Is Duncan Affordable?

Is Duncan an affordable place to live? That's a valid question to ask when you're thinking about moving to a new city. After all, how much it costs to live somewhere can be a huge factor in your decision. Affordability can be broken down into 3 common categories. The cost of living index (we talked about it earlier), housing expenses and income levels all play a big role in figuring out if a place is affordable. For instance, in Duncan, the median home price is 34.6% lower than what most folks pay across the country, and monthly rent prices are 26.5% lower than the usual rates.

What Factors can Influence the Cost of Living in Duncan?

Transportation: When public transportation options are limited or non-existent, residents frequently resort to vehicle ownership, which can significantly contribute to the overall cost of living. Monthly financial obligations encompass fuel, insurance, regular maintenance and potentially lease or financing expenses. In Duncan, the transportation index is 1.7% lower than the national average.

Urbanization: Urban areas with a wealth of amenities and employment opportunities tend to come with a higher price tag for living. Why? Well, more people want to be there, which drives up home prices and rents. On the flip side, less densely populated rural areas or places where there's not as much demand usually mean fewer attractions, things to do and slower job growth. That often results in a lower cost of living.

Taxes: Areas with higher taxes, including sales taxes and income taxes, can contribute to a higher cost of living. Paying more tax for everyday household expenses like clothing and food will result in higher costs, as will paying a higher rate of income tax. The general sales tax rate in Duncan starts at 4.5% and the income tax rates start at 0.25%.
