Rent, costs, yield and value for one property.
Open a property and choose Finance to see the money for that one property: what it earns, what it costs and what it is worth.

The pills — This month, Year to date, 12 months, All time — set what the figures cover. Net cashflow is income minus expenses for that period. Every payment and cost that makes up the headline is listed further down the tab under Transactions, so no number is one you cannot trace.
Yield & value is the part only on this tab: gross yield, and the value you entered. Yield needs that value. Without it we leave yield blank rather than guess.
Compare against your area gives you a starting figure.
Rent status shows what is due and what has been paid. Import / export brings a spreadsheet in or takes your figures out.
Tools holds Add transaction, Statement of accounts, Mortgage settings, the Connect Xero or FreeAgent entry and Connect bank. Property details is on the Overview tab.
Everything recorded here rolls into the portfolio Finance page and the tax estimate as you go. There is no overnight job.
The button beside Rent status says who owns the property. It reads Held personally, the name of your company, or Managed for and the owner's name. Select it to open How this property is held.
The menu shows the answer. It does not change it. From the top it lists:

To change the answer, select Change who owns it. The Who owns this property? window opens with three choices: Me, One of my companies and For someone else. Each is explained in Jointly owned property. The window is also on Property details, under Ownership, and in Settings, on the Company tab. All three change the same answer.
The answer changes how the tax is worked out. A property you manage for its owner is described in Managing a property for its owner. Putting a company name on tenancy paperwork is in Putting your company name on it.
