If you find a new tenant, prorate any fees they pay you so you are not collecting 2 rents on the same day. 

Generally speaking, we would encourage you to screen your tenants - whether they are section 8 or not.We would encourage you to collect a deposit - whether they are section 8 or not.A tenant can certainly be a "good" tenant or a "bad" tenant - whether they are section 8 or not.Now, if you are targeting lower valued homes...there are "pros" and "cons" to doing that - whether you are renting to section 8 or not.  

I would consider looking for a 2-4 unit so you can at least occupy (1) unit and collect rent on the other unit(s) and at the 6 month mark evaluate your LTV and situation.

I would tell the attorney that if he is that impressed with his client's annual revenues and future prospects he is welcome to apply to guarantee the lease. 

You can also collect rent inside of these, direct from their bank account.

These properties are the ones that show the impressive 3x and greater price gains.

My quick math is if I'm collecting $75 more per booking at a conservative 40 bookings per year that's $3000 in extra revenue. 

His reply was that he sold the units, not the right to collect the interest.

I am currently looking at opportunities to enter into the MH/Month-stay RV park space, and am wondering if there are recommendations for rent collection software that is specifically tailored? 

I will essentially be managing the entire property/collecting rent and my friend will not have to lift a finger.
