I went through the process all the way to equalization board last September and they told me they would email me the decision never herd from them i had done a assessment by Jo Ann Apostle that said that because of the easement the sellers agent lied about the property was supposed to have and did not that if the septic tank that was installed in the mid 70s went bad there was no access to the back yard to replace it that the house would be condemned and only worth the price of the land went to the city of Brighton the said i was 5' shout of frontage to annex and couldn't get a sewer tap I believe that during appraisal or title work someone could have warned me of this but now I know I have to divulge this so cannot sell property and is only worth about 69,000.00.
