Call me lazy but I don't really have the time to cold call the hundreds of banks (https://www5.fdic.gov/idasp/main.asp) to see if they have a portfolio loan program works for me in the markets I invest in.

There are many "first time" (not having owned a home in 3 years) buying programs that offer assistance with downpayments as well.  

There I worked heavily with single family housing development (rental and for sale), down payment assistance program, acquisition/ rehab of abandoned properties, and overall community development.  

Although it is a federal program the offices are run locally and with different rules. 

In short, the programs you are talking about are "First Time Home Buyer" programs. 

I'm also waiting to get into the Radiology Program at Fresno City but in the mean time I'd like to get involved with Real Estate.

Frustrated with the system and the homeless rates of former foster youth, I developed my own program to improve those outcomes.

Is there any special mortgage program for public school teachers in Georgia?

You are only a first time buyer once. there are a lot of programs for first time buyers  where you can put very little money down. if you buy the right property you could potentially  live therefor free buy having your tenats pay the mortgage. 

Go and talk to local bankers and you government officials about programs that they may or may not have.
