You are obviously very good friends with these escorts who own these properties! I wouldn't have a clue who owns the apartments I visit — I always assumed the ladies just rented them. I would have thought mortgages and the likes would just complicate things too much for them! As for them then charging other escorts at 3-4 times the normal weekly rates — why would an escort pay say €2000 a week for an apartment that is only worth €500 a week? That makes no sense to me at all
