The Ten-Property Wall, and the Three Ways Through It

Conforming financing stops counting you as a borrower and starts counting your portfolio well before you feel like a real estate investor. Fannie’s Selling Guide B2-2-03 caps a borrower at ten financed properties when the subject property is a second home or an investment property. That ten is a Desktop Underwriter number: the guide grants it to the automated path and names no manual equivalent, so a manually underwritten file has no stated allowance to point at. The count is cumulative across all borrowers on the loan, it counts properties rather than mortgages, a fourplex counts as one, and it includes your own financed principal residence.

The reserve schedule bites before the ceiling does. On top of the reserves for the subject property, you must document a percentage of the aggregate unpaid balance on every other financed property, excluding the subject, your principal residence, anything sold or pending sale, and any account being paid off at closing: 2% at one to four financed properties, 4% at five or six, and 6% at seven to ten. On $3,000,000 of aggregate rental debt that is $180,000 of verified liquid reserves sitting idle before the lender will write property number eight. The Eligibility Matrix adds a 720 representative credit score once you are past six. Plan that liquidity into the acquisition schedule, or the eighth deal dies at underwriting for reasons that have nothing to do with the deal.

Three exits exist, and all three are in the guide rather than around it:

Principal residences are uncapped

The limit applies only when the subject property is a second home or an investment property. There is no limit on the number of financed properties when you are buying your own home — which is what makes the family-occupancy classification of section “Buying a Home for a Parent or an Adult Child” more useful than it first looks.

Debt you are not personally obligated on does not count

The count includes properties where the borrower is personally obligated on the mortgage. The guide’s own example is explicit: a borrower who owns four financed two-unit properties inside an LLC they half-own, without personal liability on those notes, counts none of them. This is the real financing argument for the entity structure of section “Buying Real Estate with an LLC”, separate from the liability argument — with the obvious trade that non-recourse commercial paper prices worse than a conforming rental loan, and that a personal guarantee puts the property straight back into the count.

Some property types were never in the count

Commercial real estate, multifamily above four units, vacant lots, timeshares, and a manufactured home on a leasehold estate carrying only a chattel lien are excluded outright, even where you are personally obligated. Consolidating eight scattered single-family rentals into one twelve-unit building removes the entire portfolio from the calculation, which is one of several reasons serious portfolios drift upward in unit count.
