One of the most common questions new landlords ask is how much they should set aside for maintenance and repairs. Unfortunately, it’s also one of the questions with the most conflicting advice.
You’ll hear rules like “budget 5% of rent,” “always plan for 10%,” or the vague but technically correct answer: it depends. That confusion often leads landlords to under-budget early and learn expensive lessons later.
The reality is this: maintenance costs don’t disappear just because you didn’t plan for them. Older buildings, in particular, will collect their share eventually.
The Truth About Maintenance Percentages
There is no single percentage that works for every rental property, but there are realistic ranges based on age and condition.
Newer or Recently Renovated Properties
If a property has newer systems, updated plumbing and electrical, and no deferred maintenance, landlords may get by with 5–7% of gross rent in the short term. This assumes inspections were thorough and prior owners didn’t cut corners. According to data published by Zillow and Apartments.com, newer rentals consistently report lower first-year maintenance costs due to reduced system failures and warranty coverage.
Even then, this range works best as a temporary baseline, not a long-term guarantee.
Average-Age Properties (10–30 Years Old)
For most rentals, 8–12% of gross rent is far more realistic. Systems are aging, parts are harder to replace, and small issues tend to stack up over time. This range helps cover recurring repairs without constant cash flow stress. Based on investor guidance from sources like BiggerPockets and industry maintenance benchmarks, this range reflects the most common long-term averages.
Older Buildings
For older properties with original plumbing, aging roofs, or outdated electrical, 12–15% or more is not excessive—it’s responsible. One major system failure can easily wipe out multiple years of conservative budgeting. According to reports from Redfin and long-term rental performance studies, deferred maintenance is one of the top drivers of unexpected operating losses in older buildings.
Older buildings don’t break more often; they just break more expensively.
Do Maintenance Costs Ever Stabilize?
This is where many landlords get tripped up.
Costs don’t truly stabilize. What does happen is predictability.
The first one to two years of ownership are usually the most painful. This is when deferred maintenance surfaces and surprises show up. After that period, expenses become easier to anticipate, but they don’t necessarily decrease. This pattern aligns with long-term ownership data discussed in real estate investment analyses across platforms like BiggerPockets and AppFolio market reports.
Landlords who say their costs “stabilized” usually mean they stopped being shocked—not that they stopped spending.
Repairs That Surprise New Landlords the Most
Cosmetic issues are easy to plan for. Hidden systems are not. The most common budget busters include:
Sewer line and drainage failures
Electrical panel upgrades or rewiring
Plumbing leaks inside walls or under slabs
Roof and flashing failures
Code-required upgrades triggered by inspections or tenant complaints
These repairs don’t announce themselves politely, and they’re rarely cheap. According to property management case studies published by AppFolio and regional housing authorities, system-related failures account for the majority of high-cost emergency repairs.

The Right Way to Think About Maintenance
The biggest mindset shift successful landlords make is treating maintenance as a non-negotiable operating expense, not an occasional inconvenience.
Buildings age. Systems fail. Materials wear out. Whether you budget for it or not, the cost shows up eventually.
Budgeting conservatively doesn’t mean you’ll always spend that money—but it ensures you won’t be forced into bad decisions when something breaks.
Final Thoughts
If you budget optimistically and you’re wrong, cash flow pain is immediate. If you budget conservatively and don’t need it, you’ve protected yourself.
Maintenance isn’t about perfection. It’s about resilience.
Planning ahead is how landlords avoid learning this lesson the hard way.
