Raynham, Mass., Code of Bylaws ch 230 § 230-10

A. The Rent Board, in regulating rents, may make such individual or general adjustments, either upward or downward, as may be necessary to assure that rents for mobile home park sites are established at levels which yield to owners a fair net operating income for such units and to tenants reasonable site rents based on current economic conditions. Application for site rent changes may be made by both licensees and tenant(s) of mobile home parks in the Town of Raynham. Any application for change in site rents made by tenants may not be used as a premise for increasing rents or other charges. B. "Fair net operating income" shall be that income which will yield a return, after all reasonable operating expenses, on the rental value of the property in question equal to the average consumer price index rate increases over the last successive twelve-month period immediately prior to the date of application for increase or such other rates of return as the Rent Board, on the basis of evidence presented before it, deems more appropriate to the circumstances of the case. C. The "fair market value" of the property shall be the assessed valuation of the property or such other valuation as the Rent Board, on the basis of evidence presented before it, deems more appropriate to the circumstances of the case. D. The Rent Board may establish further standards and rules consistent with the foregoing.
