Pretty straightforward trophy
First order of business is to get yourself a vehicle. If you played the intro you should’ve gotten a free one from Simeon. If you skipped it, run into traffic and grab one you like. Bring it to a Los Santos Customs and fit a tracker onto it.
Now, at rank 5, you have the ability to purchase some real estate by going to the Dynasty8RealEstate website on your in-game phone. The cheapest apartment is 0112 Rockford Dr Apt 13 for a small price of $80,000. This apartment already includes a garage so there’s no need to buy one separately.
Now be like Roman Bellic and enjoy the American dream!
