Termination and Eviction in New Hampshire
N.H. Rev. Stat. Ann. §§ 540:1-a, 540:2, 540:3 states different rules apply depending on whether the property is “restricted” (most residential property) or “nonrestricted” (single-family houses, if the owner of such a house does not own more than 3 single-family houses at any one time; rental units in an owner-occupied building containing a total of 4 dwelling units or fewer; and single-family houses acquired by banks or other mortgagees through foreclosure). (See N.H. Rev. Stat. § 540:1-a.)
