Updated 2026 · Based on median market data for Decatur, IL
Home values in Decatur, IL have appreciated at 2.1% per year. Appreciation is modest at 2.1%, meaning total returns will be driven primarily by cash flow rather than equity gains. This is actually preferred by many investors who want predictable, income-based returns rather than speculative price appreciation.
If Decatur continues appreciating at 2.1% annually, the current median of $120,000 would reach approximately $133,140 in 5 years — an equity gain of $13,140 on a property purchased at the median. With a 20% down payment of $24,000, that represents a 55% return on invested equity from appreciation alone. Combined with 5 years of NOI totaling approximately $46,075, the projected total return is $59,215 — a 247% cumulative return on the initial investment. That breaks down to roughly 49% per year on your cash invested. Cash flow is the dominant return component, contributing 78% of total returns — a more conservative and predictable return profile.
Population growth in Decatur is minimal at 0.2%. Appreciation here is more likely driven by regional economic factors, inflation, and housing stock constraints rather than population-driven demand. Higher-than-average local incomes ($62,333) support continued price growth as more residents can afford to bid up properties and qualify for larger mortgages.
Slow growth of 0.2% means Decatur is vulnerable to economic shocks. A major employer leaving, a natural disaster, or a regional recession could tip growth negative and pressure values. The $120,000 price point provides some downside protection, as affordable markets historically experience smaller percentage declines during corrections. Interest rate changes also matter: a 2-point rate increase reduces buyer purchasing power by roughly 20%, which directly impacts resale values. Always stress-test your investment against a 15-20% value decline scenario.
The BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat) is highly viable in Decatur. The low median price of $120,000 means distressed properties can be acquired for $78,000-$90,000, rehabbed for $24,000, and stabilized at an after-repair value near $138,000. If you can refinance at 75% of ARV ($103,500), you recover most or all of your initial investment and retain a cash-flowing rental with strong equity. With modest 2.1% appreciation, the BRRRR math must work at today's values — do not count on future appreciation to bail out a thin deal.
Over a 10-year hold on a $120,000 Decatur rental purchased with 20% down ($24,000), wealth accumulates from three sources. First, appreciation: at 2.1% annually, the property reaches $147,720, producing $27,720 in equity gain. Second, cash flow: after debt service of approximately $7,661/yr, net cash flow totals roughly $15,540 over 10 years (before any rent increases). Third, loan paydown: your tenants' rent payments reduce the mortgage principal by approximately $12,480 over 10 years. Total wealth created: approximately $55,740 on an initial investment of $24,000. That is a 232% total return, or roughly 13% annualized. These returns illustrate how rental property builds wealth through multiple simultaneous channels. These projections assume constant appreciation and do not account for rent growth, which would improve cash flow over time.
Smart investors evaluate both cash flow AND appreciation. In Decatur, the 7.68% cap rate provides strong ongoing cash flow, while 2.1% annual appreciation adds an equity component. The strong cash flow here means your returns are mostly realized as income rather than paper equity — a more conservative and predictable return profile that provides income you can reinvest or live on. The key question for Decatur is your time horizon: even a 3-year hold produces positive total returns thanks to strong cash flow.
