I would like to retire in 10 years and am considering selling the house which could produce about $1.4M after realtor fees, then use that to buy ~3ish rental properties cash in an 1031 exchange so I minimize the tax exposure and start producing monthly cashflow that can provide the basis for a retirement in 10 years.

This is for the unit my wife and I will be living in) their prices are set at $323 or $403 per window, and we quoted the better windows for the parts of the house with constant sun exposure at just under $8000.
