The property-owning company is a common device here as it's required by all non-EU citizens wanting to own a house with some land. Typically, these are non-trading entities as they merely hold the asset (or assets, if you have several houses or include vehicles too).
If you want to undertake business activity (i.e. trade in some way), I recommend you incorporate a separate company rather than mixing the two. But, of course, the trading company must file a return, so including its assets is not a big stretch (if you prefer to mix).
The company does have expenses such as property tax, garbage fees, electricity, water, etc. However, I'd guess most folks don't bother to do formal bookkeeping/accounting to keep track (and try, where possible, to put these bills in their personal name as this can be cheaper than the commercial/business rate).
Income from the property (e.g. rent) would count as trading, but otherwise it's dormant / non-trading, and it simply owns an asset.
@JimJ is correct that accounting is much simplified for dormant / non-trading companies, but I'm not sure that you don't have to file ANY returns. My understanding is that you should file for the FIRST accounting period of dormancy, but thereafter you are exempt.
This is covered by the Bulgaria Accounting Act (Article 38, paragraph 9) which mandates that companies without business activity during a reporting period must submit a one-time declaration of inactivity to the Commercial Register.
I'm not sure it's super difficult to do yourself, as you can file online.
They have a bunch of documents and declarations.
This one is Article 38 para 9 accounting act (i.e. dormant)
This form, translated, says:
