Houston has a website site called HAR.COM and once a month I go trolling through the site to see what out there. They have all properties for sale in the greater houston area, including foreclosures, wholesdeals etc.
Once i have a list of what I'm looking for in my price range, i go and do a drive by and see if I can get in if it's empty. or I call the listing agent and tell them I'm an investor and they gladly show me every foreclosure they have.
Is there a listing of property tax rates for neighborhoods in the Houston area?
