Coming in with a tiny average home size of just 560 square feet (52sqm), Paris also has some of the highest residential real estate prices in the world.

For apartments, the average sale price ranges from €855 ($911/£707) to €1,421 ($1.5k/£1.2k) per square foot, or €9,200 ($9.8k/£7.6k) to €15,300 ($16.3k/£12.7k) per square metre. Houses, which are rarer, cost between €910 ($970/£753) and €1,951 ($2.1k/£1.6k) per square foot, or €9,800 ($10.5k/£8.1k) to €21,000 ($22.4k/£17.4k) per square metre.

For example, this one-bedroom apartment in the 15th Arrondissement – typical for the city's median size – was recently listed by Cabinet Bonvallet for €598,000 ($626k/£498k).
