Buying a condo turned duplex

[Ryan Smallegan]

I am looking at buying a condo in a development that was foreclosed on and is being rezoned for single family homes. There were only 2 condo units developed in this neighborhood of approx 50 available lots. I have heard warnings about making sure the title is in good shape or no bank with touch it but I have to be honest, I don't full understand what non warrantable means. It is currently still listed as 2 pieces of property (it is a 2 unit condo/duplex) What are the questions I should be asking of the seller regarding the status of the property?

Thanks!
