The Maintenance Calendar That Keeps My Four Rentals From Exploding at Once

Let’s run the numbers.

Unscheduled repairs across four properties: Average $4,200–$6,500 per year in reactive costs, plus stress and emergency calls at bad times.

With my maintenance calendar: Around $2,100–$2,800. Fewer emergencies. Predictable budget. Better tenant retention.

This calendar is my single best system. It’s simple, shared, and actually used. Here is the full detailed version I rely on.

The Core Philosophy

Preventive > Reactive.

Schedule everything possible. Review quarterly. Adjust based on property age and tenant feedback.

I use a shared Google Sheet with tabs per property plus a master view. Color-coded. Recurring reminders.

Monthly Tasks (Every Property)

• Change HVAC filters (all units).

• Inspect and clean visible plumbing under sinks.

• Test smoke and CO detectors. Replace batteries as needed.

• Check exterior for issues (gutters, landscaping).

• Walk-through visual for obvious problems.

Time per property: 30–45 minutes.

Quarterly Tasks

• Deep clean exterior (power wash if needed, or schedule).

• Gutter cleaning.

• Pest inspection (I do visual, pro once a year).

• Appliance checks (fridge coils, dryer vent).

• Caulk and sealant touch-ups in wet areas.

Semi-Annual / Annual

• Professional HVAC tune-up (spring and fall).

• Roof/gutter inspection.

• Water heater flush and check.

• Full interior pest treatment if history.

• Smoke detector full replacement every 10 years.

Property-Specific Adjustments

Older properties get more frequent checks on plumbing and electrical. Newer ones focus on landscaping and appliances.

I have notes column for each: “Property 3 — watch foundation after heavy rain.”

How I Execute It

• First week of month: Block time for checks.

• Delegate what makes sense (lawn care to tenants or service).

• Log completion and any issues immediately.

• Budget reserve contribution based on upcoming big items.

Example: Water heaters are 8–12 years old on two properties. I’m planning replacements in next 18 months. Saving monthly.

Integration with Life

The calendar syncs with my personal one. No surprises during Chloe’s recital or Ethan’s games.

Otis even has vet appointments noted — because life doesn’t pause.

Results So Far

• Major emergency calls down 70%.

• Average tenant stay longer.

• Better cash flow predictability.

• Less panic.

This is unsexy work that pays the biggest dividends.

I review the whole thing every January with fresh eyes. Tweak frequencies.

It’s not perfect. Things still break. But far fewer “explosions.”

Build your own. Start simple. Add as you go.
