I love you and appreciate you for reading it haha.So given the current situation we're in all, realistically all that we can do is find a SFR live and flip situation that we occupy for a year and resell as an exit strategy.If you have anything to add even if you don't think its helpful please post it anyway because maybe it'll get our brains stirring in some way. 

your job is to either get them paying again once you buy them or  foreclose and become the owner then resell or rent.2. there are note funds that will buy NPN and performing notes and do all the heavy lifting for you.. usually need to be accredited @Mike Hartzog has such a fund. 

How do I keep the seller-finances mortgage active even after I resell the house?

Then resell or refinance it at $2 mill Your Return would actually 100% Return on investment-- $1m capital invested with $1mill roiJust throwing out simple numbers.I've made 100% returns on flips in the past and often hit about 30% to 100% IRR

My goal is to buy the property via lease option purchase and then resell it with a lease option purchase and cashflow while waiting for the new buyer to qualify for a loan.My concern is that the monthly payment could eventually exceed my cashflow.My original thought was that I set a fixed monthly rent amount in my lease purchase agreement with the seller, and anything above that is his responsibility.But my concern with that is what if he doesn't continue to pay the mortgage?

title insurance is like any other insurance you only need it when you acutally need it.I have a access claim going now 3 years probably 50k minimum title company has spent ..just the cost of doing business.Only time i would consider not buying it is say a tax sale or other very cheapo type properties that i had no intention of borrowing against or reselling.. buy and hold forever and then dispose of when done.

It’s intimidating to say: I want to purchase a property and fix it up and resell it.

They will try to resell it as an assignment. 

Each time you resell the home you get a new down payment. 

At the point you are in a position to resell the note as a re-performer, there would not appear to be any arrearage.
