What This Data Tells Us About Renting vs Owning in Cass County

Primary driver

Income supports the median purchase price

Median household income is $68,125, putting the home-price-to-income ratio at 1.4x. Property taxes consume 2.9% of median income; use those two burdens separately rather than treating the mortgage payment as the whole ownership cost.

Decision signal 2

The tax rate is a national headwind

Cass County's 2.02% effective rate is among the highest of 3,135 tracked counties: only about 97% pay more. Treat that recurring tax line separately from principal and interest.

Decision signal 3

Buying compares well inside the state

Using the assumptions above, Cass County ranks 16 of 102 Illinois counties for buy-vs-rent value (rank 1 = the best relative deal for buying). It sits ahead of 86 other Illinois counties on this measure.

Decision signal 4

The monthly comparison favours owning

The median home value in Cass County, Illinois is $97,100 with a median annual property tax of $1,958, an effective rate of 2.02%. At 20% down on a 6.5% 30-year mortgage, the all-in monthly ownership cost comes to $682, under the $916/mo HUD prices a 2-bedroom rental at. Owning is about $234/mo cheaper before maintenance, HOA fees, or closing costs.

Decision signal 5

HUD moved the rent benchmark up

HUD raised its 2-bedroom Fair Market Rent for Cass County from $870/mo in FY2025 to $916/mo in FY2026: it increased by $46/mo (+5.3%). A rising rent benchmark widens the gap in favour of owning over time, because the mortgage share of the ownership cost below is fixed at origination while the rent it is compared against reprices every year.

Methodology & disclaimer

This calculator is for informational purposes only and is not tax, legal, or financial advice. Property tax figures come from the U.S. Census Bureau ACS 5-Year Estimates and rent figures come from HUD Fair Market Rents; both describe area medians, not individual transactions. Insurance is estimated at 0.35% of home value annually and closing costs, maintenance, HOA, and PMI are not included. Consult a licensed mortgage, tax, or real-estate professional before making a buy-or-rent decision based on these numbers.

Who actually pays it here

Even with the loan gone, the largest group of owners here still owes $3,000 or more every year. That is a permanent monthly obligation of a few hundred dollars, and it is why "paid off" understates the real cost of holding property in this county.

Households earning $50,000 to $75,000 file the largest share of these write-offs, an ordinary middle-income profile.

Bill bands are Census ACS counts of owner-occupied homes without a mortgage. Income brackets are IRS Statistics of Income county data for tax year 2022, counted over FILERS reporting real-estate taxes on Schedule A, which is a smaller group than homeowners: most filers take the standard deduction.
