Why does Texas only sell half duplexes as multifamilies?

[Vincent Chau]

Hi Everyone,

I am looking to househack in Texas, mostly looking at the DFW area, but am open to other cities as well. I'm looking into purchasing a multifamily house, but most of the multifamilies on realtor.com or other mls websites are sold as half-duplex. What is the reason for this? It seems to me that it would be more profitable and easier to manage if houses were in multiple units as opposed to one.

Thank you in advanced!
