They do require these to be done on Primary Residence, and they probably do have a credit component, but may not have an income component to underwriting.

We were in a financial position where we could keep our existing home, upgrade, and purchase another home.

-there is tremendous demand for inventory among both primary buyers and investors. 

With that said, I am in the position where I will not need a monthly income from my rentals.

@John Davey Interest on a home equity loan used to purchase or improve rental properties is deductible on Schedule E as a business expense, but not on Schedule A for your primary residence.

Money is...important, but it's also a way to make a positive difference in people's lives. 

Folks this is meant as a beneficial post and not about good or bad positions.  

I hired a litigator to review my position, and they concluded that we had a very strong case.

I spent 5 years buying 5 primaries and 5 rentals.

Inflation will push up rents over time, so at some point you will be cash flow positive.
