Jumbo Loans in Michigan

Where conventional ends and jumbo begins: $832,750

Everything about a jumbo loan starts with one number. For 2026, the baseline conforming loan limit for a one-unit property is $832,750. A loan at or below that figure is "conforming" — it fits inside the rulebook Fannie Mae and Freddie Mac publish, which is why conventional financing is essentially a commodity. A loan even a dollar above it is a jumbo loan, also called a high-balance mortgage, and it lives outside that rulebook entirely.

That distinction is not cosmetic. Conforming loans can be sold to Fannie and Freddie, so the government-sponsored enterprises effectively backstop them and the rules barely differ from lender to lender. Nobody buys a jumbo loan off the shelf that way. Each lender holds its jumbo loans on its own books or sells them to private investors, which means each lender writes its own guidelines, sets its own credit floors, and decides for itself how much risk it wants to carry. That's why the same borrower can hear "no" from one bank and "absolutely" from another on a loan of the identical size.

One more wrinkle worth knowing: in a handful of the country's most expensive counties, the conforming limit is set higher than the baseline, creating a band sometimes called "high-balance conforming." Michigan's counties all sit at the baseline, so for a Michigan home the line is clean — above $832,750 on a one-unit property, you're shopping for a jumbo loan.

Who needs a jumbo loan in Michigan

You need a jumbo loan when the amount you're financing crosses the conforming line — which, in practice, happens in specific corners of the Michigan market. The files I see most often:

• Buyers in Oakland County's higher-end communities — Birmingham, Bloomfield Hills, the lakes — where seven-figure list prices are routine
• Move-up buyers trading a starter home for a larger one in a top school district, financing well past the limit even with strong equity
• Luxury and waterfront purchases — lakefront property on Michigan's inland lakes or the Great Lakes shoreline
• Buyers making a sizable down payment on an expensive home, where even 20% or 30% down still leaves a loan above $832,750
• Owners of high-cost homes refinancing — a rate-and-term or cash-out refinance on a property whose balance sits in jumbo territory
• Self-employed buyers in those markets, who often carry the down payment but get tripped up by jumbo income documentation — a problem I solve every week

If the home you want pushes your loan past the limit, that's not a problem — it's just a different category of financing, and one Atlantis arranges constantly.

What jumbo lenders ask for — and why it's more

Because no agency stands behind a jumbo loan, the lender carries the full risk — so the qualifying bar generally sits higher than on a conventional loan. Treat these as honest ranges, not promises; every lender publishes its own guidelines, and matching your file to the right one is the whole job.

• Down payment: expect to put more down than on a conforming loan — commonly 10–20% or more, with the larger loan amounts and lower credit scores landing at the higher end. Some programs go lower for the strongest profiles; others want more.
• Credit score: jumbo programs generally want stronger credit than conventional, with the most favorable terms reserved for higher scores. Where one lender's floor stops, another's may begin.
• Cash reserves: this is the big one. Jumbo lenders typically want to see several months — sometimes six, twelve, or more — of housing payments sitting in the bank after closing, scaling with the loan size. It's their proof you can weather a rough stretch.
• Income documentation: jumbo underwriting scrutinizes income harder than any conventional file. For W-2 earners that's straightforward; for self-employed borrowers it's the usual sticking point.
• The property: jumbo appraisals are thorough, and some lenders require a second appraisal on the largest loans.

You'll notice I haven't quoted a rate or a payment anywhere on this page. That's deliberate. Jumbo pricing depends on your credit, your down payment, the property, your reserves, and the program — any number I printed here would be wrong for your file. The honest version is a conversation.

The self-employed jumbo problem — and how to solve it

Here's a pattern I see constantly in the higher-end Michigan markets: a business owner has the down payment, the credit, and the reserves for a luxury home — but a traditional jumbo lender chokes on the income documentation, because the tax returns a good accountant prepares are designed to minimize taxable income, not impress an underwriter.

There are real answers for this. A self-employed buyer can sometimes qualify for a jumbo through a bank statement loan, which documents income on 12 or 24 months of deposits instead of tax returns. Borrowers with substantial savings or investment accounts may fit an asset depletion loan, which converts a liquid portfolio into qualifying income — a natural fit for the high-net-worth buyer whose money is in assets rather than a paycheck. Both of these can be written at jumbo loan sizes.

Knowing which lenders pair these alternative-documentation programs with jumbo limits — and which ones decline the combination outright — is exactly the kind of detail a single bank's loan officer can't help you with. A broker can.

Why a broker beats one bank on a jumbo loan

This is the part of the jumbo market almost nobody explains. When you walk into a bank for a jumbo loan, you get that bank's single jumbo program — one set of guidelines, one credit floor, one reserve requirement, one income policy. If your file is a 715 and their program wants a 720, the answer is no, and their loan officer isn't going to tell you that the lender down the street would have said yes. They can't. They work for one menu.

Atlantis Mortgage is a wholesale mortgage brokerage. I take the same file — your credit, your down payment, your reserves, the property — and shop it across more than 50 wholesale lenders, each with its own jumbo guidelines, reserve requirements, and pricing. They compete for your loan; I place it where it fits best.

And this matters more on jumbo loans than on almost anything else, precisely because there's no central rulebook. Conventional loans barely differ from lender to lender because Fannie and Freddie set the rules. Jumbo loans differ enormously — one lender wants twelve months of reserves where another wants six, one caps the down payment requirement where another flexes it for a strong file, one declines self-employed income that another welcomes. The spread between the best and worst home for the same jumbo file is real money, and sometimes the difference between approved and declined.

After 28 years and more than $2 billion in funded loans, I can usually tell you within a phone call which lenders want your jumbo file — and which ones would have wasted three weeks of your life. And at every step you're talking to me, Jason Yourofsky (NMLS #137016), not a rotating cast of processors. If a bank already turned you down on a jumbo, that's often where I start — see how a conventional loan compares once you're near the limit, or just call and we'll find the line together.

Jumbo loan FAQ

Straight answers to the questions Michigan buyers actually ask me.

What is a jumbo loan?

A jumbo loan is any mortgage larger than the conforming loan limit, which for 2026 is $832,750 on a one-unit home. Because a jumbo loan exceeds that limit, it can't be sold to Fannie Mae or Freddie Mac, so lenders set their own guidelines, credit floors, and reserve requirements. It is also called a high-balance mortgage.

What is the jumbo loan limit in Michigan for 2026?

In Michigan, any loan above $832,750 on a one-unit property is a jumbo loan for 2026. Michigan's counties all sit at the baseline conforming limit rather than a high-cost exception, so that single figure is the line statewide. A loan at or below it is conventional; a loan above it is jumbo.

How much down payment does a jumbo loan require?

Jumbo loans generally require a larger down payment than conventional loans — commonly 10–20% or more, with larger loan amounts and lower credit scores landing at the higher end. Some programs allow less for the strongest borrower profiles, while others require more. Because Atlantis Mortgage shops 50+ lenders, the requirement depends on which program fits your file.

Are jumbo loans harder to qualify for?

Jumbo loans typically have stricter requirements than conventional loans because no government agency backs them and the lender carries the full risk. Expect a stronger credit profile, more cash reserves after closing, and tighter income documentation. The exact bar varies by lender, which is why comparing multiple programs through a broker matters more on jumbo loans than on conventional ones.

Can a self-employed borrower get a jumbo loan?

Yes. Self-employed buyers often have the down payment and reserves for a jumbo loan but struggle with traditional income documentation. Atlantis Mortgage arranges jumbo financing through alternative-documentation programs — including bank statement loans that qualify on deposits and asset depletion loans that convert savings into income — at jumbo loan sizes. The right path depends on your income picture and which lenders pair these programs with high balances.

Why use a mortgage broker for a jumbo loan?

A single bank can only offer its own jumbo program, while a broker shops your file across many lenders. Because jumbo loans have no central rulebook, guidelines differ enormously between lenders — on reserves, credit floors, down payment, and income documentation. Atlantis Mortgage compares more than 50 wholesale lenders to place your jumbo loan where it fits best, which can be the difference between approved and declined on a file of the same size.
