I agree with the previous answers - your best bet is going to be to work with a Realtor. They can do the hard work for you! They'll have to sift through answers much like you do, but they'll have more search options and more experience looking through listings.
One option not mentioned yet, though, is the map search tool in HAR. It would be tedious, but you could target Cypress and Katy and search that way. In a lot of cases, you can tell what's a neighborhood by the layout of the roads. If you really wanted to search yourself my advice would be to go out to the suburbs and try selecting areas that way. This is a long shot, but could be the most effective way for you to search yourself (it would guarantee that you're searching outside of neighborhoods).
But, I stand by my previous suggestion - it's going to be a lot easier to work with a Realtor! If we can be of service, please message us or give us a call. We have a Buyer's Specialist now who is searching for homes just like this for another client, so she would be great for you to work with - may even already have listings in mind!
Hope this helps,
