Documentation and Reserves
The offer letter and the reserve requirement both have to hold up.
Fannie Mae’s guidance is specific about what the offer must document and what extra funds a borrower needs on hand until the paychecks start.
Which properties qualify
The option that lets a lender deliver the loan without a paystub in hand applies to a purchase transaction for a one-unit principal residence, using the borrower’s fixed base pay from the new position (Fannie Mae Selling Guide B3-3.1-09, Employment Offers or Contracts, updated Mar. 4, 2026).
What the offer or contract must show
The document must be signed by the employer and the borrower, name the position, the pay, and the start date, confirm that all conditions of employment have been met, and support lender verification of the offer’s authenticity.
The 90-day start-date limit
When the job starts after the loan closes, Fannie Mae requires the employment to begin no later than 90 days after the note date. An employment start date farther out than that falls outside this option.
The added reserve requirement
Beyond any other reserves the loan already requires, Fannie Mae requires either six months of the borrower’s PITIA (principal, interest, taxes, insurance and association dues), or enough documented financial reserves to cover the borrower’s monthly qualifying debts until employment begins, plus an additional one month of those debts.
