Once the first rental works, the question becomes how far conventional financing can take you. Fannie Mae has a hard number for investors, and a set of counting rules that decide how fast you reach it. Here is the rule as Fannie writes it.
No limit on the number of financed properties you already own, except on HomeReady loans, which allow two.
Up to 10 financed properties, with the loan run through Fannie's automated underwriting system.
Extra reserve requirements also apply to second home and investment purchases, scaled to how many financed properties you will have.
One- to four-unit properties you are personally obligated on, including your own home if it has a mortgage.
Properties, not loans. A duplex with two mortgages counts once. A two-unit building is one property.
Every borrower's properties added together, with jointly financed ones counted once.
Commercial real estate, buildings of more than four units, timeshares, vacant lots, and a manufactured home on leased land financed as personal property.
Fannie Mae's own examples include a borrower who owns four two-unit rentals financed in the name of an LLC they half own. Because the borrower is not personally obligated on those mortgages, they do not count, and the borrower has two financed properties instead of six.
Holding rentals in an LLC has tradeoffs of its own, which the book discusses. The point here is narrower: for Fannie Mae's count, personal obligation on the mortgage is what matters, not ownership of the property.
To qualify for each additional rental, the rent has to work under the rental income rules. Starting with a building you live in? See house hacking a 2-4 unit.
