Physician Mortgage with an Offer Letter — How to Close Before Your First Day

The offer letter mechanic is unique to physician loan programs because it requires the lender to make a credit decision based on future income rather than documented past income — something Fannie Mae and Freddie Mac guidelines explicitly prohibit for conventional products. Physician loan programs are portfolio products held on the lender’s balance sheet, not sold to the secondary market. This means the lender sets its own underwriting standards and can make a relationship-based credit decision that recognises the physician’s earning trajectory rather than just their current documented income. The offer letter mechanic exists because the lender is comfortable with the credit risk of a physician who just completed training and has a guaranteed job — a risk profile that conventional guidelines were not designed to accommodate.

Fellowship to Attending: The Most Common Offer Letter Use Case

The highest-use offer letter scenario: a physician completing fellowship at Institution A signs a contract to join a practice at Institution B, starting in 60 days. They are currently earning fellowship income ($80,000). The new contract shows attending income ($450,000). A physician loan lender using the offer letter can approve the loan based on the $450,000 attending salary even before the physician completes fellowship. The practical result: the physician can close during the transition period between fellowship completion and the first attending paycheck, arriving in the new city in a home they own rather than scrambling for temporary housing.

Why This Feature Exists Nowhere Else in Mortgage Lending

The offer letter mechanic is unique to physician loan programs because it requires the lender to make a credit decision based on future income rather than documented past income — something Fannie Mae and Freddie Mac guidelines explicitly prohibit for conventional products. Physician loan programs are portfolio products held on the lender’s balance sheet, not sold to the secondary market, allowing each institution to set its own underwriting standards. The lender is comfortable with the credit risk because the physician’s earning trajectory is predictable and verifiable: a signed contract at a hospital or group practice is a genuine employment obligation, not a conditional offer.

The Fellowship-to-Attending Transition: Offer Letter Use Case

The most common offer letter scenario: a physician completing fellowship at Institution A signs a contract to join a practice at Institution B, starting in 60 days. They are currently earning fellowship income ($80,000). The contract shows attending income ($450,000). A physician loan lender using the offer letter approves the loan based on the $450,000 attending salary, not the $80,000 fellowship stipend. The physician can close during the transition period — during the overlap between fellowship completion and attending start — arriving in the new city in a home they own rather than scrambling for temporary housing. This scenario plays out thousands of times each year; the offer letter mechanic makes it financially efficient in ways that conventional lending cannot.

FAQ

What exactly makes a physician offer letter acceptable to a lender?

For a physician loan to close on an offer letter rather than paystubs, the letter or contract must typically contain: the physician’s name and professional credentials; the employer’s name and address; the start date (within 60–90 days of closing at most lenders); the base compensation amount (annual salary stated explicitly); employment type (W-2 employee, not independent contractor); and duration (permanent employment, not a locum or short-term contract). An offer letter that says “we are pleased to offer you a position” without specific compensation details will not satisfy underwriting. The signed formal employment agreement or contract is stronger than a preliminary offer letter.

Can I use an offer letter if I’m starting as an independent contractor (1099)?

No. The offer letter mechanic applies specifically to W-2 employment. A physician starting as a 1099 independent contractor — common in locum tenens, some emergency medicine positions, and some private practice arrangements — cannot use a physician loan offer letter mechanic. The 1099 physician is treated as self-employed and requires either two years of self-employment income history (conventional) or a portfolio lender (locum tenens guide). If you will eventually convert from 1099 to W-2 (some emergency medicine and hospitalist positions), wait for the W-2 conversion before purchasing.

What if my offer letter shows a lower base salary because most of my compensation is variable?

Some attending physician compensation structures are primarily variable — production-based, RVU-based, or procedure-based — with a modest guaranteed base salary. A contract showing $150,000 base + variable production (where actual compensation will be $400,000+) will qualify the physician for the mortgage at the $150,000 base only, not the total expected compensation. Physician loan programs generally cannot count production-based variable income that is not guaranteed. This is a common frustration for surgeons and procedure-based specialists whose real income significantly exceeds their contractual base. The solution: wait for 12–24 months of documented production income before purchasing above the base-salary qualification level.

What is the maximum purchase price I can close on with an offer letter?

Purchase price with an offer letter depends entirely on the base salary shown in the contract and the physician loan program’s maximum loan amount. At a $400,000 base salary with a 43% DTI, approximately $2,400,000 in total debt service is supportable — but physician loan programs typically cap at $1.5M–$2M for 0% down. For new attendings purchasing above those limits, a conventional jumbo with an offer letter (30-day start window) or private bank lending is required.
