Rolling spec house profits into next house. How?

[Skye Parker]

This is probably a bonehead question but I've been talking to some spec home builders and they are paying taxes on all profit from a spec home at personal capital gains tax rate. A heavy hit on a big project. I'm just curious - it seems like a big housing developer like Landsea homes for instance would take all proceeds from a development sale and count it as assets on the company balance sheet, then deploy that money on the next project. Isn't that what big companies do? Like a car maker for instance. They don't count profits on each car as income then pay taxes on that. They just collect that money on their balance sheet so they can use it to build more factories or reinvest in the company. Isn't that how it works? If that is how it works - Can that business structure be applied to a developer? What business structure is required if this is possible?
