I would suggest to you several options: 1. A big transparent on your terrace saying for sale and the price written on it. 2. Contact agencies and announce it for sale through them. Maybe even anybody in the forum could be interested in selling or buying it if you give more details about it.
we have a two bedroom apartment in sunny beach which we purchased last year,can anybody give us information on making out a will,how much this should cost and maybe a decent reliable lawyer who wont rip us off.
