Can a townhouse or single family unit work for living and renting

[Robert McCormick]

I'm a landlord/property manager for 2 condos in San Antonio TX and am currently looking into one more place to get for multiple purposes.
My family and I are looking at townhomes, single family, and duplexes within the city with the idea of me moving into it and potentially renting out the rest of the place. I know duplexes are the best bet for someone wanting to live in one spot and then renting out the other unit within the complex but our search has made it seem that there aren't many multifamily/duplexes available in the area. I'm going to keep searching but am curious if anyone has had any luck with living in a townhome or single family and renting out another part of it to a tenant? If so great as it makes our search easier but if not I will consider other ideas. All answers and suggestions are appreciated!
