Not a pro here but just a guess:
I didn't really check the prices for some of the things but have a reaaallly rough estimation from seeing some prices of construction machines, hardware etc &more and I'd assume he would have gone through atleast 100-300 thousand USD already which would leave him at around 36,250,000 so he could go on for awhile but looking at the growing costs and the scale of things and how much time has passed, he could very easily spend it all within a year or two o_o"...
Isn't the money just going to run out? This is just too outrageous!!! He keeps buying things like his money won't run out!!!
