Simplified assumptions: you live in the flat, so no rent is counted — neither received nor saved (the rent you no longer pay is not income in this calculation). The capital gain is exempt only if the flat is still your main home (résidence principale) on the day of the sale (CGI art. 150 U, II-1°). The part of the down payment not spent on the purchase earns nothing. The details are in the detailed report.
