Don't get too excited about this one. The price is wrong in Realty Trac. It's probably a second lien, not a first and may never come on the market. Prices in La Villita for single family homes will be about 3x this amount or more. There are a couple of foreclosure townhomes about $200,000.
Let me know if you're interested. When the addresses are not published, they're likely not on the market and might not ever be on the market.
