Hi Tom,
Yes 8,000 GBP(12,000 euros) would only be a down payment, but with tax write offs on loans and income from the rental of the property you could easily cover your outlays, all the while your property is increasing in value. Bulgaria, Albania and Brazil are those new emerging markets, where property sales are largely unregulated and scams are rife, this is not investing, its speculation, in my opinion you are better to hold onto your money.
