Conventional Loan or Jumbo Loan: Which Do You Need to Buy a Home in Maricopa County, AZ?

A conventional loan is a mortgage that isn't backed by a government agency (like the VA or FHA) but does follow underwriting guidelines set by Fannie Mae and Freddie Mac. Because these two agencies buy and guarantee conventional loans, there's a cap on how large the loan can be. For 2026, that baseline conforming loan limit is $832,750 for a single-family home in Arizona, including all of Maricopa County.

Arizona doesn't have any FHFA-designated high-cost areas, so this baseline number applies whether you're buying in Scottsdale, Buckeye, or Fountain Hills. A jumbo loan is simply a mortgage that exceeds that conforming limit. Because Fannie Mae and Freddie Mac won't buy or guarantee a jumbo loan, the lender is taking on more risk by holding it, and that changes the terms.

Jumbo loans typically come with stricter credit score requirements, larger down payments, more cash reserve requirements, and sometimes a slightly different interest rate structure than conventional loans. Why This Matters More in Maricopa County Right Now A lot of buyers assume the jumbo line is reserved for ultra-luxury purchases. In Maricopa County, that's not really true anymore.

With home prices in areas like Paradise Valley, Arcadia, North Scottsdale, and parts of Gilbert and Chandler regularly landing in the $700K, $1.2M range, plenty of otherwise "normal" move-up buyers end up needing a jumbo loan simply because of where they're buying, not because the home is unusually extravagant.

This is the part that trips people up: it's not the purchase price of the home that determines whether you need a jumbo loan, it's the amount you're financing. If you're buying a $950,000 home in Cave Creek but putting down $200,000, your loan amount is $750,000, which is under the conforming limit. You'd likely qualify for a conventional loan.

But if you're buying a $900,000 home with 10% down, your loan amount is $810,000, still conventional, but getting close to the line. Put 5% down on that same home, and your loan jumps to $855,000, pushing you into jumbo territory. This is exactly why your down payment strategy and your loan type are connected decisions, not two separate ones.

1. Get Clear on Your Target Price Range Before you fall in love with a specific home, know roughly where you're shopping. If you're consistently looking at homes from $750K up, it's worth having the jumbo conversation with a lender early, not after you've written an offer. 2. Talk Down Payment Percentage, Not Just Dollar Amount Ask your lender to run scenarios at a few different down payment levels (10%, 15%, 20%) so you can see exactly where your loan amount crosses into jumbo territory for the specific price point you're considering.

3. Get Pre-Approved for Both, If You're Near the Line If your loan amount is going to land close to $832,750 either way, ask your lender whether it makes sense to get pre-approved under both scenarios. This gives you flexibility to adjust your down payment or offer price without starting the approval process over. 4. Understand the Reserve Requirements Early Jumbo loans often require you to show several months of mortgage payments in reserve, sometimes 6 to 12 months, sitting in liquid accounts separate from your down payment and closing costs.

This catches buyers off guard more than almost anything else in the jumbo process. Know this number well before you're under contract. 5. Loop In Your Agent on Timing Jumbo loans can sometimes take a bit longer to underwrite than conventional loans because of the additional documentation involved. If you're writing an offer in a competitive situation, your agent needs to know which loan type you're using so the closing timeline in your offer is realistic.

Assuming a lower down payment always helps them win a bidding situation. A smaller down payment that pushes a buyer into jumbo financing can actually make an offer look less competitive to a seller, since jumbo loans are sometimes perceived as having a longer or less certain closing timeline. Not asking about rate differences early. Jumbo rates aren't automatically higher than conventional rates, sometimes they're comparable, sometimes not, depending on the lender and the market.

Buyers who assume one way or the other without asking can misjudge their monthly payment. Waiting until after the offer is accepted to discuss reserve requirements. This is one of the most common last-minute stress points in a jumbo transaction. It needs to be part of the pre-approval conversation, not a surprise during underwriting. Forgetting that the limit is set annually.

Conforming loan limits change every year. A number you remember from a previous home purchase, or from a friend's experience a couple years ago, may not reflect this year's limit.

Scenario 1: The Move-Up Buyer in Gilbert. A family is selling their starter home and moving into a $780,000 home in a Gilbert neighborhood with better schools. With proceeds from their sale, they're putting 20% down, bringing their loan amount to $624,000, comfortably under the conforming limit. They qualify for a conventional loan with fairly standard documentation.

Scenario 2: The Relocating Professional in Scottsdale. A buyer relocating for work finds a $1.05 million home in North Scottsdale. With 15% down, their loan amount is $892,500, above the $832,750 conforming limit, making this a jumbo loan. Because they looped their lender in early, they knew going into the offer that they'd need to show additional reserves, and they built extra time into their closing timeline to account for it.

Is a jumbo loan harder to qualify for than a conventional loan? Generally, yes. Jumbo loans typically require stronger credit, a lower debt-to-income ratio, and more cash reserves than conventional loans, since the lender is holding more risk without Fannie Mae or Freddie Mac backing. Do jumbo loans always have higher interest rates? Not necessarily.

Rate differences vary by lender and by market conditions. Some lenders price jumbo loans very competitively, especially for well-qualified borrowers. Always ask for a direct rate comparison rather than assuming. Can I avoid a jumbo loan by putting more money down? Yes, if a larger down payment brings your loan amount under $832,750, you can qualify for a conventional loan even on a higher-priced home.

This is a common strategy for buyers who are close to the line. Does the conforming loan limit change every year? Yes. The Federal Housing Finance Agency (FHFA) updates conforming loan limits annually based on national home price data. It's worth confirming the current year's number with your lender rather than relying on a figure from a past purchase.

Is the loan limit different in different parts of Maricopa County? No. Arizona does not have any FHFA-designated high-cost areas, so the same baseline conforming loan limit applies whether you're buying in downtown Phoenix, Buckeye, Queen Creek, or Paradise Valley. Should I talk to a lender before I start house hunting? Yes, especially if you expect to be shopping anywhere near the conforming loan limit.

Knowing your loan type ahead of time helps you and your agent target the right homes and write offers with realistic terms and timelines.
