Over recent years international property surveys often see Monaco quoted as the most expensive country in the world to buy an apartment, and those that don't have the Principality top will have it in second or third place.
When it comes down to street level, Monaco again frequently tops the surveys with Princesse Grace Avenue the most expensive street in the world to buy real estate.
So it would seem to make sense that Monaco is the most expensive tax haven in the world, affordable only by the ultra wealthy, as part of gaining residency in Monaco requires buying or renting a property.
Surprisingly though this isn't the case.

Helped by new rules for residency in Andorra, Monaco can be as inexpensive as its main competitor in Europe with a distinct advantage of being close to the European transport system, including the rail network and an international airport.
With Andorra requiring a 400,000 Euro minimum investment in government bonds or buying an Andorra property to that value, or a mix of the two, how can Monaco compete to attract those looking for a tax haven in Europe?
The answer lies in how the applicant approaches residency and property in Monaco, and how long he or she needs a tax haven for.
Given that many of those wanting to move to a low tax jurisdiction only need it for five or six years before they can return home the answer is in renting, and choosing one of the Monaco banks that takes a low initial deposit to secure a certificate showing that the applicant has sufficent funds to be able to look after themselves financially.
A one bedroom apartment in a relatively good building with sea views and a parking space will cost around 3,000 Euros a month - for two bedrooms the current rentals start at around 5,000 Euros a month.

Part of being accepted as a Monaco resident is showing the ability to support yourself financially, and this is done by getting a certificate from one of the Monaco banks showing that a deposit has been made.
Different banks ask for different amounts, and these vary widely from bank to bank, but one of the leading ones is able to produce the certificate with a deposit of 100,000 Euros.
So for someone wanting residency in Monaco the cost of renting a one bedroom apartment for five years would be 180,000 Euros plus 100,000 deposit for the bank (which the applicant keeps).
Or for a two bedroom apartment 300,000 Euros, again plus a 100,000 Euros deposit which is returnable when residency is rescinded.
With the changes made in Andorra in 2012, they could be the losers as those wanting to move to a tax haven realise that Monaco is just not affordable, but more affordable than its main competitor.
