Should I sell my US house before or after moving back to Europe?
Short answer: Selling your US home *before* you lose US tax residency is usually better. It allows you to use the full Section 121 exclusion ($250k/$500k of gain tax-free) and avoids FIRPTA withholding (15% of the sale price) that applies to non-resident sellers. Additionally, some European countries may tax the gain if you sell while a resident there.

Why it works this way
The Section 121 exclusion is a powerful US tax benefit, but you must have lived in the home for 2 of the last 5 years. If you move to Europe and wait three years to sell, you lose this exclusion entirely. Selling while you are still a US resident ensures you capture this tax-free gain before you fall under the tax regime of your home country.
FIRPTA (Foreign Investment in Real Property Tax Act) is an administrative hurdle for non-residents. If you sell after you have left and abandoned your green card or visa, the buyer is required to withhold 15% of the *gross* sale price and send it to the IRS. While you can eventually get this back if your tax liability is lower, it can create a massive temporary liquidity gap.
European taxation of foreign property varies. France and Germany generally have the right to tax the gain on a US property sale if you are a resident at the time of sale. While the treaty may offer a credit for US taxes, if the US tax is zero (due to the 121 exclusion), you might end up paying the full European capital gains rate on the sale.
The expensive mistake: Converting the US home to a rental and selling years later
While keeping a rental can provide USD income, it often destroys your tax efficiency. You lose the Section 121 exclusion, trigger 'depreciation recapture' tax in the US, and become subject to complex foreign reporting and taxation on the rental income and eventual gain in your home country.
What to do
- Calculate your potential gain and exclusion — Determine if your gain is within the $250k (single) or $500k (married) limits to see if the sale will be tax-free in the US.
- Time the sale to close before your residency change — Aim for the closing date to fall while you are still physically in the US and considered a tax resident to avoid FIRPTA.
- Consult a tax advisor in your home country — Check if your destination country has a 'step-up' in basis for properties owned before you became a resident, which might mitigate the tax if you sell later.
