At game start you are assigned a house that you first spawn in. You own this house. You are able to purchase other houses and use them as Fast Travel points, as well as sell houses or rent them out for passive income.
To buy/sell houses you must be inside and close to the center of a house that is allowed to be purchased. Not all houses are allowed to be purchased. When in a valid house and near the center the "Real Estate" menu option will be active.
You cannot own zero houses. The game will not allow you to sell your last remaining house. A house that is currently set as your home also cannot be sold until you set another building as home.
A bed inside a house you own carries a Sleep action. Using it moves the world clock forward by eight in-game hours. See Sleep for the full rules on where and when sleep works.
Neither the sale price nor the rent of a building is a flat figure. Each building type has a base price and a base rent, and both are then scaled by the population and the stability of the nearest town. The same kind of house is therefore worth more in a large, settled town than in a small unsettled one, and a building's value moves as that town's situation changes.
When you rent out a property, you'll receive passive income from tenants. Rent is settled once per in-game day, at midnight: whoever rents a building pays, and whoever owns it is paid. A renter who cannot afford the payment stops renting. Here are some important details about the rental system:
There are soft limits on how many properties you can own. If you reach the limit, you'll be prevented from placing more properties, but there are no other restrictions or penalties.
A warehouse is a building with its own storage. You buy or rent it the same way as a house, from the same Real Estate menu.
A warehouse standing inside a base is different. Nobody can buy or rent it. It belongs to the base instead, and opens to whichever faction holds the base, and to nobody else, whatever its ownership record once said.
Access to a bought warehouse depends on how you hold it. An unowned warehouse opens to nobody. A private warehouse opens only to its owner. A public warehouse opens to everybody. A rented warehouse opens only to the renter.
An officer can rent a warehouse for the resistance instead of for themselves. A warehouse rented that way opens to everybody.
See Storage for what a warehouse can hold and how to move goods in and out of it.
The resistance can also build a warehouse, rather than buy or rent one. Building one costs money and all four construction resources. See Resources for how a construction site gathers those resources.
A built warehouse can stand at a base the resistance holds, or inside a town the resistance controls. A warehouse is the only building whose build list reaches into a town at all. A town the occupying faction still holds refuses it, and so does a village.
Once it stands, a built warehouse works exactly like a bought one: it appears on the map, carries an ownership record, and holds the same items and resources.
