b. If a lienholder responds in writing to the landlord concerning a security interest in any manufactured or mobile home, and the lienholder indicates an intent to remove the property from the premises, or from the place of safekeeping, or to pay rent as a condition of leaving the property on the premises, but fails to remove the property or make rental payments within the time specified in the notice or within 15 days after the written response, whichever is later, then the landlord may proceed as if the lienholder had not responded.
c. If no response is received from a tenant or lienholder within the time period provided under section 3 of P.L.1999, c.340 (C. 2A:18-74), then the tenant’s property shall be conclusively presumed to be abandoned.
