You could partner and offer a preferred equity position (i.e. payment of a set interest rate on a monthly basis + some type of fixed annualized return when you either refi or sell).But with either option, which are your most realistic options for this deal, you will have to show some significant upside.  

I’m interested in buying lower priced properties & selling them for a quick turn around time.

"I price my product to sell.

I've had issues with this tenant in the past, as discussed in a previous post.Currently, I'm concerned that my tenant might have a drug problem, as he seems to never sleep.

Sell it and buy another property or BRRR?

My fiance has a family member that is willing to sell us a house for way under its current value that she inherited from her adoptive mother, who passed away a few years ago.

Look for military and civilian workers selling their homes, for transfers out of town, or trade ups for bigger homes. 

I read an article where on agent predicted nothing will change because all the settlement stops is mandatory buyer's fees, so all the selling agents will just convince sellers to still include them so that they get the most opportunity to sell their house.

I can't exactly report it as a disposition because I'm not selling my home. 

The idea is to create cashlow and wealth through equity and appreciation so the plan we can build few units , sell them and split profit 50/50, while I am the boots on the ground overseeing the process of building from start to finish, meanwhile the partner brings 100% of funding.
