I’m curious how different investors calculate their maintenance reserves. A simple percentage of rental income seems straightforward, but I imagine the appropriate amount can vary significantly depending on the property's age, condition, location, and major systems.
For example, would you use a fixed percentage of annual rent, a per-property estimate, or a combination of both?
Also, do you keep separate reserves for major capital expenses such as a roof, HVAC, or plumbing, or include everything in one maintenance reserve?
Interested to hear what has worked for investors with actual rental-property experience.

Amna, I’d separate maintenance from capital expenditure completely because they’re different risks.
Maintenance is recurring noise: plumbing calls, appliances, turnovers, minor electrical, landscaping, small repairs.
CapEx is scheduled mortality: roof, HVAC, water heater, sewer line, exterior, major plumbing/electrical.
A percentage of rent is fine as a rough screen, but it’s a weak underwriting method because rent has almost nothing to do with how old your roof is.
For CapEx, I'd build a component schedule:
Roof replacement cost ÷ remaining useful life HVAC replacement cost ÷ remaining useful life Water heater Exterior/paint Windows Plumbing/sewer Major appliances Anything specific to that building
Add those annualized numbers together and that becomes the property's real CapEx reserve.
Then maintain a separate operating reserve for maintenance, vacancy and unexpected events.
The number I care about most isn’t “5% or 8% of rent.”
It’s:
What expensive thing can fail next, when is it likely to fail, and how much cash will I need when it does?
A 30-year-old property with a new roof, new HVAC and updated plumbing can deserve a smaller reserve than a 12-year-old property with every original system approaching the end of its life.
The age of the building is less important than the age of the components.
That distinction keeps a property that looks great on paper from suddenly becoming “negative cash flow” because the underwriting pretended a $12,000 HVAC replacement was an unpredictable event.

That's a really good point. I agree that separating routine maintenance from CapEx gives a much more realistic picture of a property's actual cash flow.
I especially like the idea of looking at each major component individually and considering its remaining useful life instead of simply applying a fixed percentage of rent. Roof, HVAC, plumbing, exterior, and other major systems can all have very different replacement timelines and costs.
This is also why I think looking at the complete property numbers is important when evaluating an investment. A property can look profitable based on current income and expenses, but upcoming major replacements can significantly change the actual returns.
The point about asking what could fail next, when it might happen, and how much it could cost is a very practical way to approach property analysis. Thanks for sharing this perspective!

@Halenah Eva, one thing I’ve seen with buyers is that the reserve number gets much easier to estimate when you really dig into the property before closing instead of starting with a flat percentage.
I like to look at the inspection along with any repair history, permits, warranties, seller disclosures, and records for the major systems if they are available. If the roof was replaced three years ago and the HVAC is new, that tells a very different story than a property where no one can tell you when anything was last replaced. I’ve seen buyers budget for repairs based mainly on age, then find out after closing that one system had already been patched several times and was much closer to failing than they expected.
I’d be glad to stay connected, @Halenah Eva. I think the best reserve number is the one tied to what you actually know about that specific property, not just a percentage that happens to work on paper.
