The wun pay property tax?
Either he will get a magic pass or some other dim org will foot the bill.
Maybe he will rent the Secret Service the guest house like Bill & Hillary did in NY. Charge the SS enough rent and have them pay the mortgage. BJ charged the SS $10K/month rent. That covered their mortgage payment on the house in Westchester County, NY.
Although, the mortgage on this shack will be a little more.
$14 million for Obama’s house is quite a lot higher than Bill & Hill’ place.
