Which means that they pay you a down payment and you finance the properties to them.

I am leaning toward removal because the floor is run down, the risk of increased pests or feral cats, and there is already a storage closet off the patio.

House hacking is an excellent strategy, especially with the potential to use an FHA loan to secure a property with a low down payment. 

To fund your next deal, explore conventional loans (15-25% down), FHA loans (3.5% down for house hacking), DSCR loans (based on rental income), or HELOC/cash-out refinance if you have equity.

Your seller can complain years down the road that he was "tricked" and you will be thrown into a lawsuit and investigation.

I financed the deal with a conventional loan and bought down the rate from 7.75 to 6.25.

@Felicia Vinces it sounds like you missed our Year End Live show and Podcast of "Real Estate Notes Show' where 2 15 year experience note investors break down what makes a note valuable.  

Are they going to start paying down that credit card debt, turn over a new leaf, and avoid bankruptcy for the next decade? 

You can allocate those proceeds any way you want - as equal down payments or buy one for cash and others with loans - It doesn't matter a bit as long as you use all of the cash and purchase at least as much as you sell. 

There are ups and downs with any property and there will always be variables with tenants, rents, repairs etc.
