A buyer’s example
Estimate the annual building costs of a Dobrich flat
Suppose two Dobrich flats both suit your route to the centre. One is higher up with a lift and the other is nearer the entrance. Ask what you would pay regularly at each building and whether work has already been discussed on the lift, entry or roof. Check how the seller uses the heating and which equipment is part of the sale.
Add a realistic allowance for the building and flat before you compare the cost with a seasonal coastal place. For regular trips to the coast, try getting bags from your door to your parking spot and back. If one flat is only convenient when the lift is available, ask who maintains it and what happened during the most recent outage.
