These were largely sourced pre-CV19, so eat the fish and spit out the bones.The DTI percentage range varies by lender, and is less than what you will find for an owner occupied property, due to lender risk.

We have plenty to offer here in that range in Oklahoma.

So, looking at the flips I take on, with anticipated profits in the $70k+ range, the setup costs alone are eating nearly 20% of your potential profits, and that is before any real splits with your investors, leaving both your investors and you with not a lot of money left to spread around.A fund could work, but typically, for the economics of a syndication/fund structure to work, you are looking at several million of equity, leveraged up to high single millions, if not into $10+ million range for their to be enough money to make it worth everyone's efforts.
