Property Expenses
How to track expenses against a property.
Add an expense
On the property, go to the Expenses tab, then click Add Expense.

Fill in the date, category (Maintenance, Repair, Utilities, Insurance, Cleaning, Mortgage, Tax, or Other), a description, and the amount. Payment method, vendor, reference number, account code, and receipt key are all optional — typing a new vendor name offers to add it to your vendor list on the fly.

Click Add Expense. It shows up immediately in the month's expense list, and the running total updates at the top.

Use the month navigation and category/type filters to review past expenses, and Export CSV to pull the data out.
Expense Rules
The Expense Rules sub-tab lets you set up recurring expenses (e.g. a monthly mortgage payment) so you don't have to log them by hand every period.
