Curious what a cap rate really tells you about an Evanston property? If you are comparing small multifamily buildings or student-oriented rentals, it can feel like a maze of numbers and jargon. You want a clear way to size up value and risk before you commit. This guide keeps it simple and local so you can interpret cap rates with confidence and use them alongside the right checks. Let’s dive in.
Cap rate basics
A cap rate is a quick way to estimate return from an income property based on today’s numbers. The formula is simple: Cap rate = Net Operating Income (NOI) ÷ Purchase Price. It is an unlevered snapshot, which means it does not include loan payments.
NOI is the property’s income after vacancy and operating expenses. It includes rent and other income, then subtracts expenses like property taxes, insurance, repairs, management fees, and any owner-paid utilities. It does not include mortgage payments, income taxes, or long-term capital replacements unless you treat them as an operating line item.
You use cap rates to compare risk and pricing across properties and to estimate value from an expected NOI. Lower cap rates usually signal lower perceived risk or stronger growth expectations. Higher cap rates often reflect more risk, operational complexity, or higher local costs.
What cap rates show and miss
Cap rates are helpful, but they are not a full investment model. Here is what they do well and where they fall short:
- What they show:
- A quick comparison of value and risk across similar properties.
- An implied price for a given NOI, or an implied return at the current price.
- What they miss:
- Financing terms and leverage effects.
- Future rent growth and tenant credit risk.
- Income taxes and near-term vacancy swings.
- Major capital expenditures that may be needed soon.
Use cap rate as your first filter, then build out cash-on-cash returns and IRR to capture financing and multi-year performance.
Evanston factors that move cap rates
Evanston sits within the broader Chicago metro and has distinct drivers that affect buyer demand, pricing, and cap-rate expectations:
- Proximity to Chicago and transit. The CTA Purple Line and multiple Metra stops give strong commuter access. Properties close to transit often trade at tighter cap rates because of convenience and demand.
- Northwestern University. Student, faculty, and staff housing needs create steady rental demand. Student-focused assets can have different seasonality and turnover, which affects underwriting and pricing.
- Diverse submarkets. Downtown Evanston, Central Street, Howard Street corridors, and residential pockets vary in rents, vacancy, and buyer profiles. Expect cap-rate differences by block and building type.
- Demographics and income. Evanston’s household income and education profile tends to support stable demand for quality rentals.
- Local rules and zoning. City ordinances, permitting, and policy discussions around rental housing can influence operating costs and redevelopment potential.
- Property taxes. Cook County assessments and local levies are a meaningful expense line. Tax levels and appeals history can shift realistic NOI and required returns.
- Supply pipeline. New multifamily or purpose-built student housing near campus can influence rent growth and vacancy expectations.
In practice, well-located properties close to Northwestern and transit, or in the downtown core, often command lower cap rates than assets on peripheral blocks. Higher taxes and operating costs tend to push cap rates higher if income does not keep pace. Broader conditions, like rising interest rates or a weaker regional job market, can push cap rates up across the metro.
Calculate cap rate step by step
Follow these steps to keep your underwriting consistent:
- Estimate effective gross income. Start with scheduled rent, subtract a market vacancy allowance, and add other income like parking or laundry.
- Subtract operating expenses. Include property taxes, insurance, owner-paid utilities, routine maintenance, management, legal or advertising, and reserves for replacement if you treat them as an operating line.
- Arrive at NOI. This is income after vacancy and operating costs.
- Divide NOI by the purchase price. The result is the cap rate.
Label your assumptions clearly, especially vacancy, management fees, and reserves. Confirm whether the cap rate you see in marketing materials is based on current income, historicals, or pro forma.
Evanston 8‑unit example (hypothetical)
Consider an 8‑unit apartment building in Evanston. The numbers below are illustrative only:
- Potential gross rent: $20,000 per month, or $240,000 per year
- Vacancy allowance at 5%: $12,000
- Effective gross income: $228,000
- Operating expenses per year:
- Property taxes: $40,000
- Insurance: $4,000
- Owner-paid utilities: $6,000
- Maintenance: $12,000
- Property management at 6% of EGI: about $13,680
- Other: $4,320
- Total expenses: about $80,000
- NOI: $228,000 minus $80,000 = $148,000
- If the purchase price is $2,960,000, the cap rate is $148,000 ÷ $2,960,000 = 5.0%
A 5.0% cap means a 5% unlevered return based on current income. Whether that is attractive depends on asset quality, location, recent Evanston comps, your financing terms, and your rent growth expectations.
Interpret cap rate differences
- Lower cap rate. Market sees the asset as lower risk, highly desirable, or positioned for growth. Often applies to well-located, well-maintained buildings near transit or employment anchors.
- Higher cap rate. Market requires more yield due to condition, location, turnover risk, or higher operating costs like taxes.
- Interest rates matter. Investors compare cap rates to Treasury yields, mortgage rates, and lender spreads. When interest rates rise, buyers often demand higher cap rates unless income growth offsets the change.
Avoid comparing a student-focused building to a conventional asset without adjusting for seasonality, turnover, lease structure, and management intensity.
Due diligence checklist in Evanston
Use this local checklist to validate income, expenses, and risk:
- Income and leases
- Verify rent roll against bank statements and tax returns.
- Review lease terms, security deposits, responsibility for utilities, and lease expirations.
- Compare current rents to market rents using recent comps.
- Operating expenses
- Pull Cook County assessment history, current tax bill, and any appeals or exemptions.
- Confirm insurance, utilities, routine maintenance, management fees, and vendor contracts.
- Request documentation for recent capital projects, plus realistic reserves for near-term replacements.
- Property and compliance
- Confirm zoning, permitted uses, and any open code violations or permits with the City of Evanston.
- Order a building inspection and, for commercial assets as needed, a Phase I environmental review.
- Market positioning
- Compile recent Evanston and nearby suburb sales for similar asset types. Compare cap rates, price per unit, and price per square foot.
- Note proximity to transit and Northwestern, plus any local development that may affect supply.
- Financing and scenarios
- Model cash-on-cash returns across interest-rate cases.
- Check lender debt-service coverage and loan-to-value requirements.
Buyer mistakes to avoid
- Relying on seller pro forma without stress testing rents, vacancy, and expenses.
- Underestimating property taxes or ignoring likely reassessments that change NOI.
- Missing CapEx needs, like roofs, HVAC, windows, or plumbing.
- Using cap rate as the only metric instead of layering cash-on-cash and IRR.
- Treating all Evanston submarkets as one and skipping true apples-to-apples comps.
Seller tips to price with cap rates
- Present historical NOI clearly, and separate any pro forma assumptions. Explain rent growth, vacancy recovery, and expense changes.
- Improve operations before listing. Small upgrades or expense controls that boost NOI can support a tighter cap rate.
- Provide support. Offer third-party statements and recent comps that back your pricing and the implied cap rate.
Complementary metrics and tools
- Cash-on-cash return. Incorporates financing to show the return on your invested cash.
- Internal rate of return. Models total return over the hold period, including sale proceeds and rent growth.
- Gross rent multiplier. A quick screen based on gross rent. Useful for first-pass sorting, not for final decisions.
