Niches for private lending

[Marcello Spagnuolo]

Hi everyone

I am very new to real estate investing and I have a question about raising private money and how agreements are structured. From what ive learned, private lenders are looking for the quick return typically (1-3 years). My question is what niches (real estate projects) do investors typically jump into with private lenders taking into account that a lenders capital raised to fund a project must be paid back in a short span? Are only rehab and house flips considered? Does anything long term like a multi family rental work for a private lender as well as the investor? I ultimately thought of an idea to flip and rent but have no clue how I would structure a deal for a lender so that it works in there benefit as well? need help? any information on the topic would be greatly appreciated.
