New purchase rental or owner financing

[Paul Scammacca]

Need more experienced help.  Have 4 rentals currently cash flow 2400$ total per month. Just used my heloc from primary 100k to purchase c class 3/1. Going to have about 120k into it before trying to refi. Given rates, I an looking at about maybe 100$ a month plus after paying back heloc on cash out. I was thinking about about owner financing.  My problem is my heloc payment is on a 10 year schedule so it's around 1400$ a month.  To sell at owner financing the payment would need to be around 1400$ for the area. I want to make sure they can't refi the property as my "profit" will come after 10 years from p/I. Is this wishful thinking or how could it be structured?  Ty. Paul
