When your client buys a home for 200K that was sold 2 years ago for 250K and is assessed at 240K are they calling the tax assessor out. Most governing authorities are taxing your home on the "market value". In my market, a home's tax assessed value was usually about10-20% less than what it would sell for. In todays market, homes are selling for 10-20% less than what the tax assessed value. Which means to me and my clients that the governmental authority needs to come out and adjust your assessed value because how can they assess you on a value that is more than what you actually paid(real market value). Every new homeowner should be doing this. It could reduce their taxes by 10-20%. Good luck!!!!!!
