I disagree, landlords are price takers. There is not much I can do to drive my rents up if no one wants to pay it. If my rents are below market, I can get them up to market. But pushing it beyond that is competitive based on location and how nice the unit is. Honesty the best thing I can do is to build more units on the land I own. That is challenging though so it takes time and capital. You can thank single family home zoning and how difficult the city makes it to build for the rising rents. The landlords I know are very pro building. 14 units is more income than 4.
