$300K of Equity: 1031 Exchange or Cash-Out Refi?
You bought at $250K, the property's worth $475K, and you have $300K of equity sitting there. Trade up via 1031, refi to extract cash, or split the difference?
You bought a Cleveland duplex in 2018 for $250,000 with $50K down. Seven years later, it appraises at $475,000. Your remaining mortgage balance is $175,000. Cash flow is $850/month — solid but unspectacular.
Run the equity math:
- Current value: $475,000
- Mortgage balance: $175,000
- Gross equity: $300,000
- Selling costs (~6%): ($28,500)
- Net cash if sold: $271,500
You have $300K of equity sitting in a single property. Federal tax law gives you two ways to redeploy it without writing a check to the IRS — and one way to do both at once.
A turnkey 6-unit lands on your desk for $1.05M in a Columbus suburb. Pro forma cash flow at 25% down: $2,400/month — almost three times what the duplex throws off.
Three paths to fund the down payment:
- 1031 exchange: Sell the duplex, defer ~$45K in capital gains + ~$22K in depreciation recapture. Reinvest $271K. Take an $810K loan on the 6-unit. Done.
- Cash-out refinance: Refi the duplex to 75% LTV ($356K loan). Pull $181K cash tax-free. Use it as 17% down on the 6-unit (smaller deal — $1.07M won't pencil at 17%, you'd need to find a $725K property instead).
- Hybrid: refi + new acquisition: Same refi as above, but buy a $725K 4-unit instead of the $1.05M 6-unit. Keep the duplex AND add a new property.
The IRS will let you defer $67K in tax through option A. The bank will let you keep $100K of cash flow through option B. They aren't the same play.
Run the 1031 exchange. Sell the duplex, identify a replacement within 45 days, close within 180. Defer $67K of combined cap gains + recapture, reinvest the full $271K net proceeds, and take down the $1.05M 6-unit. Bigger asset, larger cash flow, full tax deferral. You lose the 5% mortgage on the duplex and pick up 7.2% on the new note.
Cash-out refi the duplex. Pull $181K out tax-free, keep the duplex (and its 5% locked-in rate), buy a smaller 4-unit at $725K. You preserve the cheap mortgage on the original property, you skip the 1031 timing pressure, but you've now got two loans where you could have had one — and the after-refi cash flow on the duplex drops to ~$200/month.
The hybrid: refi + buy. Same as B, but you treat the $181K cash extraction as a working capital reserve, not a down payment. Buy the 4-unit with 25% down ($181K) and hold the duplex. Six months later, when you've stabilized the 4-unit, refi IT for cash to fund the next deal. You're trading bigger one-time leverage for compounding optionality.
What the Tax Math Actually Costs
Most investors size up the 1031 exchange by the headline number — $67K of deferred tax — and stop there. That's the wrong frame.
The 1031 doesn't eliminate the tax. It defers it. When you sell the replacement property without doing another 1031, you owe the deferred amount plus whatever new gain accumulated. The math is closer to a tax-deferred IRA than a tax-free Roth — and like the IRA, the eventual bill compounds with the asset.
For a long-hold investor planning to die owning the portfolio, the 1031 is genuinely tax-free — your heirs get the step-up in basis and the deferred tax is forgiven. For an investor planning to sell and retire on the proceeds at 65, the 1031 is just a deferral that earns time-value of money on the deferred amount.
Why Option B Is the Lazy Default — and Often Wrong
The cash-out refi feels safer because there's no IRS clock, no 45-day identification, no qualified intermediary. You sign refinance docs, get a check, redeploy.
What gets lost in that comfort is the cash-flow math.
The duplex throws off $850/month at the existing 5% mortgage on $175K. Refi it to $356K at 7.5% (the going rate for an investor cash-out in 2026), and the new payment jumps from $1,409 to $2,489 — a $1,080/month increase. The duplex now nets ~$(230)/month from a previous $850. You've extracted $181K but converted a positive-cash-flow asset into a slightly negative one. The new 4-unit has to make up for the loss before any of the leverage helps your portfolio.
If the 4-unit pencils at $1,500/month after debt service, your portfolio cash flow improved by $420/month for $181K of new leverage. That's a 2.8% cash-on-cash return on the extracted equity, on top of whatever appreciation you get on the 4-unit. It's not bad. It's also not a slam dunk.
Why Option A Is Better Than It Looks
The 1031 path's hidden advantage is basis efficiency. When you sell the duplex and roll into the 6-unit, your basis in the new property is the original $250K basis (less accumulated depreciation, plus the additional cash invested), NOT the $1.05M purchase price. That's bad for future depreciation but good for your immediate position — you're not paying tax on the $225K of appreciation OR the $80K of accumulated depreciation, and you've moved into an asset throwing off $2,400/month.
The cash-on-cash math: $271K invested produces $2,400/month — 10.6% before financing, mid-teens after.
Compare to Option B: you've levered up but kept a stale asset. The duplex appreciation slows at $475K (it's already at the top of its market). Your blended cash flow is $1,720 ($850 from duplex assuming you hold rate down + $870 lower number on the 4-unit because of higher debt service). The 6-unit alone in Option A throws off more.
When Option C Wins
The hybrid is the right answer for one specific investor: the one who isn't done buying.
Option C accepts a slightly worse single deal in exchange for rapid redeployment optionality. You keep the duplex (with its old 5% rate intact), refi a year later when you've improved the 4-unit's value, and use that extracted equity to fund deal #3.
The math at year three:
- Year 1: Buy 4-unit ($725K) with $181K from duplex refi
- Year 2: Force appreciation on 4-unit through rent bumps + light value-add. Now worth ~$825K.
- Year 3: Cash-out refi the 4-unit at 75% LTV — extract another $80-100K. Use it as down payment on a single-family flip OR a fourth small multi.
In three years you've gone from one property + $300K dead equity to three properties + ~$50K of working liquidity. Option A produces one bigger property with no easy path to deal #3.
The Real Question
The decision turns on what you're optimizing. Option A optimizes for the size of one asset. Option B optimizes for raw leverage. Option C optimizes for the velocity of capital across multiple deals.
If you're planning to slow down acquisitions and let the portfolio compound — Option A. If you want exposure to a second property with minimal tax friction — Option B. If you're three years into a five-year scaling plan and the next deal isn't this one, it's the deal after this one — Option C.
The tax savings are not the strategy. They're how you fund it.
- The 1031 exchange defers tax but locks you into a 45-day identification window and resets your basis to the new property's adjusted price
- A cash-out refi extracts equity tax-free but reduces monthly cash flow proportionally — a $181K refi at 7.5% adds ~$1,275/month in debt service
- Depreciation recapture (taxed at 25%) is the silent killer in a sale — most investors forget it until closing
- 1031 is a debt-and-tax decision; cash-out refi is a leverage-and-cash-flow decision — they optimize different things
- Keeping the original property preserves the step-up in basis at death — a six-figure gift to your heirs that the 1031 doesn't fully replicate
