A new survey focusing on affordable housing providers and insurance costs and availability has found that rental businesses are facing much higher premiums—nearly one in every three policies had rate increases of 25% or more. The survey, conducted by ndp analytics and commissioned by the National Leased Housing Association (NLHA), aligns with other recent research released earlier this year by the National Multifamily Housing Council, which found that 26% of property insurance costs have increased over the past year.
