We have purchased a new house and plan to list our current house for sale in the spring. Because of the location it might take 2-4 years to sell. This house will be quite profitable. A neighbor told me there is a (new?) rule about only having the profit on the sale tax free if you live in it 3 of the last 5 years. Does it make sense to sell it for less than we would like before that 3 years is up to avoid the taxes on the profits? Are there other considerations?
