Advice asked: Dutch landlord causes problems with rental contract

I suspect the landlord is trying to avoid paying the tax on the income he's getting from the lease.

Not sure what she can do about it though without pissing him off.  Assuming she can find somewhere else, has she considered moving?

We are being told that the landlord has no any legal point to defend his case. My friend has an iron clad agreement. But the fact that the landlord is clearly trying to stay in the favorable tax position for him is quite nasty and very unfair. She would never ever rented this place with this on her back. Also I have understood this is a quite unusual move from a landlord perspective. The Dutch expat rental agencys are very clear about this. Anyway, thanks for your comment

Can't really comment on the expat rental market, never had to use them, we have always got our houses via the Housing Associations (our daughter got one from them within a week of moving back to Holland); maybe it makes a difference that my wife is Dutch.
