How It Works

Property maintenance costs are ongoing expenses every landlord must budget for. The 1% rule (1% of property value annually) is the most common guideline, but older and larger properties typically cost more.

The Formula

1% Rule = Property Value * 0.01; Sqft Rule = Square Footage * $1.50; Age Adjustment = +0.25% per decade over 10 years

Variables

  • 1% Rule — Annual maintenance at 1% of property value
  • Sqft Rule — Estimate based on $1-2 per square foot annually
  • Age Adj — Additional 0.25% of value per decade for homes over 10 years old

Worked Example

$350,000 home, 20 years old, 1,500 sqft: 1% rule = $3,500. Sqft rule = $2,250. Age-adjusted = $350,000 * 1.25% = $4,375. Recommended = $4,375/year ($365/month).

Practical Tips

  • Budget 1-2% of property value annually for maintenance reserves.
  • Older homes (30+ years) can require 2-3% of value annually.
  • Separate capital expenses (roof, HVAC) from routine maintenance in your budget.
  • Build a maintenance reserve fund before buying — don't start at zero.
  • Regular preventive maintenance is cheaper than emergency repairs.

Frequently Asked Questions

What is the 1% rule for maintenance?

Budget 1% of your property's value per year for maintenance. A $300,000 property = $3,000/year. This covers routine repairs, not major capital expenses.

What are the biggest maintenance costs?

Roof ($8-15K), HVAC ($5-10K), plumbing ($2-5K), and appliances ($500-2K each). These are capital expenses that occur every 10-25 years.

Can I deduct maintenance costs?

Yes — repairs and maintenance on rental properties are fully deductible in the year incurred. Improvements must be depreciated over time.

How does property age affect costs?

Newer homes (<10 years) may only need 0.5% of value. Homes 20-30 years old typically need 1-1.5%. Homes 40+ years may need 2%+.

What should I include in maintenance budget?

Routine: landscaping, pest control, cleaning, minor repairs. Capital: roof, HVAC, water heater, appliances, flooring, painting. Don't forget vacancy turnover costs.
