You sound like you're probably headed for deep and shark infested waters on an air mattress, (LOL).Land contracts are pretty well dead in the water, two issues, one is with the new laws pertaining to seller financed transactions, if you pass a lending contract on to a buyer you're facilitating a loan assumption and doing so as a business may have consequences.

Thank you @Jim Adrian as our card fees are 2.95% for credit cards and 1.5% for debit cards so that can definitely add up but I see @David Dachtera point about collecting the rent by any means possible.You have to be careful as some states do not allow you to pass a "surcharge" to the tenant for using a credit card instead of paying by ACH.

There isn’t much to be made in terms of commission so many loan officers don’t want to mess with them, and any loan is going to have fees associated with it of course…how high the lender’s fees are and how low the loan amount is will factor into whether or not that loan is compliant and can pass as a qualified mortgage.
