Many looking to rent an apartment in Houston might be having a hard time — and for those wondering why, Rent Cafe offers an answer in its end-of-the-year report on Texas' most-competitive rental markets.

In San Antonio, renters are mainly staying put, renewing their leases into 2023. According to Rent Cafe, about 56 percent of renters and apartment dwellers opted to stay where they were. That's creating a tight squeeze for would-be renters; for every available apartment, there are, on average, 12 renters vying to live there.

Rent Cafe also indicates that apartments in San Antonio fill up within 31 days and the overall apartment market finds itself at about 94 percent occupancy.

That's great news for rental property owners, even as it's likely causing stress for those looking to find new digs and aren't interested in home ownership.

Turns out, though, that San Antonio isn't actually the most competitive rental market in the state. That honor goes to El Paso, where there are 15 renters looking for every available unit. And available apartments in Sun City stay vacant for only 28 days.

In Austin, Dallas, and Fort Worth, would-be renters are also finding things difficult. In Austin, 12 prospective renters are vying for every available unit, and those units stay vacant, on average, for only a month before someone else signs a lease.

In Dallas, there are 14 renters for every available unit, and those who spy a vacant apartment better grab it fast. Rent Cafe says the units in Big D stay vacant for only about 30 days, which is also the story in neighboring Fort Worth, where 13 prospective renters compete for every available unit.

So, why can't Texans find apartments in Texas? Blame supply and demand. There are more people looking to rent than are places to rent. Even though Austin increased its share of rental units by nearly three percent this year and Houston upped its supply by two percent, it's still not enough.

"Markets in Texas continued to attract out-of-state renters looking for better job opportunities and a more affordable lifestyle," read a summary of Rent Cafe's report.

The bright side to all of this? We're not Miami. The Florida city topped Rent Cafe's list of most-competitive markets, where 32 prospective renters are competing for every available unit.

Looks like the moral of the story is, Houstonians should be prepared to sign on the dotted line once they find that spot they love.
