Resources · Sell the rental
Should I sell my rental and stop working?
Short answerIt depends on how two paths compare on your numbers. Keep and collect: portfolio hits a reduced target while rental cash flow covers part of spending. Sell and invest: portfolio hits the full target using the after-tax lump sum. Neither path is a general winner. Higher net rent relative to sale proceeds tilts toward keeping; a shorter horizon to Optional also tilts toward keeping.
A rental sale stacks two decisions. Give up the cash flow, take the proceeds. Below: a calculator that runs both paths, a worked example, and the specific things the model doesn't capture (rent growth, mortgage amortization, appreciation past the sale) so you can weight the answer accordingly.
Calculator
Compare keep-vs-sell against your numbers
Type your numbers. Set the after-tax sale proceeds, the rental's net monthly income (after mortgage, tax, maintenance, insurance, and vacancy), and when you'd sell. The calculator shows the reduced target the keep path aims at, the full target the sell path aims at, and how the Optional Date differs between them.

A meaningful pull-forward. Selling helps, but the rental's ongoing income was doing real work.
Model Keep case: rental income covers part of your spending, so the portfolio only has to hit a reduced target ($1.57M) while you own the property. Sell case: cash flow stops, target snaps back to the full number ($1.88M), and the after-tax proceeds land in your invested balance as a one-time lump sum. If you actually save every dollar of rental cash flow instead of spending it, add that amount to "Monthly contribution" and set the rental net to zero.
Not modeled rent growth, expense growth, mortgage amortization, future capital expenditure, property appreciation past the sale date, taxable events on portfolio rebalancing, or the risk difference between a diversified index and a single property. Treat this as a directional check, not a final answer.
Assumes a 7% average real return (after inflation) and a 4% withdrawal rate.
Two paths, two different targets
The keep path aims at a reduced target. Say your rental produces $12,000/yr net. At a 4% withdrawal rate, that's $300,000 the portfolio doesn't have to fund on its own. Instead of $1.875M (25 × $75K spending), the portfolio only has to reach about $1.575M. Once it does, rental and portfolio together cover spending.
The sell path aims at the full target. Rental cash flow stops, so the portfolio has to fund the whole $75K/yr and needs to hit $1.875M. It gets a head start from the after-tax proceeds landing all at once.
Which path wins depends on the specific numbers. Higher net rent tilts toward keeping. Larger sale proceeds relative to annual rental tilt toward selling. Longer horizon to Optional tilts toward selling, because compounding on the lump sum has more time to work. Read the "not modeled" list before trusting the result on a big decision.

What the trade looks like
Case study — Marcus, 46 — illustrative case study, considering a rental sale
Marcus has $520,000 in his 401(k) and brokerage. He saves $2,000 a month and spends about $75,000 a year. He owns a rental worth $400,000 with $80,000 remaining on the mortgage. After tax, fees, and paying off the mortgage, a sale would net him about $270,000. The rental brings in about $1,000 a month net of every ongoing cost.
Balance
$520,000
Monthly save
$2,000
Rental net
$1,000/mo
Sale nets
$270,000
Reduced target (keep): ($75,000 − $12,000 rental) ÷ 4% = $1.575M. Portfolio hits that in about 12 years, at age 58. Rental and portfolio together cover the $75,000/yr.
Full target (sell in one year): $75,000 ÷ 4% = $1.875M. The $270,000 lands in his brokerage and compounds; the $1,000/mo stops. Portfolio hits the full target in about 10 years. Roughly 19 months sooner than keeping.
If Marcus waits five years to sell: the rental keeps producing income while he waits, so the reduced target is doing work in those years. The eventual lump sum has less runway ahead. Sale lands Optional about 10 months sooner than keeping. Still a pull-forward, but much smaller than selling now.
If the rental produced $2,000/mo net instead: keeping wins. Reduced target drops to $1.275M, and the sale can't catch up. On these numbers, selling delays Optional by about 11 months.
A sense-check, not a rule: selling tends to accelerate Optional when the after-tax proceeds are large relative to the annual rental income and you're still years away from Optional. Neither condition alone decides it. The model deliberately leaves out rent growth, appreciation past the sale, mortgage amortization, and portfolio-rebalancing tax hits. Treat close cases as close, not decided.

The math
Assumptions and formulas
Same engine as the rest of the app.
Full target = Annual Spending ÷ 4%
Reduced target (rental owned) = (Annual Spending − Annual Rental Net) ÷ 4%
Each month, your balance grows and absorbs your normal contribution:
ending balance = starting balance × (1 + monthly return) + monthly contribution
+ (sale month ? proceeds : 0)
The keep path checks the balance against the reduced target every month. The sell path checks it against the reduced target until the sale month, then against the full target from the sale month on.
monthly return = (1 + 7%)^(1÷12) − 1 ≈ 0.565%/month
- Proceeds are after capital gains, depreciation recapture, closing costs, and mortgage payoff. Enter the net.
- Rental net income is after mortgage, maintenance, taxes, insurance, and vacancy. Not the gross rent.
- Rental income is treated as covering part of your yearly spending (target-reducing), not as extra you're saving on top. If you reinvest every dollar of cash flow, add that amount to Monthly contribution and set Rental net to zero.
- 7% real return on both the invested balance and the sale proceeds. Real-estate appreciation past the sale date isn't projected here.
- Rent, expenses, and property value are held flat in real dollars. In real life rent may grow with (or lag) inflation, expenses can spike, and mortgage principal reduces each month. None of that is captured.
- No new expenses on the invested side. If selling would force a real-estate replacement (buying a primary residence), model that separately.
- No taxes on portfolio rebalancing or withdrawal. See the methodology page for the current limits.
FAQ
What people ask about this
What if the rental appreciates faster than the market? Then keeping looks better than the model shows. Real estate that appreciates at 5%+ real for a decade beats a diversified index, and leverage amplifies that. It happens; it isn't the base rate.
Does the model include mortgage amortization? No. Principal you'd otherwise be paying down over time isn't captured on the keep side. The sale proceeds you enter should reflect paying off whatever's left today.
What about a 1031 exchange? Not modeled. If you're rolling into another rental, "sell" isn't the right question. You're not converting to investable cash. Compare the properties themselves.
Does landlording effort count? Not in the numbers. It should count in your decision. Managing tenants over a decade is real. The calculator shows the money side.
