4 SFH Build Tax Strategy

[Account Closed]

I am building 4 single family homes and expect a very nice payout. Interested in how investors/cpas would structure this to maximize after tax return.

I bought the property for 800k. The seller didn't know what they had, and I can divide into 4 lots. I am building 4 SFHs with a build cost of 1.5million. I estimate each home will sell for 825k/SFH.

After carrying costs and expenses, I expect to net ~600k pre tax. Now the question, can I make this a long term capital gain and then move into one of the properties? 

If I can do this legally, my thought is to wait until a year has passed and then move into the last property after the other properties have sold and realize the gain (20% capital gains tax). Then live in the house for 2 years to shelter another 500k (married) in taxes when selling.

Thoughts or suggestions? Thanks!
