When your property stands empty, the most visible loss is the missing rent. But vacant property costs in Bulgaria also build up elsewhere: local fees, utilities, maintenance and preparation. This article shows you how to calculate the real cost of one month without a tenant, and how to use that number when you decide whether to lower the rent.
It is written for foreign and expat landlords, so Bulgarian terms are explained as they appear.
Vacant property costs: what builds up every month
Many landlords count only the lost rent. That makes an empty period look cheaper than it is. Some costs that the tenant normally pays fall back on you while the property is vacant.
There are four main components:
- Lost rent – the amount you would have received if the property were let.
- Fixed fees – local taxes and charges (for example the municipal waste fee, known as такса смет), plus contributions to the building's owners' association (етажна собственост) if you pay them.
- Utilities – electricity, water, heating, internet. Even an empty property has subscription and minimum charges.
- Maintenance and preparation – cleaning, small repairs, listing photos and possibly repainting between tenants.
Exactly which fees you owe depends on the municipality, the building and your lease. Check your latest bills and the decisions of the owners' general meeting rather than relying on rough estimates.
The formula for one empty month
The method is simple and works for any property:
Cost of an empty month = lost rent + fees + utilities + maintenance
Use real data for each component, not impressions:
- Rent – the last agreed rent, or a realistic market rent for comparable properties.
- Fees – divide the annual amounts by 12 and add the monthly contributions to the building.
- Utilities – look at the bills from previous vacant months, or from tenanted months, and separate out the fixed subscription parts.
- Maintenance – divide your average yearly repair spending by 12, or set aside a sum for preparing the flat after a tenant leaves.
If you own more than one property, calculate each one separately. A two-room apartment and a studio have different fees, and a different likelihood of letting quickly.
A hypothetical example
The following numbers are an example only, to illustrate the method. They are not market data.
Assume an apartment with a rent of 600 € per month. During a vacant period you bear:
- waste fee and contributions for common areas: 45 €;
- electricity, water and internet (subscriptions and minimum usage): 25 €;
- a sum set aside for maintenance and preparation: 30 €.
The additional costs are 100 € per month. Together with the lost rent, an empty month costs 700 €. If the property stays empty for two more months, the loss is 1,400 €.
Note that of this 700 €, only 100 € are actual payments from your pocket. The remaining 600 € is income you did not receive. Both affect you, but it helps to see them separately so you do not confuse missing income with real cash outflow.
How the number helps you decide on a rent reduction
The key question is: what does a reduction cost compared with waiting? Compare the two amounts.
In the example, you lower the rent from 600 € to 570 €. That is 30 € less per month, or 5%. Over 12 months the reduction costs you 360 €. One additional empty month costs 700 €, and two cost 1,400 €.
You can also work backwards: divide the cost of an empty month by the size of the reduction. Here 700 € against a difference of 30 € means one empty month costs as much as a little over 23 months at the lower rent. So if the reduction genuinely shortens the search by at least a month, it often comes out ahead.
This is not a universal rule. Also consider:
- how many viewings you have held, and how many ended in a refusal because of the price;
- comparable listings in the same area – see, for example, rent in Sofia by neighbourhood if your property is there;
- whether the lower rent might stay in place for longer than you planned;
- other ways to attract tenants – included utilities, a flexible term, a small repair or better photos.
Sometimes the cheaper fix is not a reduction but a better listing. If viewings are missing, the problem is rarely only the price.
Checklist for the vacant period
Use it on the day your tenant moves out:
- Record the move-out date and sign a handover protocol (приемо-предавателен протокол) with the meter readings.
- Collect the latest bills and work out the monthly fees and utilities.
- Set the market rent from comparable listings, not from the last rent.
- Calculate the cost of an empty month with the formula above.
- Set a deadline – for example, how many weeks you will wait at the current price before reviewing it.
- Before the decision date, calculate what the reduction would cost over the whole term of the lease contract (договор за наем).
- Track enquiries and viewings. If enquiries are many but viewings few, review the listing; if viewings are many but nobody commits, review the price.
- When you find a tenant, review the lease and the deposit in advance so that paperwork does not delay the move-in.

What not to overlook
First, do not treat lost rent as a tax loss. How rental income is taxed and what you can deduct is a separate subject – see rental income tax in Bulgaria, and if in doubt consult an accountant or НАП (the National Revenue Agency).
Second, mind the type of your previous lease. If the former tenant paid the utilities, check that you have complete data for them before you calculate the cost of the empty period.
Third, revisit the number regularly. The cost of an empty month changes with the season, the bills and the rent, so do not calculate it once and treat it as final.
