Properties are available to purchase in Grand Theft Auto V to either generate income, or to provide storage for vehicles. Purchasing businesses will also unlock the property management side missions for some establishments. A minimum of five properties must be purchased by the characters in order to satisfy 100% completion.
Most properties will be available to be purchased after completing Trevor's mission Nervous Ron.
Vanilla Unicorn will allow all the characters to touch the strippers while having a private dance. Trevor will also have private dances and drinks free of charge. This is the only obtainable business property that also doubles as a safehouse (for Trevor). It also the only business property that has an accessible interior to it's main building, as all the nightclubs cannot be accessed, nor can the leisure center at the golf course. The theatres can be somewhat accessed, but only two of the three can be accessed to watch movies.
The Airport Hangars will grant Michael and Franklin clearance to enter the airport's tarmac, thus won't get a wanted level from getting in. Note, however, that each character must purchase a hangar in order to get in safely (so if Franklin buys a hangar, Michael will still get a wanted level until he buys one). Many high-end aircraft spawn and can be stolen and parked in the hangar.
All of the DLC vehicles will be placed in each of the 3 main character's garages
Franklin has the option to buy most properties as him only, with 4 only available to him. Michael is second with 3. Trevor is the lowest with two, however he is given Sandy Shores Airfield and Vanilla Unicorn without having to buy them.
As of update 1.16, all marina, hangar and helipad properties are automatically equipped from the beginning of the game. If the player is connected to the Rockstar Games Social Club, then they will have the garage for free as well, meaning no vehicle storage facilities need to be bought.
With the free add ons, as Trevor, the player saves a total of $105,000 and as Michael and Franklin, the player will save $1,903,450.
