The county has it accessed at 82k, but homes in the area are getting more since Spring Branch is so convienant to down town. I can send you the statistics for the neighborhood, but we do live in Houston so the question of illegal aliens is not one a Realtor can help with. We have to live by the ethics and codes of Realtors which is equal housing opportunity. You may just want to drive around the neighborhood at different times to get a feel of the neighborhood yourself. There are also websites with HPD that you can check crime stats with.
As far as the question about illegals, that is not a questions a Realtor can answer due to our code of ethics.
If you want to view homes to purchase call me and I'll help you search. Sometimes property on the internet is old or the status changes. Let's put together a plan and I will help and guide you through the processes from searching to appraisals to closing!
Call me and let's visit about your specific needs. Looking forward to helping you. Kathleen (281) 799-4002
