When to sell my my home when getting one built in another state

[Paul Johnson]

I plan on selling my home in Cleveland, Oh and build a house in Florida not sure when to start the Sale or Build process. I have already purchased the land cash and have about 150k in equity in my home I'm selling and plan to use that money for the new house I also can use the 89k that i purchased the 7.5 acres with. I also want septic, solar and a pool so now I'm not sure when to bring these subcontractors into the process. I found the builder i want to use and is vetting them now. I own 27 doors following Bigger Pockets suggestions over the years retired 2 years ago. any advice would be gladly appreciated. Thanks in advance
