Market demand

Market demand is the supply of prospective tenants for each room market. It is different from Room evaluation: demand determines who is available to lease, while evaluation helps determine which rooms they choose and whether existing tenants remain satisfied.

Prospect pools and leasing

Residential, office and commercial tenants use separate prospect pools. Condos and apartments share the residential pool. A completed lease or sale uses one prospect, regardless of the number of residents or workers it brings into the tower. An unsuccessful search leaves that prospect available for a later search.

Permanent tenants search during the map's daytime hours: normally 06:00 to before 20:00. Searches take place once per daytime hour, at a randomly selected minute between :20 and :50. Not every waiting prospect searches every hour. Eligible rooms compete with one another and with alternatives outside your tower, so even a suitable vacant room is not guaranteed a tenant immediately.

Prospects replenish hourly, including overnight. New games begin with a full pool; normally it can hold three days of baseline arrivals. The pool cannot grow without limit, and arrivals beyond its capacity are lost. Building more rooms does not create prospects. Evicting tenants or losing them does not refund prospects.

An empty pool means nobody is currently waiting to move in. It does not by itself make existing tenants leave. Use Room evaluation to investigate their satisfaction.

Stars and arrival rates

Higher stars increase the baseline rate of new prospects. These are the default rates before map and difficulty adjustments:

Stars	Residential prospects/day	Office prospects/day	Commercial prospects/day
0	6	6	0.4
1	9	9	0.6
2	12	12	1
3	15	15	1.6
4	18	18	2.4
5	24	24	3.6

Map settings and difficulty affect the baseline. Market conditions, reputation, advertising and events can change the rate actually arriving. Fractional prospects accumulate, but a lease needs one whole prospect. Earning another star expands the pool's capacity and future inflow; it does not instantly fill the extra capacity.

Advertising

Only one advertising campaign can be active in each sector at a time. For permanent tenants, campaigns increase prospect replenishment rather than instantly filling rooms or adding a lump sum to the pool. Advertising does not improve existing tenants' evaluation results.

The small, medium and large campaigns add 15, 30 and 50 percentage points to the tenant arrival adjustment for 2, 3 and 5 days respectively. Check for suitable vacancies and room in the prospect pool before spending: a full pool wastes additional arrivals, and prospects still have to choose your rooms.

Hotels and visitors

Hotel bookings and daytime commercial visitors use separate markets and arrival schedules. They do not consume residential, office or commercial tenant prospects. Hotel advertising improves the tower's attraction to travelers rather than creating more regional travelers; competing hotels still receive a share. Events and disasters can temporarily change demand or visitor attraction.

Commercial tenants need customer traffic after moving in. Improve visitor attraction, access and service quality as well as the supply of prospective businesses.

Worked examples

Illustrative default prospect pool: at zero stars, residential arrivals have a baseline of six prospects per day. Three baseline days give a pool capacity of 18 prospects before map and difficulty changes. A Condo sale consumes one prospect, even if it brings four residents. Adding 100 vacancies does not create 100 prospects. Maps such as Nostalgia can change the baseline, so use the actual pool shown in your game.

Conceptual tenant flow: hourly arrivals → capped prospect pool → daytime room search → chosen lease or sale. A successful lease consumes one prospect; an unsuccessful search leaves it in the pool.

Illustrative store visitor feedback: two occupied base stores initially contribute 2 × 17.5 = 35 target visitor trips per day before wider market adjustments. Suppose the last three completed days contain 30 assessed store visitor trips and 21 succeed: 21 ÷ 30 = 70% satisfaction. That lies in the 60–85% steady band, so it does not trigger growth or decline in the tower's store-feedback target. The target is not a guaranteed count of visitors or customers. See Store visitor demand for the full rules.

Practical tips

• Expand in stages rather than expecting a large block of identical rooms to fill at once.
• If vacancies remain, check daytime leasing hours, whole prospects available, room eligibility and evaluation.
• A displayed daily leasing chance is an estimate based on current prospects and competing rooms, not a promise of a lease.
• Keep serving existing tenants well during a downturn; a slow arrival rate and poor tenant satisfaction are different problems.
