Its a catch-22 Ed, great time to buy... not so great time to sell. I do 1031 Tax Exchange deals all the time, and in fact..., I am about to do another one this coming month. - Not a lot of details in your question, but if it is your family home and occupied by family you should not have to do a 1031. Just rent it or sell it.
The 1031 issue comes into play when you have to sell a "non-owner" occupied property that you have not occupied in the past two years (some States may differ). The burden of Capitol Gains can be anywhere from 10-15% and sometimes even higher. You REALLY must consult with a Tax Exchange specialist, no kidding. That will be your first thing to do today! - I use a professional company that is tied into one of our local Title companies... they are great and give lots of free adivce.
Its just my 2 cents worth.., and I hope this has helped a bit.
