All what I am trying to say is that we manage 6 classic apartments only(taken over from other companies) which are not "perfect apartments for rent". Therefore, your point of view that we have less success in renting classic apartments might be confusing.
The other point is that tax should be included in reasonable rent, otherwise it does not make sense to compare our rents to other companies' rent. What I mean is that net rent is very low in Budapest if your gross rent is also low.
The key point is that Hungarian owners do not pay tax plus tenant are not interested in higher rent just because of tax liabilities. This is a kind of commitment between tenants and landlords so rent without tax is more common in Budapest.
Tax is an issue if tenant is a corporation that needs a receipt. Thanks to net rent approach, unfortunately, market price does not include tax in most of the cases. I do not think we are able to change people's approach to tax but it is better to know what is your net return after tax and charges.
Do a calculation by yourself if you know taxation rules. You will be surprised that tax liabilites are extremly high (39% if your annual rent is over €4,000 - alternative 1 - but there are other 2 alternatives which can provide you real tax return). Please mind extra charges such as introduction fee, management fee, insurance, accountant fee, maintenance.
(For your information: 3 alternatives are offered to property owners of how to pay tax - you might pay more tax(probably 2 months' rent) if you are not updated on taxation rules!)
If we are talking about financial investments we should focus on net /absolute figures instead.
