Investment Condos & Non-Warrantable Projects

Agency rental-income rules, DSCR math and real-world investor financing without mixing them into one generic rule.

Borrower strength cannot fix project ineligibility

An investment borrower may qualify personally while the condo project fails agency requirements.

Agency project review

Insurance, critical repairs, litigation, budget, ownership/concentration and project characteristics can affect eligibility.

Private alternatives

Non-QM/DSCR investors may finance some non-warrantable condos, but LTV, reserves, project exposure and pricing vary.

STR overlay

A condo used as an Airbnb can add rental, project, hotel/resort and HOA-use restrictions at the same time.

Investor underwriting checklist

Identify occupancy, unit count, purchase/refinance/cash-out purpose, current ownership/title, financed-property count, current PITIA on every retained property, leases, Schedule E history, acquisition dates, reserves, entity ownership, short-term-rental use, condo/project status and the exact agency or private-investor program. Rental income should be calculated only after the property is placed in the correct underwriting category.

Where experienced analysis matters

A deal can fail because the wrong rent document was used, positive rental income was treated too generously, reserves were calculated incorrectly, an LLC mortgage was counted incorrectly, a newly acquired rental was analyzed under an older rule, or a private DSCR overlay was presented as if it were a Fannie/Freddie requirement.

How I would underwrite the scenario step by step

1. Identify agency conventional versus private DSCR/portfolio financing. 2. Build a complete real-estate-owned schedule with ownership, mortgage obligation, PITIA, rent, acquisition date and entity vesting. 3. Determine the permitted rental documentation for each property. 4. Calculate each rental separately under the applicable rule. 5. Count financed properties and calculate required reserves. 6. Review property/project eligibility, LTV, credit and cash-out/seasoning. 7. Only then compare pricing and decide which loan structure best fits the investor's strategy.

This sequence prevents a strong-looking property from being qualified with the wrong income methodology. For investors with several rentals, one incorrectly treated property can change DTI, reserves, financed-property count or even product eligibility.

MortgageDadOf3 rule: First identify whether this is agency rental-income underwriting or a private business-purpose investment loan. Then calculate it under that exact framework.
