But the person seemed bent on me wire transferring within 3 days, or the deal will no longer be valid.

This appears to be a 'transfer tax' instead of an income tax. 

Up until November, actively licensed VRD (Vacation Rental Dwellings) could transfer one time to the new owner.

Please note that contrary to common belief a lender can NOT prohibit a transfer, they could only declare such transfer a item that allows them to accelerate the note.Up until now, very few notes have been “called” due when title has transferred.  

With today's high interest rates, it usually doesn't make sense.

I have a 2.5% interest rate on the balance of the mortgage. 

A relative who does long-distance real estate investing told me that I have to sign the final loan document and the transfer of ownership document in person.

Were the transfers from the tenant credit card or ACH transactions. 

I'm constantly juggling the rates for my Airbnb listings based on what my competitors are charging. 

Quote from @Dinesh Nair: I am a Canadian investor with a US corporate entity- we closed on our first property and now working to find financing through a lender… however rates keep changing all the time.. is there a site to track rates ?
