Under M.G.L. c. 175 §193P, how many days' advance written notice must a MA insurer give before non-renewing a MA homeowners policy at expiration?

Why this is the answer

M.G.L. c. 175 §193P requires every policy insuring a dwelling or its contents against fire to provide that the insurer will give the insured written notice of its intent not to renew at least 45 days before the policy expires. The notice must state the specific reasons so the insured has time to seek replacement coverage in the voluntary market or through the MA FAIR Plan / MPIUA.
