Help! Mid-Atlantic Appraisal Consultants NJ

[Thien Luu]

Hey BiggerPockets,

I need advice because I received a letter from Mid-Atantic Appraisal Consultants INC. 

I purchased my parents 2 family home by assuming their mortgage last October.

The letter states I can be overpaying my 2018 property taxes by $$$ unless a tax appeal is filed before the deadline. 

The company states they work in conjunction with state certified appraisers and legal firms to successfully reduce real estate taxes for property owners in the Garden state.

The fee arrangement is handled on a contingency basis where fees are incurred only after my property taxes are reduced.

Does anyone use them before? 

Do they reduce your taxes and is this legit?

Thank you,

Thien
