Huh? What does that have to do with my post?
I said the availability of lots of rental properties is beneficial to everyone involved, and there are more downsides than upsides to this.
Most people, especially young people with the least money, don't just start out with a job they'll have forever in a neighborhood they'll live in forever or even want to. They move and change jobs several times, so renting is much better for them because you have to live in a house for several years before buying is a better deal than renting.
There are more additional expenses to owning than renting, and now young single people have much higher up front costs, wouldn't even necessarily be approved for a home loan without any credit history or enough money for down payment, furnishing the house, appliances, any repairs, which there certainly will be for any home a poorer person could come close to affording just the closing costs for.
Don't know in Holland, but if this was the case in the US, it would only increase rent, leave more homes abandoned, and lead to a massive increase in home repossessions.
