Most new attendings assume the rules of home buying are the same for them as for everyone else: save 10–20% down, pay off some student debt, wait until you have a couple of years of W-2 history, then apply. For the vast majority of borrowers, that's correct. For physicians and dentists — and increasingly for pharmacists and other high-income medical professionals — there is a different path, and it opens up earlier than most people realize.
The physician mortgage (sometimes called a doctor loan) is a specialty product offered by portfolio lenders. Because the lender keeps the loan on its own books rather than selling it to Fannie Mae or Freddie Mac, it can underwrite to rules the agency market doesn't allow. The most important of those rules, for a resident or fellow, is that a signed employment contract can serve as proof of future income — even if the job hasn't started yet.
What "future income" actually means in underwriting
For a conventional mortgage, a lender generally wants to see two years of tax returns and a stable earnings history in the same field. That standard makes sense for most jobs, but it's a poor fit for medicine, where someone can spend a decade training on a stipend of $60,000–$80,000 and then, on a specific date known months in advance, begin earning four to eight times that amount.
Physician mortgage lenders solved this by treating a signed employment contract — or sometimes a match letter — as an equivalent to a pay stub, as long as the start date is close enough to closing. The cutoff varies, but most programs will honor a contract dated within 60 to 120 days of the closing date. A few will go out further. This means a fellow finishing in June can reasonably begin house-hunting in March or April, tie the closing to a date shortly before the start date, and move in as an attending.
The underwriting details that matter
A few details decide whether the process is smooth or painful:
The employment contract needs to be fully executed, including salary, start date, and employer signature. A verbal offer or an unsigned letter of intent is generally not enough. If the contract contains contingencies — credentialing, licensing, a physical — the lender will usually ask for confirmation that those are complete or on track.
Student loans are handled differently than in the conventional world. A physician mortgage lender will usually accept your actual Income-Driven Repayment (IDR) amount, or exclude loans that are in deferment or forbearance for at least 12 months after closing. This is the single biggest reason residents with six-figure student debt can qualify on an attending income even before the income starts.
The down payment requirement is typically 0%–10% depending on loan size, with no private mortgage insurance. That matters because PMI on a $600,000 loan can easily run $200–$400 per month, money that disappears whether or not rates fall later.
Reserves — liquid savings held after closing — still matter. Most programs want to see at least two months of mortgage payments in the bank, sometimes more for larger loans. This is where residents most often get caught off guard.
Where it still goes wrong
The product is generous, but it isn't magic. A few patterns come up repeatedly.
Timing is the first. If your start date is nine months out, most lenders won't write the loan yet. Four to five months is usually the sweet spot. If you're earlier than that, you may need to wait or find one of the handful of lenders who will stretch the window.
The second is affordability versus approval. A lender may approve you for a $900,000 loan based on your future attending salary, but your first-year cash flow as a new attending — with relocation costs, higher taxes than expected, licensing, a CME budget, and possibly a growing family — often looks very different from the spreadsheet. It is almost always worth buying less house than the maximum the lender offers.
The third is rate shopping. Physician mortgages are portfolio-priced, meaning two lenders can quote the same borrower rates 0.25%–0.50% apart. On a $700,000 loan, a quarter point is roughly $40,000 over 30 years. Getting three to five written quotes in the same week is not optional — it is the single highest-leverage thing you can do in the process.
A practical sequence
If you're a resident or fellow considering a home purchase before attendinghood, a reasonable sequence looks like this: about six months before your start date, get your credit report clean and pull a preliminary rate sheet from two or three lenders. About four months out, once your contract is signed and in hand, request formal pre-approvals. Look at homes only in a price range that works on your first-year attending take-home — not on the approval ceiling. Close 30–60 days before the start date so you have time to move in, get the utilities on, and breathe before your first day.
The physician mortgage is one of the few financial products in medicine that is genuinely designed around how doctors actually earn. Used thoughtfully, it can turn what feels like an impossible timeline into an ordinary one. Used carelessly, it can turn a great job into a stressful first year. The difference is almost always in the preparation.
