Income Documentation

How underwriters calculate, verify, and qualify non-standard income types: trust distributions, IHSS, RSU vests, commissions, overtime, and more.

IHSS Income

IHSS Income and Mortgage Qualification: What Most Lenders Get Wrong

In-Home Supportive Services income qualifies for a mortgage under Fannie Mae and FHA guidelines, but almost every lender mishandles it. The live-in caregiver tax exemption changes the entire documentation path.

Trust Income

Trust Income Mortgage Qualification: How Underwriters Really Evaluate It

Read the guide
Commission Income

Commission Income Mortgages: The 25% Rule and the Documents That Make or Break Your File

Read the guide
Overtime Income

Overtime Income and Mortgage Qualification: The 24-Month Averaging Rule

Overtime income qualifies for a mortgage, but only with a two-year history averaged correctly. The rules for declining overtime income are strict, and the employer letter requirement catches many borrowers off guard.

Read the guide
RSU Income

Read the guide
Self-Employed Income

Self-Employed Income Analysis: Add-Backs, Business Returns, and the Math Lenders Get Wrong

Read the guide
Social Security Income

Social Security Income and Mortgage Qualification: Gross-Up, Survivor Benefits, and SSI vs SSDI

Read the guide
Rental Income

Rental Income Mortgage Qualification: Schedule E Analysis and the Vacancy Factor
