I am thinking of paying cash with the hopes of delayed-refinancing the properties or some other option to pull my cash back out. 

Marcuss & Millichaphttp://www.marcusmillichap.com/Also here in Georgia you can pull up the MLS website and screen just for multi-family.

If it was the actual owner and there were some shennanigans on the notice or process, then maybe they could delay it or something.But there's no way the bank can pull that.

You need a ton of them to add up to the cash flow needed to quit working full-time, and then honestly, most people realize the value of putting those cash flow gains back into their portfolios and understand the value of keeping their day jobs as long as they can to not pull money out of their properties. 

I pulled up the carpet (thank God there were hard wood floors underneath).

On educated guess, they did not inspect each and every building and built a list, they might pull the data on certain types of buildings, but the list might not be released to the public.This is good news for me as I do foundation work, too bad for owners who need to spend money to do it, I'm sure there will be a program from the city/state that will help aid the expenses again.

Zillow is a good starting point, but like James said, you need real comps pulled by a Real Estate agent.  

I would go to an agent and ask them to pull a list of cash buyers.

That would have been my gamble had I had the money and pulled the trigger.

Keep at it, and make sure you do all your education now, so when youre ready to pull the trigger on a deal, then you actually will pull the trigger
