Along with Rome and New York, Paris is the world's number one city for tourists, with 16.3 million tourists in the previous year in which 9.7 million were from overseas. It's amazing that hotels, hostels and rental apartments in the city are occupied throughout the year.

Paris Tourism Office says that the number of the visitors will go up to 20 million by 2020. With Sydney and London, Paris was just polled as the third most beautiful city in the world, with a long and a different history, popular buildings and sites in the world. Besides the Eiffel tower, there is the Arc de Triomphe, Notre Dame Cathedral and the Louvre.

12 to 20 percent of the jobs in the Parisian economy depend on tourism.

According to investment website Property Frontiers, properties in the city "are still affordable", being "around 60 per cent cheaper than in central London, when compared on a like-for-like basis".

Prices differ with location and condition of the property, but a price of £254,000 for a one or two bedroom apartment in the city centre is common, while a similar property requiring substantial renovation can be had for around £120,000.

Property Frontiers also says that there is a severe shortage of rented accommodation in Paris" and said that the city is never short of prospective tenants. Observing the landlords, the dealers at the company have advised that gross rental yields lie between 4.5 and 8 per cent a year.
