I’d take the house if it’s truly a $4M house, assuming that I can sell it for $4M. I would then sell it, pay the taxes, and invest the $1.9M. I can never see myself living in a 7k+ sq-ft house. I rather live in a small house w/ panoramic ocean view than a ginormous house w/out ocean view.
Do you have to pay the tax on day 1 or do you pay it at tax day? What happen if you don’t pay the tax right away? How much penalty do you incur?
