Times staffAfter months of declines, the mortgage delinquency rate in the Tampa Bay area is climbing again largely due to September’s Hurricane Irma. According to CoreLogic, nearly 9 percent of bay area borrowers were at least 30 days late on their payments in October compared to 6.4 percent a year earlier. While the national impact of hurricanes Irma and Harvey is waning, "the local impact remains,’’ said Frank Nothaft, CoreLogic’s chief economist. "Some Florida markets continue to see increases in early-stage delinquency transition rates in October, reaching 5 percent, on average, in Miami, Orlando, Tampa, Naples and Cape Coral.’’ One reason for the increase is that many lenders allowed borrowers affected by Irma to skip a payment. On a positive note, the percentages of Tampa Bay borrowers "severely delinquent" on their mortgages — 90 or more days late — dropped to 2.9 percent in October from 3.7 percent a year earlier while those with homes in some stage of foreclosure declined from 1.5 percent to 0.9 percent.
