How Property Value is Determined

When a property is assessed, someone from the county tax assessor’s office will come out to physically inspect your home to determine its worth. When are property assessments done? You pay property tax annually, but home value assessments may only occur every five to seven years or when you sell the home.

What is the assessed value of my home? They will usually determine the assessed value of a home through a formula based on the total replacement cost, the market value, and the rental value of your home.

To calculate the replacement cost of your home, the assessor will inspect the building materials and consider your maintenance costs. If you are making income from your home, they will also consider this when determining the value.

How is the value of property damage determined? To find the market value of your home, the assessor will compare your home to similar properties in the area that have recently sold.  Aside from the physical condition of your home, the market value of your home will turn heavily on real estate market trends.

Assessed Value Property Tax

Your property’s value is assessed to find your required annual property taxes. Your determined tax rate is found through the state’s “assessment rate” and “mill levy.” Tax law requires that these rates remain consistent during the tax period, usually one year.

Once your property value is found, the county or state will apply the assessment rate. This rate varies widely among districts. For example, if the value of your home is $300,000, and your state’s assessment rate is 40%, then your taxable property value is $120,000.

The state property tax percentage, or “mill levy,” is then applied to the tax-assessed value of your home to determine your annual property taxes. This means that if the state tax percentage is 2%, and your taxable property value is $120,000, your annual property taxes will be $2,400.

How often do they assess property taxes? Depending on where you live, anywhere between one and seven years. You pay property taxes every year, but how often property taxes are reassessed will depend on your state and county laws.
