I have been studying global markets and investing internationally for RE companies for 10 years and know the french market quite well.
The take away about France is as follow:
pros
- relative market stability
- stable currency (euro)
cons
- highest taxes to gdp in the world (capital gain taxes, transfer tax, income tax etc)
- extremely complex / opaque tax system and aggressive tax authorities
- widespread corruption around high profile transactions and construction permits
- 3 months transaction close due to high regulation burden
- local authorities have first look right to purchase the property you have under contract. The deal must be reviewed by the city to be allowed to move forward
- currently highly overvalued market by all metrics, price to income etc
- low appreciation and returns compared to emerging EU member states and US
(most RE companies offer annual returns around 10% (minus high taxes) for high risk speculative investments)
- extreme anti landlord legislation
Basically, if you love France and want a secondary residence sure go ahead, but otherwise, given the number of attractive alternatives available at the moment, i don't see any valid reason to invest in France unless you are french and unable to invest elsewhere. Even for french tax payers, much better opportunities exist a couple of hours outside of France in the eurozone..
