Income shown is a 4% sustainable withdrawal so the portfolio keeps compounding. Spending the full average return each month means selling shares and giving up the growth this whole comparison is built on.

The Equity Duel — 10-Year Race


Sell → S&P 500 (net of 7% selling costs)

Keep the house (value + rents reinvested)

Rental path = house value appreciating + NOI reinvested at the S&P rate. Pre-tax on both sides — see The Tax Angle below for why the sides aren't taxed the same. Educational comparison, not investment or tax advice.

The Tax Angle (Read This Part)


  • Selling now is tax-free. Because y'all lived in the house 2 of the last 5 years, up to $500k of gain (married filing jointly) is excluded under Section 121. The check at closing is the only fully tax-free money anywhere in this comparison.
  • That tax-free window doesn't slam shut when you move. It survives roughly 3 more years after move-out. Translation: you can rent the house for 2–3 years, find out whether you actually like being landlords, and still sell tax-free if you don't. Renting is reversible. Selling is not. That option is worth real money and it never shows up on the chart.
  • The S&P path is not tax-free going forward. Dividends are taxed every year and gains are taxed when you sell. The red line above is a pre-tax line.
  • The rental path has a tax shield, with a catch. Depreciation shelters a chunk of the rental income each year. The catch: if you keep it past the ~3-year window and sell later, the gain becomes taxable and the IRS recaptures that depreciation at up to 25% — though a 1031 exchange can keep deferring it.
  • Louisiana landlord reality. The day it converts to a rental, the homestead exemption goes away (property taxes step up) and the homeowner policy becomes a landlord policy. Both are already baked into the taxes + insurance number above — that's why it looks high.

I'm your Realtor, not your CPA — before pulling the trigger on any of these paths, run the tax side past a CPA. I'll happily join that call.
