I'd be talking to at least 10 national lenders from biggerpockets and have your land appraised. you better have permits in hand, entitlements. complete, etc. sounds like it's too early to be talking about financing. 

It sounds scary, but it is setup that way as a consumer protection. 

To elaborate, there are statutes and administrative regulations (found in Fannie/Freddie guidelines) that provide a laundry list of exemptions from them calling the loan due to a transfer in title (EG divorce, death, inheritance, asset protection/estate planning).It sounds like they misunderstood your question as you asking that you wanted to transfer the loan, which you've obviously clarified on here. 

It sounds like they're just playing around and ignoring you.

It sounds like they were the real deal but all of a sudden got "buyer's remorse". 

And that sounds like a good reason to get the contract notarized and recorded.

At this point the exchange account has enough cash so the exchanger can complete their exchange. 

WOW that sounds criminal on Ms Elie's account..

Regardless it sounds like you've set yourself up to do well in either case. 

That’s another task in itself if I was to continue since I’m completely new to this.
