Property ROI FAQ
How does the Property ROI calculator handle offline time?
Offline hours earn 25% of the displayed hourly income, based on the checked Property interface.
What does the +10% option mean?
It models the permanent group-and-like Property income bonus visible in the interface.
Are the preset purchase prices permanent?
No. They are dated samples. Newsstand Front was recorded after one was already owned, so its $590 price is specifically labelled account-state data.
Does payback include theft, Bank fees, or spending?
No. It divides purchase price by modelled Property income and clearly excludes other cash flows.
