France’s busiest, wealthiest and most densely-populated region, Ile-de-France boasts everything a property investor could wish for. Year-round demand for vacation rental properties is unsurprisingly enormous and with so many iconic towns and cities within the Ile-de-France, common sense suggests it to be a genuine mecca for investment. In reality, rental yields across Ile-de-France have been on decline in recent years, although property values are sliding, making it relatively affordable for investors, while rental income tax is uncharacteristically low.
