Unfortunately there is a rate adjustment adjustment between 75% and 80% ltv on almost any product.

I wasn't sure if the loan product matters.

When they hear Wholesaler they think in the wholesalers who supply retail stores with Products.  

Yes there are products that can up to 80% LTV for DSCR with 6 months reserves.

In addition being able to do your own searchs and one thing out west here that was very productive for us/me was just going through the big Plat maps ( the actual mylar / paper ones in the day) We could find shadow plats.

Are there lenders that will lend on the product at competitive rates that are similar to current 30 yr sfh amortization?

I would find all of the places in my area that posted apartment listings and literally put my listing there and pay for any advertising product that was available to push my listing to the front. 

I believe up to close to 40% down with a 720 or greater credit score on a conventional loan product could give you the best interest rate.
