Same-Field Job Changes
A borrower who changes employers but remains in the same field or occupation is generally evaluated without penalty. For example, a nurse moving from one hospital to another, or a software developer changing companies, represents employment continuity in the same profession. The underwriter uses the new employer’s income for qualification, supported by an offer letter, pay stubs from the new employer, and verification of employment.
If the new position involves a change in compensation structure — for example, moving from a salaried position to one with significant commission or bonus components — the underwriter may require documentation of the new compensation terms and may exclude variable components until a track record is established at the new employer.
Career Changes
A borrower who changes fields entirely — for example, leaving teaching to start a real estate career — presents a different underwriting scenario. The underwriter must evaluate whether the new career provides stable income. If the new career involves commission, self-employment, or variable compensation, the lack of a two-year track record in the new field may result in the variable income being excluded from qualification or the application being declined .
Employment Gaps
Gaps in employment exceeding 30 days within the most recent two years require explanation. The borrower must provide a written letter of explanation (LOE) describing the reason for the gap (layoff, medical leave, family reasons, relocation) and the dates of unemployment. If the gap was followed by a return to the same employer or field, the impact is generally minimal. Extended gaps (6+ months) or multiple gaps create additional scrutiny and may require compensating factors such as significant reserves or a lower DTI ratio.
Fannie Mae’s automated underwriting system (DU) may or may not flag employment gaps depending on the overall file strength. If flagged, the underwriter must document the gap and determine that the current employment is stable and likely to continue.
Offer Letters and Probationary Periods
Borrowers who have accepted a new position but have not yet started may use an offer letter for qualification in some cases. The offer letter must be on company letterhead, state the position title, start date, and compensation terms (salary, bonus structure, hours). Fannie Mae allows the use of offer letters for qualification provided the borrower will begin employment before or shortly after closing and the income is not contingent on future performance milestones .
A probationary or trial period at a new employer does not automatically disqualify a borrower, but the underwriter evaluates whether the probationary status creates risk. If termination during probation is common in the industry or the employer’s policies indicate a high attrition rate, additional documentation may be required.
