1031 for new construction?

[Sean H.]

I'm about to sell a property for 300k, my capital gains will probably be around 100-150k. I don't like to mess with rentals, so im trying to figure out if there's any way i can make a 1031 work in the flipping world. The lots i usually buy are 100-150k. 

If i understand a 1031 correctly, if i sell the house for 300, i have to put all of the 300 in the 1031. Is it possible to put 150k towards the lot, and 150 towards the construction?
