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
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.
