I have purchased in this part of Prague. The propery was finished earlier this year and was let out straight away. I have visited the area a few times and have inspected the finished apartment and tenants which were placed as part of a rental agreement arranged alongside the purchase.
As mentioned above there are a number of developments around the docklands area which will not be finished for a number of years, inlcuding offices, shops, restaurants etc..
I have not had the property revalued as yet and at the time I was purchasing there was a new law being introduced around VAT on properties which I was exempt from at the time but I think it has been introduced since. So this is worth looking into.
So far it has seemed to work quite well as there was a large amount of interest in the rental market in the area, I have not yet studied the resale market whcih is of course the important part if you are looking for a quick return. From figures provided by the agent i used and also from self study, the market has performed very well over the last few years and is expected to do so for a few years to come.
Prague is a very expensive city and the standard of living is much higher than other parts of Chez republic or eastern europe, so with this comes good rental and hopefull resale markets.
