@Marko Bukva Transferring the deed of your wife’s grandmother’s house from the trust to your name has significant tax implications.

@James Thompson Transferring property from your in-laws to you can be done through a gift, sale, or trust transfer, each with different tax implications.

You would then simply transfer it back to the named borrower.If you wanted to decrease the DOS issue, you can transfer to a revocable trust with the entity as beneficiary. 

Both my aunt and my mother’s husband have agreed to remove their names from the title, transferring sole ownership to my mother.

My goal is to transfer both the deed and the mortgage to an LLC.

Both my aunt and my mother’s husband have expressed their willingness to remove their names from the title, granting sole ownership to my mother.My mother is interested in transferring ownership of the property to me and allowing me to live there.

However, I do have a lender that can conduct an entity transfer with a commercial loan from 2 units and up.

This would allow us to come to the table with less funds out of pocket on the front end when starting construction.Is the best way to complete the transfer of ownership through a traditional sale registered with the county? 

Fannie/Freddie (Conventional) loans aren't just about rate and transfer taxes. 

@Jorge Liang Closing the loan under your personal name saves about $1,200 in lender points, but transferring the title to an LLC later comes with costs and risks.
