Paying back private lender
So I was told the best way to borrow money is from a private lender. That person told me that if I was flipping homes to pay back the private lender in a lump sum after selling it. I was wondering what everyone elses plan was to pay off a private lender. Whats the common and best way?
Also what if the private lender gave me money for a rental property? Would I pay him/her back once I start getting cashflow? Thanks!
