As my peers suggested, you have several options depending on your criteria.
When you mention affordable, a bottom-line budget would help us to recommend cerrtain areas. Since Houston is such a vast area, you will also want to consider your commute to and from your office. Katy, Sugar Land, Spring, etc. blend in with Houston, so those are additional choices.
Ultimately, the availability, the price range, type of home (beds, baths, etc.), will determine what you can choose from. We would love to give you recommendations, but some more information would be very helpful. When are you looking to move into Houston and what is your time frame to get into the new home. Are you looking to purchase right away or rent first. I help with Apartment rentals as well, so please let me know what I can assist you with.
