1031 - Substantial Improvement before selling

[Mike Rash]

I have a 1 FAMILY RENTAL property that I have been renting out for 2 years.

My cost basis for the property is 500k.

I would like to do substantial improvement to the property by building addition

and increasing square footage by about 200%. The improvements

would cost around 400k. Then, I plan to sell it for about 1,400,000.

With proceeds, I plan to purchase another rental property(s).

Is there way I can structure this so that it qualifies for 1031 exchange?
