Section 52. Cities and towns may make regulations for the possession, management and sale of land purchased or taken for taxes, not inconsistent with law, regulations promulgated by the department of revenue or the right of redemption. The treasurer of any city or town holding 1 or more tax titles may assign and transfer such tax title or titles, individually or bundled, to the highest bidder after a public auction, after having given 14 days’ notice of the time and place of such public auction by publication, which shall conform to the requirements of section 40, and having posted such notice in 2 or more convenient and public places in said city or town, provided that the sum so paid for such assignment is not less than the amount necessary for redemption, and may execute and deliver on behalf of the city or town any instrument necessary therefor. The treasurer shall send notice of the intended assignment to the owner of record of each parcel at his last known address not less than 10 days prior to the assignment, but failure to receive such notice shall not affect the validity of the assignment. The instrument of assignment shall be in a form approved by the commissioner and shall be recorded within 60 days from its date and if so recorded shall be prima facie evidence of all facts essential to its validity. The instrument of assignment shall, for each parcel assigned thereunder, state the amount for which the tax title on the parcel could have been redeemed on the date of the assignment, separately stating for each parcel the principal amount and the total interest accrued until the date of assignment. The principal amount shall be the sum of the amounts for which the parcel was taken and amounts subsequently certified under section 61. Except as hereinafter otherwise provided, all provisions of law applicable in cases where the original purchaser at a tax sale is another than the city or town shall thereafter apply in the case of such an assignment, as if the assignee had been a purchaser for the original sum at the original sale or at a sale made at the time of the taking and had paid to the city or town the subsequent taxes and charges included in the sum paid for the assignment. Any extension of the time within which foreclosure proceedings may not be instituted granted by a city or town treasurer prior to assignment shall be binding upon the assignee.
