what is typical for a down payment if someone owner finances?

If I buy property A using conventional loan with 20% down payment, 5% of purchase price as closing cost estimate and $7K in repair, I'm looking at out of pocket cash of approximately $30K.

It would most likely trigger the due on sale clause.A scenario that may work though is if the amount remaining on their mortgage is less than what you are willing to offer as a down payment or they were willing to pony up the difference.

So the $700 payment on a home that rents for $1200 is still a decent cash flow.

We are going to use this cash flow to pay down the HELOC we use for down payments so that we can buy more houses sooner.

Repayment would be the interest-onlyOption 2) If you were wanting to use the proceeds towards a down-payment of a rental house.
