Scaling a Texas Rental Portfolio: Past 4 Doors, Past 10, and Beyond
Program and regulatory figures verified July 24, 2026. Details change; confirm your scenario with us.
Every Texas portfolio hits the same three walls: the conventional property-count cap, the reserve requirements that climb with it, and tax returns that stop telling the story. Each has a clean answer.
How many financed properties can I have?
Ten, conventionally. Fannie Mae's B2-2-03 allows up to 10 financed properties per borrower when the new loan is on a second home or investment property (DU-underwritten). The "you can only have four mortgages" claim you'll still hear at meetups describes policy that ended in 2009. What does climb as you grow is the reserve requirement: additional reserves measured against the aggregate unpaid balance of your other financed properties: 2% with 1–4 financed properties, 4% with 5–6, and 6% with 7–10. Additional eligibility standards also tighten as the count rises, so files at 7+ want clean credit and organized documentation.
Past ten (or well before it, once returns and reserve math get heavy), DSCR takes over. No agency property-count cap exists on DSCR programs; each property qualifies on its own rent-to-payment ratio. Our usual sequencing for Texas investors: conventional while it's cheapest and your tax returns cooperate, DSCR from there. The comparison mechanics live in the DSCR guide, and the entity structure most portfolios adopt on the way is in the LLC guide.
The 2–4 unit lane
Duplexes through fourplexes are still residential financing (one loan, one address, multiple rent checks), and Texas's big metros have real inventory of them around the medical centers, the bases, and the older streetcar neighborhoods. Plan on 25% down as the common floor on investment 2–4 unit, whether conventional or DSCR. The 2026 conforming limit is $832,750 for one-unit properties in every Texas county (no Texas county is high-cost); 2–4 unit limits run higher on FHFA's published table. On the DSCR side, all units' rent counts toward the ratio, which is why a fourplex often clears 1.0 where a same-price single-family doesn't.
Foreign-national buyers of Texas rentals
Texas rentals draw international capital, and financing exists for it: DSCR-style foreign-national programs require no U.S. credit score or Social Security number on many structures. Expect 25–30% down, reserves on the deeper end (6–12 months), and foreign bank assets documented rather than moved. An ITIN is sometimes needed for tax administration, not for qualifying; your CPA handles that side. The property still qualifies on its rent-to-payment ratio like any other DSCR file, and title can vest in a U.S. entity: the usual structure pairs a Texas LLC with a foreign member.
Portfolio practice notes from our Texas files
Three habits that keep scaling smooth. Keep leases, insurance declarations, and tax bills in one folder per property; reserve calculations touch all of them at every closing. Watch the property-tax reassessment on each acquisition (the circuit-breaker cap helps through 2026, then may not). And protest appraisals annually; on a ten-door portfolio at big-metro tax rates, a few successful protests fund a down payment over time.
No pressure, no obligation, and no salesy follow-up: a 20-minute call with our team, real numbers, and a straight answer on whether the deal pencils.
Frequently asked questions
How many financed properties can I have with conventional loans?
Up to 10 per borrower under Fannie Mae B2-2-03 for second-home and investment purchases. Reserve requirements climb with the count: 2% of the aggregate balance of your other financed properties at 1–4, 4% at 5–6, and 6% at 7–10. The four-property limit people still cite ended in 2009.
What happens when I hit the 10-property cap?
DSCR financing takes over: no agency property-count cap exists, and each property qualifies on its own rent against its own payment. Many investors switch earlier than 10, when conventional reserve math and tax-return documentation get heavier than DSCR's simpler file. The crossover point is a numbers question we can run for your portfolio.
How much down do I need on a Texas duplex or fourplex?
25% is the common floor on investment 2–4 unit property, conventional or DSCR. In exchange, every unit's rent counts toward qualifying; on the DSCR side that multi-unit rent roll often clears the 1.0 ratio where a same-priced single-family can't. The 2026 one-unit conforming limit is $832,750 in all Texas counties.
Can a foreign national buy Texas investment property with financing?
Yes. Foreign-national DSCR programs on many structures require no U.S. credit or Social Security number; plan on 25–30% down and 6–12 months of reserves, with foreign assets documented. An ITIN may be needed for taxes rather than qualification. Title typically vests in a Texas LLC.
