As a bank officer, I underwrote residential and commercial mortgages.

They talk with successful investors of all kinds - buy and hold rentals, commercial, flippers, wholesalers - you'll get a great overview of the options across the REI landscape. 

Not all lenders are the same, they are more different than most people thinkTHAT lender may not do blanket loans, the but the vast majority of them do. you just need a simple commercial loan with 6 pieces of colatteral, nothing special.

Some investors purchased it about a year ago and are seeking to turn it into apartments and commercial space (Greer Mill Development).

I tried to find an alternative way to make money in real estate, and now am working with a broker for commercial properties. 

I work on the commercial side of lending, but I can provide contact info for the residential RE Manager, if you like.

Hi all, We have a commercial space available in a large building we're breaking ground on in the next month.

A road to access my sellers house had been there for 50+ years with no complaint by the land owners. 

If the LLC refinances it into commercial financing that you aren't personally liable for, different story. 

Your options are to find an alternative Commercial Lender who specializes in these types of transactions.
