Do you mean expensive flats or expensive to put an add on?
I found the last three flats on homegate (and I always keep my fix-costs down) and put two successfully on there, it was about Fr. 100.00 franks then I think.
homegate is *the* website to advertise on for a solid serious impression on your future buyer/renter and it has the biggest audience. It's not cheap, unfortunately, that's true...
If you want to go cheap, there's enough small free websites around - simply look at what comparis.ch indexes. And then there are a few agencies around who'd put your ad on homegate for free in exchange for charging a commission to your buyer/renter, scaring most of them away in this way however
what a way to sound bias and shallow but....no! It does exists in America and few other countries. Any real estate agent will understand the concept of the question.
got'ya, well there is no such thing as an MLS system in this country, any and all listings go through real estate brokers / estate agents, and only they will be able to tell you who of their listings is an absentee owner.
My guess is that more than 80% of the rental properties are "absentee owners." Properly the largest management company is Livit.
But there also numerous smaller companies. just search for Liegenschaft-Treuhand and Liegenschaftsverwaltung.
If you are looking for a property which has not an absentee owner one indication is that the listing is not by a Treuhand, Verwaltung etc. but a private person. Unfortunately in many of this cases it is more likely a current tenant looking for a replacement.
