Taxable Value of home doubles after purchase. How to appeal?

[Edwin Rajkumar]

I bought my first property last year and I received a Notice of Assessment and Taxable Valuation letter about a month ago letting me know that the taxable value of my property is literally about to more than double this year. If this happens it's going to put me at a negative cash flow position.

I want to make an appeal but I dont know how to go about doing so or if I even have a case to make. Does anyone have experience with this? Is there an attorney or someone I should hire? Please let me know. I need to make an appeal by July 31st so it's a bit time sensitive.
Thank you for any insight.
