The market is too efficient to let that happen unless there is more to the story.

@Kendra Blueitt Usually, you'd have to go through a mobile home dealership to buy new mobile homes which are made and manufactured in a factory.

If you have any intent on renting a portion of your residence that you're moving into, part of your new home could be considered 1031 but only the portion that is rented.Depending on the amount of equity you hold in your current two properties, it may be more tax efficient to do some sort of HELOC or cash out refinance to acquire the new property you will move into.You should also note that there is no capital gain exclusion for selling the investment property (except a 1031 which is temporary) but selling your personal residence using section 121 automatically excludes $250k (500k if married) of capital gain.If those avenues are not possible, you may be stuck with the capital gain tax.
