My Bulgaria has easily the largest database of properties for sale in Bulgaria with more than 25,000 currently being advertised. By default the ‘average property prices’ database is as accurate a survey as probably exists anywhere. It can be found here and may prove a useful guide to potential buyers on average prices by town/region:

Remember that the average prices quoted are calculated on 1-3 bedroom Villas and Houses listed by agents on My Bulgaria only and DOES NOT include apartments etc.
