Owned property functions as a personal fast-travel point usable directly from the map. Open the map and select the orange house icon.
Prerequisites
Own (single player) or rent (multiplayer) at least one plot.
Or have a parked motorhome on the map.
Multiplayer rule
In multiplayer, "you can teleport to any owned property or parked motorhome regardless of who owns it, preventing players from being locked out of the fast travel system". This is the official design choice — the network is shared.
Server fees
Community servers commonly charge a small fee per teleport — ASEAN Motor Club sets it at 100 coins per use, for example. Check your server's rules.
Etiquette
Building a public parking spot on your plot lets other players spawn a vehicle after fast-travelling in. It's considered good multiplayer manners on community servers.
