I think a good starting point would be looking at the comps in your area (recently renovated or new construction homes) that sold around your desired sale price and in your desired timeframe and taking inspiration from there design choices. 

The structure will depend on the down payment, quality of borrower, terms of note, your cash out of the note sale needs, and other factors. 

Popular choices like Fidelity, Schwab, or Vanguard let you invest in a range of stocks, mutual funds, and ETFs.

Im literally closing a loan on Monday where my borrower had a similar situation - the borrower's ex-wife was awarded the property and assigned the debt in the divorce in 2020.

My first choice would be a duplex but I'm also looking into single family.

They’re pretty solid markets with good rental demand.As for RentRedi its a great choice for tenant screening.

A borrower really needs to have at least some "skin in the game" to make lenders feel comfortable.

You'll find much greater difference in $$$$$ by refining your location/rehab/vacancy strategies instead of worrying about "how much it costs to borrow money" in this environment.Nearly all of my clients are more concerned with a simple and headache-free funding process, than the "lowest rate."

The Act specifically prohibits lenders from enforcing the due-on-sale clause when a residential property of less than five units is transferred into a revocable trust where the borrower is a beneficiary.2. 

Some, but not a lot of choices are rare do any of the prices make sense to me.
