Ya, isn’t that what supply not keeping up with demand (in the form of money that can be applied to said demand). Everyone can’t afford to rent an apartment f there isn’t enough apartments to rent. People will use their buying power to prevent being the ones left without, while landlords will benefit from bidding wars by being able to raise prices. That works in Seattle or austin even if it doesn’t work in Detroit or Shreveport.
People will bid up apartments because they have more money.
