When they can see you manage positive cash flow on these investment properties, they would be happy to step in and help you purchase additional properties.

And 6-8% for 20 years while still getting the tax deferral of the 1031 and stepping out of the overheated market might not be the worst thing. 

I haven’t bought anything using this method yet but everything is in motion.

I get a lot of these junior purchaser's sitting across my desk asking for the previous note, of the previous owner, on my existing senior lien, thinking that they are stepping in as the former owner (They aren't and I don't give them anything more than total debt payoff).

It sounds like it is above the price point you are targeting, but it may give you some ideas based on the house-hacking method we used as an alternative to buying a multi-family! 

I have this deal I want to finance using owner finance.After I get the contract signed what’s the next steps? 

But they were simply to easy to approve my business model which was not just vanilla flip loan. ( keep in mind I have been a HML for decades so I know the industry plus I am NMLS licensed mortgage banker )  but anyway they were just too quick to say yup your approved send in 10k for due diligence to go to the next step..

Correct with one additional step - If 1031 is still around you can bet I'll be also. 

It offers tangible actionable steps to scale your business.

Highly recommend getting on the phone and seeing how you can lend a hand (connect buyers and sellers, educate owners on CASH program, educate on tax deferral methods, etc.)
