I went to a REI class this weekend and they stated FL is a super lien state and in many cases would clear the first mortgage IF the mortgage was after July 2008.

I’d buy two multi family homes in c class neighborhood

Who knows; there are lots of reasons why people are able to pick up properties cheap. 

It's a strong C working class neighborhood and fits the niche between the B properties ($900+) and D ($500-) class.  

Well, maybe something with a 3% return in an A-class neighborhood.

Pick a solid B-Class suburban area.

Also, there is no harm reaching out to some of the larger banks you plan to use for the re-fi and pick their brain.

Also, since my cash on cash return is not stellar, should I just pick my percentage of return and just work backwards to figure out my max offer?

This is the "burned out landlord" approach where you can pick up several properties at a time... or perhaps their whole portfolio at a discount, and they are likely to understand what you are looking to do so there is less to educate the sellers on.Hope this helps... good luck!

Im ready to look into the classes and want to start saving money so I can buy what I need.
