A resident in Phoenix can carry $250,000 in student debt, make $70,000 a year, and be one signed contract away from earning three times that. A conventional underwriter sees the debt and the current paycheck. A physician program sees the contract and the career. That gap is why the product exists, and it is why a surprising number of doctors in the Valley buy a home before they have a full year of attending pay.

It is also a product with real tradeoffs, and a broker who only sells it is not telling you the whole story. Here is how it works and when it makes sense.

Who qualifies

Most physician programs cover MDs and DOs, including residents, fellows, and new attendings. Many extend to dentists, podiatrists, optometrists, and veterinarians, and some include advanced practice providers. It is a lender by lender list, so confirm yours before you build a plan around it.

Eligibility is usually tighter on the property than on the person. The home generally has to be a primary residence, and many programs limit the loan amount or the number of units. If you want to rent out part of the house or buy a second property, that is a separate conversation, and our loan programs page shows what else we can shop.

Credit still matters. Most lenders want a middle score in the 700s or better for the best terms, and a thin credit file is common for residents who have lived on student loans for a decade. We have to see how yours looks before anyone can promise a rate.

How the lender counts your income and debt

The two big differences from conventional underwriting are the income and the student loans. Both are where a physician program saves you.

Income. If you have not started yet, many lenders accept the signed employment contract plus proof of your license or pending license, as long as the start date is close enough, often within about 60 to 90 days of closing. You do not need a pay stub to qualify on a job you have not started. Our guide to buying a house with a new job in Arizona covers the standard rules, and the physician version is more flexible on timing.

Student loans. A conventional loan often applies a flat percentage of your balance as the monthly payment when no payment appears on your credit report. On $250,000 that can add well over a thousand dollars a month to your debt before you have bought anything. Physician programs commonly use your actual income driven payment, or set aside deferred loans, which can drop your debt to income ratio by a wide margin. The federal income driven repayment plans explain how those payments are set, and our guide to buying a house with student loan debt shows the conventional math.

For the ratios themselves, read what debt to income limits lenders allow in Arizona. The Consumer Financial Protection Bureau also publishes a plain English overview of how lenders review your finances.

The monthly math

Here is a worked example. The numbers are illustrative, not a quote, and they assume the same 7.25% rate on every option, which will not be true in real life. A doctor in Scottsdale is buying an $800,000 home.

The physician loan does not make the house cheaper. It makes the house reachable on the cash you have today.

The mortgage insurance line uses a rough 0.55% annual estimate, and real private mortgage insurance varies with your credit score and loan size. See our breakdown of what PMI really costs in Arizona for the range.

Run your own numbers

What you give up

Physician loans are not free money. The tradeoffs are real, and they are the reason I run both options for every doctor who calls.

• A bigger loan and thinner equity. With 0 to 5% down you start with little cushion. If values in your zip code soften, you can owe more than the home is worth for a while. That only hurts if you have to sell, but doctors relocate for fellowships more than most buyers.
• The rate or fees can run higher. Lenders often keep these loans on their own books and price the risk. Some charge a higher rate than conventional, some charge fees, and some price close to the market. The only way to know is to compare a written quote on each.
• Tighter limits on the property. Many programs cap the loan amount, require a primary residence, or restrict condos and multi unit buildings.
• A larger monthly payment. Zero down means a bigger principal balance, which in the table above is about $272 more a month in principal and interest than the same 5% down loan.

One more thing doctors tend to miss: reserves. Many physician programs ask for a few months of payments in the bank after closing, and a lender may count retirement accounts only at a discount. On an $800,000 home, three months of payments is more than $16,000 sitting untouched. If you are a resident, that cushion is often the real limit on how much you can buy, not the loan itself, so ask about it on the first call.

The Valley adds its own wrinkle. Arizona homeowners insurance has been climbing, and a pool, a roof, or an older system can change the true monthly cost. Our guide to homeowners insurance in Arizona explains why, and you can compare listings and days on market in Homes.com's Phoenix Housing Market Reports before you decide how much house to chase.

Steps for a resident or new attending

The order matters more than the program. A short sequence keeps you from losing a contract or an approval.

Start with a conversation about your timeline, not a rate. Tell the lender your start date, your contract terms, and your loan balances up front. Get pre-approved on the physician product and on a conventional option so you can compare them side by side. Our guide to getting pre-approved in Arizona covers what to bring. Then shop homes inside the number you are comfortable paying, not the maximum number you were approved for.

When you are ready, our process page shows what the first 48 hours look like. If you are still choosing a home, current listings are at Arizona Luxury Property Search, and the team at Pillar Mortgage Group can price a physician program next to every conventional option we work with.

Honest caveat: this is the wrong move if you have 20% down and a clear plan to stay for a decade, because a conventional loan with real equity is cheaper and safer. It is also wrong if you are likely to leave Arizona within two or three years for a fellowship or a new job, since closing costs and thin equity can eat the benefit. And if you are stretching to buy at the top of your approval, the zero down feature can hide how much house you can really afford.
