So, you're saying there is a better place? Facts are, that the property market in both the entire EU and US has fallen apart with China soon to follow (tm). Prices were speculative and are falling down to a mere "high". In the next few years they'll fall to "affordable". Most likely that loss is taken over inflation which means everybodys money will just be worth less and that's fairly harsh on a population especially if it's already fairly poor and the basic necessities (food, water, shelter) becomes unaffordable. That's on a systemic level.
If you really want to invest in property, you'd be better off in Bulgaria, simply because the % loss in nominal currency would be much less. Want an example?
A worn down, mid 70's house here in Denmark is regarded as 'cheap' when it 'only' costs 1,8 mio dkk. That's around 250.000 euro. For the same house, in the same condition you'll pay around 25.000 euro in Bulgaria.
Prices drops 25% more? That's a 75.000 euro loss in Denmark. In Bulgaria it's 7.500.
Tip: Buy a house for living in it. Not because you want to earn on buying it to begin with. Everything you paid for a property you should consider "spent money". It's not like you're calculating the value of a leaf of bread after you bought it. Then again.. if you bought a leaf of bread 10 years ago, the price would have gone up 350%. (or more correctly, your money would be 350% less worth)
