No tax due when you move in. But you will not get the 250,000/500,000 capital gain exemption when you sell it unless you live there for 5 years. This is longer than the normal 2 year rule for getting a home sale exemption from gains.
You should consult a CPA or tax attorney on this. Even if you live in it you will not be able to sell the property tax free.
Why? You were able to take a depreciation on your old property and then received a gain on it when you 1031 exchanged it. A 1031 only defers taxes not avoid it.
