Their pro formas felt optimistic with providing 6% annual appreciation and property management that is only about 6% of rent so I take it with a grain of salt (they offer their own property management services but it has terrible reviews on Yelp so I would probably go with someone else). 

You didn't provide any numbers so can't answer if it's a good deal.

Wouldn't hurt to consult a tax pro just to make sure there isn't a more tax effective strategy but I don't think lending provides any tax shelter.

Additionally, it provides investors with the opportunity to add a unit on a property they already own, simplifying management since the new unit is in the same location.Finding a vacant lot is both expensive and difficult, so the ability to build, subdivide, and create new development opportunities can make financing easier.

Do they provide exclusive leads, or are they shared among multiple investors?

Allocate equity based on contributions: you provide the $235K HELOC and management, while your former boss contributes renovation expertise and labor.

Can you provide guidance on how to get started and some effective strategies?

It was all really quick, and the time to complete everything happened a lot faster than I expected (which was a good thing).I was worried at first that I had to use all the partners that Rent to Retirement had, but it was really easy for me to shop around for different lenders with different terms and rates, insurance providers, and property management company.

Purchasing a property for your child while they attend college can be a strategic investment and a great way to provide them with stable housing.
