The Atlanta apartment market, much like the national market, capped off its strong 2012 performance with a strong 2013. Whether or not you are experiencing the growth in your property, the Atlanta GA tax assessor sees these numbers and will use them as a part of projecting what your property's tax value should be. If you're performing at-market, a small tax increase could simply track the increased vale of your building. However, if you aren't doing the same as your neighbors, the Atlanta GA tax assessors could end up overvaluing your building and leaving you with an unreasonably high tax bill. The first step in determining if this is the case is to compare your property to the market as a whole.
