One side vacant with a long term up to date tenant on the other side, rent on the occupied was $100 over what the mortgage payment would have been, plus the property qualified for conventional.

Conventional Mortgage What was the outcome?

If you are working with a conventional lender, refinancing/ HELOC follows the same general process as a new loan (underwriting)...there are some exceptions to this, but it depends on the lender/loan product, and situation...

I'd do 3-5% conventional.

That's been my experience whether it's FHA, conventional or even DSCR.  

@Haresh PatelIt really depends on what you're looking for; conventional or DSCR/Asset based lending. 

@Joshua Zdunich by "traditional" loan I think you mean a "Fannie/Freddie" type of loan - or a "Conventional, Conforming" loan as they are sometimes called.

All conventional financing... some houses in my name and some in my partners.

You won't find many if any FHA, VA, Conventional, USDA, etc... programs which all typically yield lower rates.
