It is a lender out of Madison that I found some favorable terms with, potentially 15% on an investment loan, and they might be able to wrap in the repair loan as well, Josh Nelson, you can find his info online.

I'm Watching a quick clip of Grant Cardone on youtube saying we need to be online, the best marketing tools are sites like facebook and Instagram.

They are publicly accessible in almost every county. 

They promised access to private lenders that lend based on the deal and not someones credit.
