If you are going to live in your village house all year round thats fine but if not dont bother because you will get burgled. Also as its been said barking bl**dy dogs 24 seven,also be smart do not buy anywhere that has gypsies.
You will need to at least try and learn Bulgarian lingo.
Dont expect decent roads there isnt many, dirt tracks at best ok for donkey and cart and stray dogs.
Bourgas is ok nice place in the summer bit dull in winter when it shuts.
Varna is best good all year round with decent shopping and sea views still loads of stray mutts and maniac drivers trying to avoid the stray pedestrians on zebra crossings, wear flat boots on the pavements or break an ankle or two. Not forgetting loads of ladies of the night.
