Any suggestion on what I can do to buy this house?

It's suggested to not use modern types of mortar mix.

Thank you for the suggestion.

Any kind of tips and suggestions would be much appreciated. 

I would suggest you search for and attend a local real estate investor's meet up in your area and try to ask for clarification on your thinking. 

Top it off I'm sure I'll need a chunk of that $100k as reserves to handle maintenance and renovations.Would you guys n gals suggest I attend the auction just to see what happens or should I be prepared to bid? 

Hopefully I can find someone on BP, in a similar boat as me, to team up with!

These properties will be marketed by an affiliated prominent Real Estate firm to Ex-Pats, Canadians and the affluent South Florida boating community.

I am telling them to avoid that deal like the plague, although I have no idea where to suggest alternative financing.As for her own property, they are willing to refinance her at a slightly lower interest rate, and switch it over from 26 remaining years to 15 with lower monthly payments.  

Looking for suggestions on a good colored stain of some sort that will fill and get this passed.I really don't like doing things this way.
