Mello-Roos enabled "Community Facilities Districts" (CFDs) to be established by local government agencies as a means of obtaining community funding. Counties, cities, special districts, joint powers authority, and schools districts use these financing districts to pay for public works and some public services.
It is a bond indebtedness against all properties in the district.
A Mello-Roos District is an area where a special property tax on real estate, in addition to the normal property tax, is imposed on those real property owners within a Community Facilities District. These districts seek public financing through the sale of bonds for the purpose of financing public improvements and services.
According to Fannie:
Appraisal Requirements for Properties Located in Special Assessment Districts
The appraisal requirements for properties located in special assessment districts must report any special assessments that affect the property, and
note in the appraisal report if the special assessment district is experiencing financial difficulty and that the difficulty has an effect on the value or marketability of the subject property.
To ensure that the reaction of the market to the potential liabilities that may arise within a financially troubled special assessment district is reflected in his or her analysis, the appraiser must consider current and expired listings or properties for sale within the district and any pending contract sales and recent closed sales within the district.
There may be some instances in which the financial difficulty of a special assessment district is so severe that its actual effect on the value and marketability of a property is not measurable because there is no comparable market data available to enable the appraiser to arrive at a reliable opinion of market value. When this is the case, a mortgage secured by a property in that district will not be eligible for delivery to Fannie Mae until such time that an active market develops that will enable the appraiser to demonstrate the value and marketability of the subject property.
During the meltdown of 2008 with so many homes that went into foreclosure, the property taxes and the CFD taxes were delinquent. The CFDs reassessed the paying property owners to make up for the delinquency to pay bond holders. It does make a difference on market value and the marketability of a home.
