The LLC Loophole Most Rental Investors Don't Know They're Missing
Real estate investors purchased roughly a third of all single-family homes sold in 2025, the highest share in five years. As that portfolio-building trend accelerates, more investors are running headfirst into a rule most people don't discover until they're already stuck: Fannie Mae caps conventional financing at 10 financed properties per borrower. What far fewer investors understand is that how a property is titled can determine whether it counts against that limit at all, and that single detail is quietly reshaping how serious investors structure their portfolios.
The 10-Property Ceiling, and the Loophole Inside It
Fannie Mae's Selling Guide is explicit on this point: a borrower who owns investment properties financed in the name of an LLC in which they hold only partial ownership is not included in the financed-property count, because they aren't personally obligated on the underlying debt. Fannie Mae's own guidance illustrates this with a direct example: a borrower purchasing a second home who also owns four two-unit investment properties financed under an LLC with 50% ownership ends up with just two financed properties counted, not six, because the LLC-held properties fall outside the personal liability test entirely.
That's a meaningful structural lever. An investor building a portfolio through partial LLC ownership can, in some cases, keep approaching conventional lenders for additional financing long after a fully personal-name portfolio would have hit the wall. It's not a loophole in the sense of exploiting a mistake, it's literally written into Fannie Mae's own guidelines, but it's one most investors only learn about from an underwriter after the fact, rather than planning around it from the start.
Where the Loophole Runs Out, and What Replaces It
Even with smart titling, the math eventually catches up. Properties where you're personally obligated on the mortgage, regardless of whether rental income flows through a partnership or S-corp, still count toward your total. And once you're inside the 7-10 property range, Fannie Mae's own overlay kicks in: a minimum 720 representative credit score and reserve requirements that jump to 6% of the aggregate unpaid balances across your portfolio, on top of whatever reserves the individual loan itself requires.
This is the exact point where most growing investors start looking at financing that was never subject to the personal-property count in the first place. DSCR loans and other forms of dedicated Business Loan for Rental Property financing are underwritten as business-purpose credit, evaluated against the asset's own rental income rather than the borrower's personal debt-to-income ratio, which is precisely why they were built to operate outside Fannie and Freddie's financed-property limits entirely. For an investor who has structured several properties under LLCs specifically to preserve runway on conventional paper, transitioning the rest of the portfolio to business-purpose lending once that runway closes is often the more efficient path than fighting for a personal loan number 11.
Getting the Titling Decision Right From the Start
The mistake many first-time portfolio builders make isn't choosing the wrong financing, it's not thinking about titling until they're three or four properties in and a lender's overlay policy (which can be stricter than Fannie Mae's own baseline) suddenly puts the brakes on a deal they thought was routine. Fannie Mae's guide draws a clear distinction: personal liability on the mortgage is what triggers the count, not simply how rental income is reported for tax purposes.
Before acquiring your next property, it's worth having an honest conversation with whoever is financing the deal about exactly how the loan will be structured, whose name goes on the note, whether an LLC will hold partial or full ownership, and how that decision will affect your remaining runway on conventional financing versus your eligibility for asset-based alternatives. The Consumer Financial Protection Bureau also publishes general guidance on investment property financing structures worth reviewing if you're new to titling decisions and their downstream mortgage implications.
The Bigger Shift Underway
None of this happens in isolation. As investor market share climbs and conventional financing limits remain fixed, the structural gap between what Fannie Mae and Freddie Mac were built to finance and what serious portfolio builders actually need keeps widening. That gap is exactly why business-purpose and DSCR lending have grown from a niche product into a mainstream financing lane for anyone planning to scale past a handful of properties, and understanding the mechanics behind both the personal-property count and its business-purpose alternative is what lets an investor plan two or three acquisitions ahead, rather than getting blindsided by a limit they didn't know existed.
