a future idea on how to become wealthy ???

is it possible for a nurse working in southern california to eventually gain enough money to have something like a 300k car.

this is more of a talk as im young but just genuinely wondering if its possible to pick up 12 hour night shifts monday-friday for 90 days with a tax exempt use that money on a large loan and buy a property ( maybe out of state) that can pay me back atleast 12k a month and cost maybe a 1mil. drop 10k a month into the property to pay itself and pocket 2k a month to pay off the tax exempt at the end of the year. coming next year now i profit 2k a month and stay there or use that money to repeat the process to buy another property with similar numbers. so by year 2 im down 2million (ish) but im pocketing 4k a month for the next 8 years ( still dumping 20k out of the 24k total revenue until debt ) and by about 8 and a half years both propertys are payed off and now im profiting 24k a month. from that point i either put that money into living how i want fairly comfortably or i put it back into more propetys while also working as a nurse just with normal shifts again. the reason i brought up a car is because a 300k car with no downpayment is about 5k a month over a 60 month term. would something like this work ?

now i know i didnt take into consideration interest rates and everything but this is just a very broad idea assuming i eventually get a pay of 100 an hour since i know thats genuinely possible in socal.

if u have other ideas on how i could get a 300k car thats different from this please let me know.
