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

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

Thanks in advance, IrisHi Iris,I ended up transferring ownership to the LLC and didn't have any issues.

Hi Kin,Transferring your share of the property to your brother may have tax implications, including gift tax if the transfer is considered a gift.

They are not transferable.These are just the facts.In the case of selling a business you're not transferring the account, you're transferring ownership of the business. 

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? 

You have three choices...transfer the property and keep the loan in tact hoping they won't trigger due on sale, refinance into a loan that allows it, or simply leave things as they are. 

If one is transferring property title from personal name, a Grant/Warranty Deed would be drafted/recorded to transfer title. 

Would it be possible for my wife to transfer the house/deed into her name (or buy the house, etc.) so we can take a loan against it to help pay for the memory care?

If so, there are no transfer taxes due.
