I probably spend at least 2 hours of my day checking Facebook, surfing the web, or watching Naked and Afraid.  

Large broker web pages like Marcus and Millichap, CBRE, ARA, Colliers, etc are also good.

Unless you're pretty tech, web, and programming savvy, the explanation I could give you wouldn't mean much.

Does anyone know a good free or paid web site for finding local single-family residence foreclosure, pre-foreclosure, auction and REO opportunities.

I've tried looking online but it doesn't seem to be something that is mentioned on companies Web sites.

According the the accessor's web site, the property property sold for $227,250)  I'm asian with a very asian name.

Look at Zillow, Craigslist, but particularly web sites for property managers because they tend to know the market best.

just go to zillow and click on the tax assessment link...it works in most counties...if that doesn't work, just go to county Web page or state department of assessment and look it up there...in Montgomery County Maryland for example I just do a Google search as follows...Montgomery County property tax search and it gets me directly to the link...in it you can search the address and it will display the owners name and mailing address, send all your mail there...if it gets returned, you have to try and find out who is in charge...always leave a note on the property...info case someone finds it...
