Your Rental Shows 8.6% Cash-on-Cash but Only 4.6% Return on Equity: When to Hold, Refi, or Sell and Redeploy

Why Your Original Cash-on-Cash Stops Telling the Truth

Picture a landlord who bought a rental six years ago with $52,000 out of pocket. The property now throws off $4,472 a year in cash flow, and she tells anyone who asks that it earns a "solid 8.6% cash-on-cash." She's right about the math. But the house has appreciated and the loan has been paid down, so she now has roughly $159,000 of net equity sitting in it, and that equity is earning less than 5% a year.

To see why, start with the fundamentals. Net operating income (NOI) is rent minus operating expenses (taxes, insurance, repairs, management, vacancy), before any mortgage payment. Cap rate is NOI divided by the property's value, which tells you what the asset earns unlevered. Cash-on-cash return is annual pre-tax cash flow (NOI minus debt service) divided by the total cash you invested, including down payment, closing costs, and any upfront rehab.

The problem is the denominator. Cash-on-cash measures your return on the cash you put in years ago, and that number never changes. Meanwhile, your real stake in the deal keeps growing as the property appreciates and tenants pay down your principal. A metric anchored to a six-year-old check will flatter almost any long-held rental.

Return on equity fixes this by asking what your money earns today. The formula is ROE = (annual cash flow + annual principal paydown) / net equity, where net equity = current value - loan balance - selling costs. Subtract selling costs (agent commissions, transfer taxes, closing fees) because equity you can't extract without paying them isn't fully yours. In our landlord's case, $4,472 of cash flow plus about $2,842 of principal paydown is $7,314 a year, and $7,314 / $159,000 works out to 4.6%.

That 4.6% is the number that matters for deciding what happens next. It's your opportunity cost: the return you're accepting by leaving $159,000 parked in this house instead of somewhere else. Cash-on-cash tells you whether the deal was good when you bought it. Return on equity tells you whether keeping it is still a good deal now.

Worked Example: Running Today's Numbers on a 6-Year-Old Rental

Take a single-family rental bought six years ago for $180,000. You put $45,000 down and paid $5,000 in closing costs, so you have $50,000 of your own cash in the deal. The $135,000 loan sits at 4% for 30 years, which works out to about $645 a month, or $7,734 a year in principal and interest.

Rent is now $1,850 a month, or $22,200 a year. After a 5% vacancy allowance ($1,110), effective gross income (EGI) is $21,090. Operating expenses look like this:

• Property taxes: $3,000
• Insurance: $1,500
• Maintenance (8% of rent): $1,776
• CapEx reserve (5% of rent): $1,110
• Management (8% of EGI): $1,687

That totals about $9,073, so net operating income (NOI) is $21,090 minus $9,073, or roughly $12,017. Subtract the $7,734 mortgage and annual cash flow lands near $4,283. Divide that by your original $50,000 and you get a cash-on-cash return of 8.6%. On paper, this is a solid rental.

Now value the property at today's price. Say comparable homes support $300,000, and the loan balance has dropped to about $119,600. If you sold, you would lose about 7% to commissions and closing costs, or $21,000. Your net equity is $300,000 minus $119,600 minus $21,000, which leaves about $159,400. That is the real capital this house is tying up, not the $50,000 you started with.

Measured against today's numbers, the picture changes fast. The cap rate on current value is $12,017 divided by $300,000, or 4.0%. Cash return on equity is $4,283 divided by $159,400, or 2.7%. Add the roughly $2,990 of principal you will pay down in year seven and total return on equity rises to $7,273 divided by $159,400, about 4.6%. That is barely more than a high-yield savings account, earned on a house that still needs tenants, repairs, and oversight.

Worked Example: Hold vs. Cash-Out Refi vs. Sell and Redeploy

Take the same $159K of equity and run it through three paths. Holding is the baseline. The property throws off about $7,300 a year in cash flow, so $7,300 / $159,000 = roughly 4.6% return on equity before appreciation. That is a safe return, but it trails what the same dollars could earn elsewhere.

A cash-out refi looks tempting until you run it. At 75% LTV on a $300K value, the new loan is $225K. At 7% over 30 years, that payment is about $1,497 a month, or $17,964 a year. Against $12,017 of NOI, cash flow drops to $12,017 - $17,964 = -$5,947 a year. You pull out roughly $84K (less closing costs), but you turn a performing rental into a monthly bill. When rates have climbed since your original loan, refi math often breaks exactly like this.

Selling and redeploying into a flip changes the picture. Say you net about $135K after selling costs and find a house with a $250K ARV needing $40K of rehab. Your MAO is ($250,000 x 0.70) - $40,000 = $135,000. Subtract roughly $20K in selling costs and $10K in buying and holding costs, and a $135K purchase projects $35K to $45K in profit over about six months. That is active work with real risk, but the return dwarfs 4.6%.

Selling into a new rental near a 7% cap is the quieter option. Put $135K down on a $270K property producing $18,900 NOI. A $135K loan at 7% costs about $898 a month, or $10,778 a year, leaving $8,122 in cash flow. That works out to about 6.0% cash-on-cash, a modest step up from the 4.6% you earn by holding.

The weak link in any comparison like this is the redeployment deal, because a guessed ARV or rehab figure can make selling look better or worse than it really is. FlipSmrt takes a candidate address and returns ARV from adjusted sold comps within 0.5 miles, line-item rehab priced for that county, MAO, and ROI in under 5 minutes. Run two or three real targets before you list the rental, and you can weigh holding against actual numbers instead of hopeful ones.

Nuances That Change the Answer: Taxes, Rates, Appreciation, and Effort

Gross equity is not what you get to redeploy. Say your rental would sell for $400,000 and you show $190,000 in equity. Selling costs around 7% take $28,000. If you have claimed $35,000 in depreciation, recapture taxed at up to 25% could cost about $8,750. Capital gains tax on the appreciation might take another $15,000. That leaves roughly $138,000 actually working in the next deal, which changes every return comparison you run.

A 1031 exchange can defer those taxes if you roll the proceeds into like-kind investment property within the strict identification and closing deadlines. That keeps the full $162,000 (after selling costs) in play instead of $138,000. The rules are technical, and the exchange is a poor fit for flips held as inventory, so talk to a CPA before you list. Treat any tax figure in your own model as an estimate until a professional confirms it.

Your mortgage rate also matters more than most spreadsheets admit. A 3.25% loan on $210,000 costs about $914 a month in principal and interest. Replacing that debt at 7% would run roughly $1,397. That cheap debt is a real asset you give up when you sell or refinance, so price it into the hold column instead of ignoring it.

Model appreciation and rent growth as separate lines, not as part of cash-on-cash. If rents in your area rise 3% a year, a $2,400 rent becomes about $2,700 within four years, which lifts cash flow without adding capital. Appreciation is useful upside, but it is a forecast, so test a flat-price scenario too. If the hold only wins when values climb, that is a bet, not a plan.

Finally, count your time and risk. A flip that targets a 20% return might eat 15 hours a week for six months and carries rehab overruns and resale risk. A stable rental might need two hours a month. Rule of thumb: compare after-tax redeployable equity against the hold, adjusted for the work each option demands.

Common Mistakes When Deciding to Hold or Sell a Rental

The biggest error is measuring cash-on-cash against the cash you invested years ago. If your rental produces $4,300 a year in cash flow on a $50,000 down payment, you see 8.6% and feel great. Against $93,500 of current net equity, that same cash flow is only 4.6%. Fix: divide annual cash flow by today's net equity, and rerun the number every year when you review your portfolio.

The second mistake is calculating equity as value minus loan balance and stopping there. On a $400,000 property, a 6% commission plus about 2% in closing costs and concessions removes $32,000 before you see a dime. Fix: net equity equals value, minus loan payoff, minus 7% to 8% for selling costs. A related error is counting unrealized appreciation as cash return. Appreciation builds wealth, but it isn't guaranteed and it can't cover a vacancy. Fix: report cash return and total return as separate lines, and use a conservative appreciation estimate.

Investors also compare a pre-tax hold return to an after-tax redeploy return, which makes holding look better than it is. Selling triggers capital gains and depreciation recapture, so the cash you actually redeploy is smaller than your net equity. Fix: subtract estimated taxes before running the redeploy scenario, or model a 1031 exchange as a separate option. Put both scenarios on the same tax basis before choosing.

Another trap is assuming a cash-out refi works without rerunning NOI against the new payment. A $280,000 loan at 7% over 30 years costs about $1,863 a month, or $22,356 a year. If NOI is $19,800, your debt service coverage ratio is 0.89 and the property now loses money. Fix: calculate DSCR (NOI divided by annual debt service) and look for 1.20 or better before you sign.

Finally, investors free up equity and pour it into a flip without verifying ARV and rehab. Overstate ARV by $25,000 and underestimate rehab by $15,000, and a $40,000 gap can erase years of rental gains. Fix: pull adjusted sold comps within 0.5 miles, price rehab line by line, and apply MAO = (ARV x 0.70) minus repairs. With a $300,000 ARV and $50,000 in repairs, your ceiling is $160,000. FlipSmrt runs that comp, rehab, and MAO math in a few minutes, so you can check a deal before you commit the equity.

FAQ: Return on Equity and the Hold-or-Sell Decision

What is a good return on equity for a rental? There is no universal number. The useful benchmark is what that same equity could earn elsewhere with similar risk and effort. If your rental produces $9,200 a year on $200,000 of equity, that is 4.6%, which may be close to what a passive, low-risk account pays in some rate environments, with no tenants or repairs. Most investors want ROE clearly above that baseline before they consider the equity truly productive.

How often should I recalculate ROE? Do it at least once a year, ideally when you gather numbers for taxes, because rents, insurance, property taxes, and market value all drift. Also rerun it after a major repair, a rate drop that makes a refi viable, or a jump in nearby sale prices. Base your value on recent sold comps rather than an automated estimate. On $200,000 of equity, a $30,000 error in value shifts your ROE by more than half a point.

Should principal paydown count toward ROE? Yes, as long as you treat it consistently. Paydown is real wealth, but you cannot spend it until you refinance or sell. Track two figures: cash ROE (cash flow only) and total ROE (cash flow plus paydown). If the deal only looks acceptable on total ROE, your returns are mostly illiquid.

Is a low cap rate on current value a reason to sell? Not by itself. Cap rate (NOI divided by current value) tells you what a buyer would earn today. A low figure means your equity is earning little relative to what the property is worth. Selling, however, costs roughly 6% to 8% plus capital gains tax and depreciation recapture, so compare net proceeds redeployed, not gross value.

What if I sell and cannot find a better deal? This is the real risk. Cash sitting idle earns less than the rental did, and the 45-day identification window in a 1031 exchange can push you into a mediocre property. Find and fully underwrite the replacement before you list. Recalculate ROE every year, and only move equity when the replacement deal's verified numbers clearly beat the hold after taxes and transaction costs.
