RSA 80:42 — Transfer of Tax Lien; Sale of Property Taken in Default of Redemption. –

I. No transfer of any tax lien upon real estate acquired by a town or city at a tax collector's sale for nonpayment of taxes thereon shall be made to any person by the municipality during the 2-year period allowed for redemption, nor shall title to any real estate taken by a town or city in default of redemption from a tax sale be conveyed to any person unless the town, by majority vote at the annual meeting, or city council by vote, shall authorize the selectmen or the mayor to transfer such lien or to convey such property by deed.
II. If the selectmen or mayor are so authorized to convey such property by deed, either a public auction shall be held, or the property may be sold by advertised sealed bids. The selectmen or mayor shall have the power to establish a minimum amount for which the property is to be sold and the terms and conditions of the sale.
III. The selectmen may, by a specific article in the town warrant, or the mayor, by ordinance, may be authorized to dispose of a lien or tax deeded property in a manner than otherwise provided in this section, as justice may require.
IV. Such authority to transfer or to sell shall continue in effect for one year from the date of the town meeting or action by the city council provided, however, that the authority to transfer tax liens, or to sell real estate acquired in default of redemption, or to vary the manner of such sale or transfer as justice may require, may be granted for an indefinite period, in which case the warrant article or vote granting such authority shall use the words "indefinitely, until rescinded" or similar language.
V. For purposes of this section, the authority to dispose of the property "as justice may require" shall include the power of the selectmen or mayor to convey the property to a former owner, or to a third party for benefit of a former owner, upon such reasonable terms as may be agreed to in writing, including the authority of the municipality to retain a mortgage interest in the property, or to re-impose its tax lien, contingent upon an agreed payment schedule, which need not necessarily reflect any prior redemption amount. Any such agreement shall be recorded in the registry of deeds. This paragraph shall not be construed to obligate any municipality to make any such conveyance or agreement.
