How to Calculate Cap Rate for Memphis Rental Properties

Cap rate is the number Memphis investors quote in every deal conversation. A 10% cap on a Whitehaven property. A 6% cap in Cordova. The problem is that most of these numbers are calculated wrong, and the ones that are calculated correctly are often applied to decisions cap rate was not designed to answer.

Here is the correct formula, what the Memphis numbers actually look like when you run them against real operating costs, and where cap rate stops being useful.

The formula, stated correctly

Cap rate equals net operating income (NOI) divided by property value. NOI is gross rent minus all operating expenses, before any debt service. The mortgage payment does not go into the NOI calculation. This is the most common error: investors subtract the mortgage and call the result NOI. That produces a financing-dependent number that shifts every time interest rates move. Cap rate is designed to measure the property independent of how you finance it.

Operating expenses that belong in the NOI calculation: property taxes, insurance, property management fees, a vacancy allowance, maintenance reserves, capital expenditure reserves, and turnover costs. Every recurring cost of ownership except the mortgage and income taxes.

On a Memphis single-family rental generating $1,200 per month, the operating expense picture using Shelby County benchmarks looks like this:

• Property taxes: $175/month (approximately $2,100 per year on a $150,000 property)
• Landlord insurance: $115/month
• Property management at 10% of collected rent: $120/month
• Vacancy allowance at 7%: $84/month
• Maintenance reserves at 1% of property value: $125/month
• Capital expenditure reserves: $150/month
• Turnover costs averaged over expected tenancy: $40/month
• Total operating expenses: $809/month

NOI on this property: ($1,200 minus $809) multiplied by 12 equals $4,692 per year. On a $150,000 purchase price: cap rate equals $4,692 divided by $150,000, which is 3.1%.

That 3.1% is not a rounding error. It is what a fully-expensed cap rate looks like on a standard Memphis single-family rental at this price point. Most investors quoting 8% or 10% on this same property are calculating gross yield, which is annual rent divided by purchase price, not cap rate.

Gross yield vs. cap rate: why the distinction matters

Gross yield is simple: ($1,200 times 12) divided by $150,000 equals 9.6%. It tells you the raw rent-to-price ratio and is useful for quick deal screening. It is not cap rate.

Cap rate requires subtracting real operating expenses from gross rent before dividing by the purchase price. The gap between gross yield and cap rate is the operating expense load, which runs between 40% and 60% of gross rents on most Memphis single-family rentals depending on the neighborhood, property age, and management intensity.

When two Memphis investors compare "cap rates" but one used gross yield and the other used fully-expensed NOI, they are not comparing the same number. In a market where investors routinely quote gross yield as cap rate, every published benchmark is suspect until you know which calculation was used.

What Memphis cap rates look like by area

Using the fully-expensed methodology, Memphis neighborhoods produce different cap rates that reflect actual operating costs, not just rent-to-price ratios.

Whitehaven, Frayser, and Hickory Hill: entry prices of $70,000 to $110,000 with rents of $850 to $1,050 per month produce gross yields of 10% to 14%. After full operating expenses that include above-average vacancy (10% to 12% in these neighborhoods versus 7% metro average), higher maintenance frequency on older housing stock, and standard management costs, fully-expensed cap rates land at 5% to 7%. The yield is real. The expense load is also real, and it is heavier here than in suburban markets.

Cordova and suburban Shelby County: prices of $180,000 to $280,000 with rents of $1,200 to $1,400 per month produce gross yields of 6% to 8%. Vacancy below 5%, tenant stays averaging 2.5 to 3.5 years, and newer construction reduce the operating burden relative to gross rent. Fully-expensed cap rates in this range: 3.5% to 5%. These properties do not deliver strong current yield. The investment case rests on predictable cash flow over a long hold, low operational friction, and historical appreciation that has tracked above the metro average.

Midtown and East Memphis: prices of $225,000 and up in Midtown, $280,000 and up in East Memphis. Gross yields of 4.8% to 6%. Fully-expensed cap rates of 3% to 4%. Below-4% vacancy, minimal tenant turnover, and a high-earning tenant profile reduce certain costs, but purchase prices are high enough that the cap rate calculation produces a number that looks unremarkable on paper. These markets are total-return plays, not cap-rate plays.

A detailed breakdown of each area with specific price ranges, vacancy data, and the operational trade-offs that national ranking sites leave out is in the Memphis neighborhood investor guide.

Cap rate vs. cash-on-cash return

Cap rate ignores financing. Cash-on-cash return (CoC) measures annual pre-tax cash flow as a percentage of total cash invested. At 3% mortgage rates, cap rate and CoC told a similar story. At 7%, they diverge sharply, and that divergence is the most important piece of analysis on any Memphis deal right now.

On the $150,000 Memphis property: $30,000 down payment, $120,000 financed at 7% for 30 years, mortgage payment of $798 per month. Annual cash flow after all operating expenses and the mortgage payment: ($1,200 minus $798 minus $809) times 12 equals negative $4,884 per year. Cash invested: $30,000 down payment plus approximately $3,500 in closing costs, totaling $33,500. Cash-on-cash return: negative $4,884 divided by $33,500, which is negative 14.6%.

The cap rate says 3.1%. The CoC return says negative 14.6%. Both numbers are correct because they measure different things. Cap rate measures the property as an unlevered asset. CoC measures whether the deal works with your specific financing at today's rates.

When the mortgage rate exceeds the cap rate, financing pulls the CoC return below zero. This is not unique to Memphis. It describes every residential rental market in the country where mortgage rates outran cap rate compression since 2022. The Memphis value neighborhoods at 5% to 7% fully-expensed cap rates are closer to break-even than the premium neighborhoods, which is why value-area properties are where the transaction volume has held up most among financed buyers.

What cap rate cannot answer

Cap rate tells you the yield on an asset if you paid all cash today. It does not tell you what happens when the roof fails at year 9, or whether the neighborhood supports rent growth over the next decade, or whether the property attracts a tenant who stays for 30 months or 8 months.

A 6% cap rate in Whitehaven and a 5% cap rate in Cordova are not interchangeable risk profiles. The Whitehaven property at 6% carries above-average operating demands: higher vacancy risk, more management intensity on older construction, and a tenant population under more financial pressure. The Cordova property at 5% typically represents newer construction, longer tenant stays, and lower day-to-day operational friction. Net returns over a 7-year hold on both properties depend more on operational execution and neighborhood trajectory than on the entry cap rate.

Cap rate is the right first filter for comparing deals. It is not the complete analysis. The full cash flow model accounts for all the variables cap rate skips, and the output is different enough from the cap rate number to change which deals actually make sense.
