Rental Income

Schedule E and Form 8825 rental income — 75% market-rent rule, PITIA offset, and vacancy adjustments handled agency-by-agency.

Rental income calculations vary sharply by property type, occupancy, and program. Non-owner-occupied rentals typically use the 75% market-rent rule when no history exists; owner-occupied units often net rent against PITIA. Schedule E income needs depreciation and mortgage interest add-backs, and partnership or S-corp rentals show up on Form 8825 instead.

IncomeCalculator.com reads Schedule E, Form 8825, and appraisal Form 1007 or 1025 together, applies the correct occupancy and program rules, and returns a monthly rental income figure — positive or negative — with the math shown for each property.

What to upload

  • Personal tax returns (Form 1040) with Schedule E
  • Form 8825 from partnership (1065) or S-corp (1120-S) returns, if applicable
  • Current lease agreements for each rental property
  • Appraisal Form 1007 (single-unit market rent) or 1025 (2-4 unit) when required
  • Mortgage statements for each rental property

How the calculation works

1

Classify each property

Each rental is classified by occupancy (owner-occupied vs. non-owner-occupied), unit count, and reporting form (Schedule E or Form 8825).

2

Apply the right rental income rule

For properties with history, Schedule E income is restored with depreciation and mortgage interest add-backs. For properties without history, the 75% market-rent rule applies. Owner-occupied 2-4 units use net rent against PITIA.

3

Roll up to monthly qualifying income

Each property produces a positive or negative monthly figure, and all properties are combined into the borrower's total rental income — with vacancy and seasonal adjustments where appropriate.

Supported programs

Conventional, FHA, VA, and Non-QM. DSCR loans use rental income differently and are handled through the DSCR path when applicable.

Common questions

When is the 75% market-rent rule applied?

For non-owner-occupied rentals without a Schedule E history — typically new acquisitions — 75% of the market rent from the appraisal (Form 1007 or 1025) is used. The remaining 25% covers vacancy and expenses.

How is Schedule E rental income calculated?

Net rental income or loss is restored with depreciation, mortgage interest, insurance, and tax add-backs to reflect true cash flow, then averaged across the reporting period.

What about owner-occupied 2-4 unit properties?

Rental income from the non-owner-occupied units is netted against the property's PITIA. A positive result adds to qualifying income; a negative result increases the housing expense.

Does it handle Form 8825 partnership or S-corp rentals?

Yes. Form 8825 rental income from partnerships (1065) or S-corps (1120-S) is scaled to the borrower's ownership percentage and combined with any Schedule E rentals into a single qualifying figure.
