So take a bad deal now with the promise of maybe refinancing in 10 years. If that even ever happens again. And most of the interests are being paid upfront.
Hell, most people will not even want to live in the same place in 10 years.
Honestly this sounds like yet another argument from a realtor to push prices irrationally to all time high.
It's the same thing. The only difference is in taxes.
If you refinance your monthly rate goes down. And you get a tax break.
