The town’s tax rate was set this week, at $10.94 per $1,000 for residential properties and $11.60 for commercial properties. To the owner of an average-priced home of $300,000, it will mean a yearly increase of $252 on the property tax bill. Residential values on single-family homes have dropped by 11 percent over the last two years, according to Assessor-Appraiser Barbara Erickson. During that same time, two-family houses dropped 13 percent and three-family homes dropped 16 percent. Values on multi- family properties with four or more units also dropped in the two- year period, going down 10 percent. Condominium values were the only place that increases were seen, rising by about 3 percent over the last two years, Erickson said. Tax bills are expected to go out in mid-October.
