Municipalities Struggling to Keep Pace with Rapidly Rising Home Prices

(By Joe Schulz, Wisconsin Public Radio) Municipalities are struggling to keep pace with rapidly rising home prices, creating the largest gap between local property tax assessments and market values in recent years.

According to Joe Schulz with Wisconsin Public Radio, that’s according to a new report by the Wisconsin Policy Forum. The report says the gap between assessed and market values has spawned concerns about the fairness of Wisconsin’s property tax system.

When property reassessments do occur, the report says many will see "huge increases" in their assessed property values. But that doesn’t necessarily mean they’ll see the same increase in property taxes.

Over 800 Wisconsin municipalities have assessed values for the properties in their borders that are lower than 80 percent of their market value, according to the report. That’s the largest gap since at least 2011.

Ari Brown, a researcher for Wisconsin Policy Forum and the report’s author, said the main cause for that gap is "the hottest housing market in recent memory" over the last few years. "When property values are rising so quickly, it is hard for local assessors to keep up with that," he said. "There's just a lack of supply and housing right now to meet demand."

On top of trying to catch up to a booming housing market, revaluations can be a major expense for local governments, on top of other necessary costs like infrastructure investment, Brown said.

A revaluation is a program undertaken by a municipality to appraise all property within its boundary to its full and fair value. For example, a full revaluation for the city of Rhinelander, which has a population of roughly 7,800, would cost nearly $160,000, according to the report.

Staffing constraints also make it difficult for local governments to catch up on assessments, said Jerry Deschane, executive director of the League of Wisconsin Municipalities.

"Municipalities are trying to do their job, they're trying to catch up," he said. "But there's a limited number of human beings out there, called state-certified assessors, and there are not enough of them to go around."

The report said Wisconsin is one of only eight states which assesses property values entirely at municipal level, as most dedicate that responsibility to counties. From a budgetary perspective, Brown said making Wisconsin counties responsible for revaluations could ensure they’re done more frequently. But that may not solve the entire problem.

"You still need the staff to do that," Brown said. "A full revaluation requires individual assessors going into every single home in the community to basically run a checklist of what is in this home? What makes up the value of this home? Even if there was the budget, you still don't have to worry about getting the staffing to do all of that."

If every property in a community were equally under-assessed, it wouldn’t necessarily lead to an unfair distribution of property taxes, the report said. But the gap between market and assessed values may mean that some neighborhoods or types of properties are more likely to be paying more or less than their fair share, the report added.
