There’s no magical calendar date, but what really works is tying home checks to something that already happens every month. For many people, that’s the day salary comes in, or the day they pay bills or rent. On that same day, or the nearest weekend, do a quick house walkthrough.
You can treat it like a mini ritual: once a month, check smoke alarms, look for damp patches, test all taps and flushes, glance at the electrical panel, and inspect balconies and windows. It takes 20–30 minutes when you know what you’re looking for.
Some people like the first Saturday of each month; others pick the last Sunday. The actual date doesn’t matter. Consistency matters. If you already sit down on the 1st to sort finances, attach “house check” to that habit.
Over time, this regular mini-inspection means problems rarely surprise you. You notice the small crack before it becomes a big one, and the tiny leak before it destroys a wall.
