@Chris Blackburn, while I can't speak to this specifically, there are a few red flags I see in your post.1: A Realtor has to be a member of the national association of realtors, an industry trade group primarily focused on your typical home buyer.  

I would look for a custodian who does not charge a fee based on your assets.I normally see the costs being A one time set-up fee along with an annual reoccuring fee.The thing you want when opening up an SDIRA is that the return that you will make with alternative investments will be greater than the fee that is charged to you for the SDIRA plus the return you would have likely gotten with a regular IRA.

However, this depends on your lender's specific loan terms, as some treat LLC transfers differently.

What are your thoughts on my specific scenario, and predicted refi rates in general?  

Happy to connect with you and talk about a specific strategy that fits your needs.

The concern as far as I could tell center around two specific areas (I’m not saying that any of this did happen, just that the posters reported it) .

Quote from @Ariel Rivas: I don't know your market specifically, but it's typically cheaper to purchase those items at Home Depot or Lowe's.

They've also enacted a bed tax specifically targeting short term rentals.

I don't particularly like FB marketplace, either...I just keep using it because it's worked better for me than the alternatives...
