"Typical" is a word I rarely use when describing Houston real estate ... it's an incredibly diverse market, even within restricted geographical areas.
I located five gated communities with homes for sale in Zip Code 77077. Maintenance fees range from $600 to $2400 annually, specifically $600, $875, $1134, $2100 and $2400. Prices are likewise all over the place ... $239,000 to $600,000. Square footage: 1837 to 3287. None have private pools, although three communities have facilities for residents.
I'll be happy to forward the listings, and would love to work with you to find the home that best suits your family. Please feel free to contact me. I look forward to hearing from you.
