Return on investment calculations for rental properties tend to focus on purchase price, rent income, and financing costs. Maintenance rarely gets the same level of attention during underwriting, and that gap tends to show up painfully once a property is under ownership.
The standard rule of thumb is to budget between one and two percent of a property’s value annually for maintenance. On a $400,000 Philadelphia property, that is $4,000 to $8,000 per year before any emergency repairs or capital improvements. For older construction, which describes a significant portion of Philadelphia’s rental housing stock, that figure often runs higher. Ignoring it in an ROI model does not make it go away. It just makes the actual returns look worse than projected.
Deferred maintenance compounds the problem. A $200 gutter repair left unaddressed becomes a $1,500 fascia replacement. A slow drain ignored long enough becomes a plumbing call with water damage attached to it. Each of those escalations eats directly into net operating income and, by extension, the return the property is supposed to generate.
Predictable maintenance costs are also easier to finance and plan around than emergency ones. A property owner who sets aside a consistent maintenance budget each month is in a fundamentally different position than one who absorbs unplanned repair costs from cash flow. The numbers might average out to something similar over time, but the stability and predictability of the former makes for a healthier investment posture.
Maintenance is not a drag on ROI. Unplanned, reactive maintenance is. The distinction matters more than most owners realize until they are already in the middle of it.
