Can I use my "Subject-To" cash flow to qualify for a mortgage?

[Kavon I. Simmons]

I'm a New Jersey investor and I've been utilizing the "subject-to" existing strategy for about 3 years. This year (2021), I acquired more properties to my portfolio. I owner finance ALL of my subject-to properties out on 15 to 30 year mortgage terms to tenant buyers. Now, I'm looking to take all of my cash flow and buy a property traditionally (leaning towards a 203k at the moment). All of my contracts with the original owners and my tenant buyers are well documented and notarized. Am I able to show my "cash flow" to a mortgage lender to qualify for a mortgage?
