I am local and could even view in person to get a real time experience if you like. 

At least that way I can use some of the cash flow to save for a personal residence.Any advice/perspectives on how I should approach this?

Personally, I like the all-in-one units but they are expensive and poorly suited for larger units where it will take forever to get a load of laundry done (since you can't move the clothes from the washer to the dryer).

Next day another person calls in, just repeating what I said the day before in a dumb way and eventually said, you know you have to refinance the 1st mortgage, right?

I’ve been chatting with a fund manager about our performing notes.He asked a question I hadn’t heard before...Would we be willing to buy any loans back if the borrower goes 90 days delinquent?

Personally, I would do the research first, get all the answers confirmed and then look into the market to do a deal.
