Hi pope - i have recently bought in Krakow - €200k on a 125m2 apartment (yes that does sound expensive but it is in probably the most exclusive area of the city). The city is buzzing and I knew somebody there on the ground so felt comfortable buying in that city as opposed to anywhere else.
It's one of the biggest challenges buying in any foreign city - where exactly in the city to buy!
Anyway I got my mortgage through GE Money Bank. AIB also have an operation over there but they are very expensive. If I was going again I would seek out a mortgage broker as they will achieve best value and they are well used to foreigners buying over there.
In relation to Legals, I went through a large/prestigious firm over there where they're fluent in English and all documents are translated. Like a MOB over here. It was an expensive process but they were fantastic and they made me feel very comfortable with the purchase. I would strongly recommend this approach although it's not strictly necessary as they have a notary system over there. You could employ a solicitor here but I would need to be convinced they would add much value. They will certainly not indemnify!

Is it a good purchase? That's the key question. Fundamentals are good there, their aspirations are to catch up with Western Europe and all they need to do is shed off another layer or two of the past and off they go. Key thing to factor in is the Capital Gains Tax over there - it's 10% of the sale price, not the gain. So you need good gains over quite a period to make the investment stack up.
If you want to get specifics off me about Legal and Banking feel free to PM me. I have no association with them other than I used them once.
If you want additional information about sourcing property you can PM me as I do have commercial links to one agent over there.
