Put in about ten grand and a summer's worth of weekends in sweat equity and the deal is very sweet.

I'm in the same boat for reference- I bought into the "buy now, refi later" idea and am sitting on a 7.375% on my latest property acquisition and a commercial line of credit I have is at prime + 1 (so 8.5%).

A break even into a profit, and a profit into a windfall. 3- Capital - I used to state this as access to capital, back when the rules were loser, the regulations less onerous, and information less readily available.

ALWAYS ensure the contractor walks the property with you or the realtor and a CLEAR scope of work is defined.
