Any tips would be appreciated, and I look forward to interacting with you all.Sincerely,Nolan

I have not had any borrower that has taken advantage of this loan yet, however it will be a bit more involved than closing a regular purchase or refinance, due to the rehab bids and construction elements of the loan.
