When considering the costs of homeownership, it’s sometimes easy to forget about property tax. Home buyers focus a lot of attention on their prospective mortgage payment and the potential cost of any remodels and renovations but often forget to think about how much taxes will run them each year. This is a mistake. Take, for example, new research from ATTOM Data Solutions. Their recent tax analysis found that the average property tax on a single family home last year was $3,399, a 3 percent increase from 2016. That’s nearly $300 a month. But property taxes can differ from one place to the next. As evidence, states like Hawaii, Alabama, Colorado, Tennessee, and West Virginia were found to have lower than average effective property tax rates. They can also vary from city to city. That’s why it’s a good idea to look into how much homeowners pay in property taxes in the areas where you’d most like to buy a home. It may not sway your decision on where you buy, but it will give you a more accurate assessment of how much it’ll cost to buy a house in a particular city.
