I don't think you would typically include the opportunity cost into your return on investment, but it's definitely a good thing to look into.  

Welcome Berny to BP, I'm also an experienced investor and mainly look for deals North of Buckhead and the Northwest quadrant including Cobb, North Fulton west of 400, Bartow, Cherokee counties.

I think this is twofold, one because the prices have been driven very high (and I'm late to the party) and the FHA payments usually are also higher (including insurance, etc.), and two because it's difficult to get the FHA loan on a property that is 70-80% and needs repairs, so nothing from my current wholesaler contacts would work. 

First off, you should get with either Keller Williams or Coldwell Banker, they are generally regarded as the largest/most successful brokers in San Diego, but if you find a good mentor elsewhere and can get some 1 on 1 attention starting out, that's good too.

Have you included a vacancy rate into what you will Net over the year?
