As a second home owner in France, the following consequences of Brexit may be important to you:
Therefore, if you wish to travel to your property on a regular basis, you should apply for the special Brexit Withdrawal Agreement Carte de Séjour (residence permit). This does not automatically make you a tax resident of France (unless you also fulfil one of the principal rules of tax residency) but will enable you to travel to France in the same way as you did prior to Brexit. For details of how to apply for the residence permit:

In 2018, the French government reduced the social taxes from 17.2% to 7.5% for EU and EEA residents. Therefore, from 2021, British residents will have to pay 17.2% social taxes on net rental income.
On a positive point, however, the double tax treaty between the UK and France does not change and a tax credit is applied in the UK to avoid double taxation on French rental income.
A second consequence for British citizens reselling their French property is that they will also be required to use a fiscal representative for all sales in excess of €150,000. This is an obligatory service of verification, for which the fiscal representative takes a fee in relation to the amount of CGT payable.
