How to manage multiple apartments without losing your mind?

Where does the chaos come from?

Most landlords start with a spreadsheet and good intentions. The problems begin when there are more than two apartments, each with a different tenant, payment date, and set of utilities to reconcile.

Three biggest traps

• No single source of truth — invoices in email, contracts in Word, rent in Excel. During an inspection or a tenant query you waste hours searching.
• Forgotten deadlines — chimney inspection, expiring lease, deposit return date. Every missed deadline is a potential legal or financial problem.
• No payment history — when a tenant claims they paid in March and you don't remember — who's right?
