Cities generally do not have HOA dues. HOA stands for Home Owener Association. This is an organization of homeowners that are usually formally on file with the county to preverve property values within a certain geographical area, usually a subdivision, via deed restrictions. Subdivisions are, therefore, what you want to look for. Different subdivisions have different deed restrictions and dues. They vary greatly from $20/year to thousands/year. Cities, such as Houston or West University, will have building codes and maintance codes instead of deed restrictions and HOAs. Sometimes there are both city codes and deed restrictions.
So, if you are looking to AVOID deed restrictions or building and maintance codes, look for property that is not in an incorported city, and NOT in a subdivision. There are plenty of areas, mostly in the North East part of Harris County. If you need help, please contact me.
