The #1 Tax Mistake when People Sell Their House

Why It Matters

Missing the residency requirement can trigger a six‑figure capital‑gains tax, dramatically reducing net proceeds and altering homeowners’ investment strategies.

Key Takeaways

• Primary residence exemption up to $250k/$500k capital gains.
• Must live in home 2 of last 5 years to qualify.
• Converting to rental can forfeit exemption after three years.
• Test‑drive rental up to 12 months without losing benefit.
• Timing sale before exemption expires avoids six‑figure tax bill.

Summary

The video warns homeowners about a common tax trap when selling their primary residence, focusing on the capital‑gains exclusion that can eliminate federal tax on up to $250,000 for single filers or $500,000 for married couples.

The rule requires the seller to have lived in the house for at least two of the five years preceding the sale. If that condition is met, the profit is tax‑free; otherwise, the full gain becomes taxable, potentially creating a six‑figure liability.

The presenter illustrates with a $200,000 purchase sold for $700,000, yielding a $500,000 gain that would be entirely exempt for a married couple. He cautions that converting the home to a rental for more than a year can break the two‑year residency test, turning the exemption into a costly mistake.

Homeowners should time any rental experiment or sale to preserve the exclusion, as the tax savings can dramatically affect net proceeds and long‑term financial planning.
