Don’t know if the housing market is hot in Delaware but if it is, now is a good time to sell but the Motorhome market is hot also. Why did you sell the C if only going to RV for several months???
Are you going to move to a lower tax state or stay in Delaware with a smaller house? The current housing bubble and RV frenzy will bust but hard to say if it will be one year or two years. Selling your home now and using a motorhome for a couple years to buy low in the future might make sense.
Hard to give answers when there’s so many questions.
