As can I, but the discount will be reflected in the borrower's closing cost. That, and there is a lot more legwork on the lender and borrower's end to get an underwriter to approve such a loan. Odd that your pushing a mod like you sell, or, live in one. You say "proven fact." I'd like to see the proof;backed by pictures, evidence, and some sort of repeatable provable analysis.
To make sure people dont think a Mod=Single Family home, here are the guidelines for Fannie/Freddie, the GSE's who's directives drive the US lending industry. Like it or not, they make the rules.

Read the bottom-you need to see Section H33.3e for Mods

Even if you don't know what your reading, its easy to see a loan for a Mod is much more difficult that a standard home. Consequently, your rates and fees will reflect that. And HAVE FUN taking a cash-out refinance for one!
