.- These total 10 duplexes should bring in 30K gross rent per month and cash-flow about ~3-4K/month.We don't plan to use any of the cash-flow for personal expenses and after keeping sufficient reserves, we will funnel the cash-flow to pay-off existing properties.

@Jhonathan BituinJohnathan, I've really only spoken to a sales person.

Personal opinion, ive never liked dual-agency.

You area also going to get hit with 2.75 points and a 2 or 3 year prepayment penalty.My suggestion would be to take out a personal loan banks are offering personal loans now with no lien.

This approach aligns with my personal goal to recycle as much cash as possible.

Also - I am a very analytical person; scientist by profession. 

Since the new person is being added to the lease you will want to underwrite them to make sure they meet criteria and ensure they can be financially responsible.

Each person has their own risk tolerance, however what I will say is most people don't have straight cash to buy a couple hundred thousand dollar property hence are forced into utilizing hard money. 

Personally, I've been investing in mobile homes as a buy and hold investor since 2007.

Personally for me this always gave me piece of mind that IF I ever wanted to sell one of my properties that has appreciated a lot, I could move back into one for a while if I plan strategically in advance
