Renters become more like homeowners when there is rent control. They essentially have an investment to protect. Their immediate financial situation (rent being due, much like a mortgage payment or property tax) is unaffected by neighborhood changes. The enjoyment of their neighborhood is affected though, and they seek to maximize this.
The difference between the controlled rent and the market rent is in some sense an income that the renter receives from the landlord. The higher the market rate rent, the greater this income will be.
Long leases may have a similar effect; this is voluntary rent control.
