Yes, but at the same time it should not be possible for them to pass those costs on to people renting the house; rents should be fixed, or based on things like floor space and amenities.
But personally I think everyone should have a way in to the housing market. Renting is throwing away money; it goes into someone else's pocket and it's gone. When you buy a house you pay off a mortgage on the one hand, and (in today's economy) your property appreciates in value. Combine that with the issue that over here, a mortgage is cheaper than rent, and you can see how it's a huge issue.
I've spent something like €50.000 in rent before I finally bought a house; part of that was because I didn't want any longer term commitments, part was because I couldn't afford a house because even then the price of housing was going up sharply already. That's a lot of money that I'll never see again.
