Prepaid rents,and possibly ownership of things such as appliances by tenant.

Prepaid taxes and insurance, any lending fees, points, surveys, settlement fees etc

Might be a little lower than a purchase, but you will still be paying lender fees, title fees, escrow fees and prepaid items. 

Out of their Mom's basement and porn hub subscription paid by prepaid debit cards.  

I know of a company that went through a broker like this and the broker connected them with someone That ended up having a pretty bad history and the borrower wired millions after paperwork was signed for “prepaid interest reserve” and now, while they got the judgment, the money was sent overseas and it’s most likely long gone.

Possible, yes, but you'll be looking at $5k-$6k in lender fees plus title fees, prepaids and escrows and a higher rate. $75k is a little easier to find and slightly lower rates/fees. 

Yes, rates are high, but dollar for dollar there are many positive and cash flowing investments to be found, or...made.A tactic I've been utilizing for buyer(s) recently is the deployment of seller concessions in the form of seller(s) contributions towards buyer(s) closings costs, pre-paids or interest rate buy downs. 

@Kristen NegrottiI have done this once before but charged 15% interest and 5 points and all interest was prepaid - basically what I am getting at is if someone does it, it is going to be very very expensive.
