I've just started exploring multi-family opportunities in Houston (not my home base), and I've seen a number of properties that are four-plex buildings as part of a larger development. The average HOA fee seems to be about $750/month for all four units. The fees seem to cover maintenance of the things you'd expect like grounds maintenance, and exterior maintenance including the roof. Does this also include the building structure and building systems like electrical, plumbing, and HVAC? Are these typically fee-simple ownership of the land and improvements or some other ownership structure? Also, how are property taxes in Texas calculated? I know it's a lot of questions, but I'd appreciate input from anyone with experience investing in TX. Thanks.
