The standard bit of misinformation used to peddle ski properties is the "summer use" one, but the reality is that it just doesn't happen. Go to any ski resort in Europe in summertime and what do you find? Deserted, like the Black Sea in wintertime, everywhere locked up and nobody around. The reality is that the number of summer visitors in ski resorts,even in well-visited places like Austria, is just a tiny fraction of the winter business. I have heard this line peddled at property shows to gullible buyers, and it works every time.
You are making dangerous assumptions regarding your investment. You have already in your mind stretched the season out to the times when there will be no visitors. You have also used the "guaranteed rental" figure (itself a nonsense, as anybody who has examined it in any detail will tell you) to set a benchmark for your rental income. You are also assuming full occupancy, again not a reality in any holiday market and even less so in the ski market. You are making no allowance for management fees, rental commissions, cleaning, laundry, heating, etc, all of which will rise significantly as Bulgaria catches up with European costs.
In any market, be it London, Dublin, Budapest or Bansko you need to make investment decisions based on the local market norms. No Bulgarian is going to pay either the grossly inflated price you paid for this property, nor is he or she going to pay 700 euro a week for 20 weeks a year in rent for it. You are simply in denial about having been caught by the snake-oil salesmen who peddle this rubbish to "investors", you have been scammed out of a lot of money and you won't see half of it back when you try to exit. That's the reality, regardless of what comfort you derive from owning a holiday home in Bulgaria.
Let me tell you what will happen here. When your two year "rental" period is up, the realities will slowly begin to dawn on you. You will have a 2 year old property, the few renters in the market will be looking for the new places that will have been built since then, the salesman who was your best pal through all of this won't be anywhere to be seen, and the fixed costs will have risen alarmingly. You will hold on for about three more years (typically), throwing money at the place to pay the management fees and taxes, and then try to sell. A year later you will agree to drop the price to get a sale, and eventually will accept a much lower offer to get out with as much as possible of your original money. How do I know this? Saw it all before, Bulgaria wasn't where this kind of garbage was invented, just where it was brought to an art form.
I am not being negative, just realistic. I do think that its a pity that at a time when Irish people have the wherewithall to invest in their own futures, they chuck their money away on the property equivalent of junk bonds. Still, its their money...
