Why Property Taxes and Insurance Require Careful Underwriting
Some multifamily expenses can be influenced directly by strong management. A new operator may negotiate vendor contracts, improve maintenance processes, reduce unnecessary spending, or create more efficient staffing.
Property taxes and insurance are different.
These expenses are largely influenced by forces outside the day to day control of the property management team, yet they can have a major effect on Net Operating Income.
For passive investors, that makes them particularly important underwriting assumptions to understand.
Property taxes are often one of the largest expenses at an apartment community. The challenge is that the taxes paid by the previous owner may not accurately represent what the new ownership group will pay after acquisition.
In some jurisdictions, a sale can trigger a reassessment of the property’s taxable value. A property that has been owned for many years may have a tax basis significantly below its new purchase price.
If an investment is underwritten using only the seller’s historical tax bill without accounting for a potential reassessment, future expenses could be understated.
This can have a meaningful impact.
Suppose a property’s annual taxes increase by $100,000 after acquisition. Unless revenue increases enough to compensate for that difference, NOI declines by the same amount.
Because apartment values are connected to NOI, the impact can extend beyond annual cash flow.
Experienced underwriting therefore attempts to estimate property taxes based on the rules of the specific jurisdiction rather than simply copying the previous owner’s expense history.
Insurance creates a different challenge.
Multifamily insurance costs are influenced by property location, construction type, age, claims history, coverage requirements, weather exposure, replacement costs, and the broader insurance market.
Properties in areas exposed to hurricanes, flooding, severe storms, or other natural hazards may face especially significant premiums and deductibles.
This is highly relevant in many Sun Belt markets.
A property can have strong population growth and attractive apartment demand while still facing increasing insurance expenses. Both sides of the equation need to be considered.
Insurance deductibles matter too.
A lower annual premium does not necessarily mean better coverage. A policy could carry substantial deductibles or exclusions that create additional financial exposure if an event occurs.
Passive investors are not expected to become insurance experts, but they can recognize that the premium is only one part of the risk.
Property taxes and insurance share another characteristic: they can be difficult to reduce through ordinary operational improvements.
If landscaping is expensive, an operator may rebid the contract. If utility consumption is unusually high, management may investigate leaks or install more efficient fixtures.
A property owner cannot simply negotiate local tax rates downward because the budget needs improvement.
Insurance markets can also change significantly from year to year, leaving owners with fewer coverage options or higher premiums despite good property operations.
For this reason, conservative underwriting should give these expenses meaningful attention.
Investors can look at whether projected taxes reflect a possible reassessment and whether insurance assumptions account for the property’s location and current coverage environment.
They can also consider how much room the investment has if these expenses exceed expectations.
Does the property have sufficient cash flow? Are reserves available? Is the investment already operating with a narrow margin?
Those questions help investors think beyond the base case projection.
This does not mean investors should avoid markets with higher insurance costs or property taxes. Different markets have different tradeoffs.
A market with higher expenses may also have stronger job growth, population trends, housing demand, or barriers to new construction.
The objective is not to eliminate every risk. It is to price and underwrite those risks realistically.
Property taxes and insurance may not be exciting parts of a multifamily investment presentation, but they frequently have more influence on performance than investors realize.
Understanding them helps passive investors recognize why disciplined underwriting requires far more than projecting future rents.
Sometimes protecting the investment starts with paying close attention to expenses that ownership cannot easily control.
