-based qualifying, and I know where a given file will be welcomed rather than merely tolerated.
Because I broker rather than work one bank's menu, your file gets shopped across multiple jumbo investors — and on loans this size, small differences in guidelines and pricing translate into real money. A big bank gives you a rate. I give you a strategy, built around your full financial picture — and I'm the same person with you from your first question to your closing table.
A Word on Payment Math
At jumbo size, the sticker price dominates every conversation, and it's the wrong place to stare. It's not the cost of the home, it's the cost of the home on a monthly basis. Structure — the down payment size, how your income is presented, how reserves are positioned, whether a first-and-second combination beats a single jumbo loan — can move the monthly number meaningfully. Those are strategy decisions, and we make them deliberately before you're under contract, not in week three of escrow.
How I Run a Jumbo File
- Full financial review — income structure, assets, reserves, and goals before we talk price range.
- Structure decisions — loan size versus down payment, single loan versus combination, documentation approach.
- Investor matching — the file goes where its specific profile is a fit, at the sharpest available terms.
- A clean escrow — jumbo underwriting is document-heavy; I front-load the work so closing day is boring. Boring is the goal.
Strategy always wins — and it wins bigger at jumbo scale.

Is this loan right for you?
Who it's for

Who it may not fit
- Buyers whose loan amount fits within conforming limits, where conventional financing usually makes more sense
- Borrowers without the reserves jumbo investors typically require — we may structure around it, but it needs a plan

Frequently asked questions
How do I know if I need a jumbo loan?
If your loan amount — purchase price minus down payment — exceeds the conforming loan limit for your county, you're in jumbo territory. The limits adjust periodically, so I'll confirm where the line sits for your target area. Sometimes a modestly larger down payment or a first-and-second loan combination keeps you under the limit, and sometimes crossing it is the better deal. We run both scenarios before you commit to either.
Are jumbo loans harder to qualify for?
They're more thorough, not impossible. Expect deeper documentation, stronger reserve requirements — typically several months of payments in liquid assets after closing — and generally higher credit expectations than a conforming loan. The bigger truth is that standards vary widely between jumbo investors, so the right lender match matters as much as your raw numbers. That match is my job.
My income is complicated — bonuses, RSUs, self-employment. Is that a problem for a jumbo loan?
It's normal for a jumbo loan — most jumbo borrowers have complex income. The risk isn't the complexity; it's a loan officer who documents it badly or sends it to an investor whose guidelines penalize it. I've structured files with executive compensation, multi-entity self-employment, and investment income since 2003, and I place each file with the investor whose guidelines read that income most favorably.
Do jumbo loans have higher rates than conventional loans?
Not necessarily — jumbo pricing moves independently of conforming pricing and depends on the investor, your profile, and the loan structure. Sometimes jumbo pricing is very competitive with conforming; sometimes it isn't. Rather than assume either way, I price your specific scenario across multiple investors, and we also compare structures — like a conforming first loan plus a second — to see which total monthly picture wins.
How much do I need to put down on a jumbo loan?
It varies by investor, loan size, and your overall profile — there's no single answer, and larger loans generally want more equity. Down payment size also interacts with pricing and reserve requirements, so the 'right' down payment is a strategy decision, not a fixed rule. We'll model a few structures side by side and pick the one that best serves your monthly payment and your liquidity.
