We are presently finalizing plans to purchase Rushmore. This unit will be our fulltime residence. I am not yet retired but preparing. In the government "first time home buyer" legislation enacted earlier this year, there was a little known "longterm owner incentive". If you lived in a stick house consecutively for five years in the last 8 years, you are elgible for a max $6500 tax credit when you purchase new home. Current regs say mobile home, condo, apartment, or regular house. Has anyone in the rv community applied for this credit??? I have asked IRS and awaiting response. Enjoy the forum and am looking forward to our new rushmore.
