For one example of the different expectations. I think there's going to be more expectation to fix up your apartment yourself (like a house) than most people assume comes with an apartment.
And I don't get the impression Mathias is the hand holding sort in anyway.
That will leave a number of people needing to put more money and time into this than they expected.
Anyone thinking this is a simple buy to let are going to be disappointed, it's a fixer-upper.
And finding 200 people wanting a remote Bulgarian fixer-upper will be tough.
I'm not surprised they're struggling to sell them all even at the extremely low prices on offer.
