Key takeaways

  • Capex is not optional — it's deferred guaranteed.
  • Reserve 5% of gross rent annually for capex.
  • Roof, HVAC, plumbing, and turn costs are the big four.
  • A capex schedule extends asset life and resale price.
  • Vendors should be vetted before urgency arrives.

Core concepts

Capex categories

Roof (20–25y), HVAC (12–15y), plumbing/electrical (30y+), turn costs (every tenancy).

Sinking fund

Dedicated reserve account funded monthly so capex never hits cash flow.

Preventive maintenance

Annual HVAC service, gutter clean, pest control prevents 60% of emergency calls.

Vendor stack

Plumber, electrician, HVAC, handyman, painter, landscaper — vetted, on file.

Step-by-step framework

  1. 1Inventory remaining life of roof, HVAC, water heater per property.
  2. 2Fund a sinking fund at 5% of gross rent.
  3. 3Schedule preventive maintenance annually.
  4. 4Maintain vendor list with after-hours contacts.
  5. 5Review capex plan every 3 years.

Common mistakes to avoid

  • Treating capex reserve as 'extra cash flow.'
  • Skipping preventive HVAC service.
  • Calling random vendors during emergencies.
  • Deferring small repairs into large ones.
