Some of the questions to ask might be

Is your home in a census tract with high median home values and larger or newer homes ?

Are your neighbors doing the same ?

Did you purchase property your home   within the past three years?

Is your property a smaller older property in areas where there has not been a dramatic run-up in property appreciation?

Property taxes come in a lump sum that comes twice a year. Other kinds of taxes are more hidden so you don’t feel the pain.

If you are curious about the current value of your home, contact a local Realtor who knows the market well, and who can provide you with adequate information to make your decision.
