It was the case for Kenneth Rankel, 58, and his husband when they received a notice from their mortgage lender last week that they had a shortage in escrow as a result of rising insurance costs, and therefore their monthly payment would be increasing by about $323 a month. Some years there aren’t much changes, but other years, homeowners can receive notices of a shortage in escrow, or a notice that there aren’t enough funds in the account to cover that amount due, because of an unplanned increase in insurance or taxes. The second property tax bill after the new resident has owned the property for a full year would reflect the current owner’s exemptions, and often, those savings may be lower than the previous owner’s,” noted the Palm Beach County Property Appraiser’s office.
