I live in a somewhat run-down home, owned it for 7 years now, which I am remodeling. There are 2 points I’m fighting the assessor about. First is that they lowered my %good while I’ve owned the property twice, once from 75% to 50%, and 2nd from 50% to 40%. Although RMV was lowered, neither time was MAV lowered, yet when they deem I have improved the property back from 40% to 50% they adjust MAV up with an exception. THis seems criminal to boost MAV when the property is only bouncing back from devalued condition and back to an MAV level corresponding to the original 75% good. Can I win this fight.
The 2nd issue is the value they used for my remodel is way higher than my costs along with using 2X materials to estimate contractor cost (I did the work myself) Is this approach acceptable? It could possibly qualify my remodel as “minor construction” and avoid the exceptions.
This remodeling was started in 2005 and They have applied exceptions in 2007 and 2010 with more coming. Can the fight consider back to 2007?
