Because people have more money, making more expensive things more affordable. Demand isn't a single number "I need one apartment." It's a curve: at $0/month I will live with my parents. At $800/month I will live with a roommate. At $1200/month, I will rent a 1 br. At $1500/mo, I will rent a 2br. At $2000/month I will not rent anything because I do not have $2000/month. etc. And actually, it's a curve representing how many people are willing to pay for a thing (or how many things they want) at a given level, not how many apartments do you, one person, need. Now give everyone $2000/month, and their ability/willingness to pay will increase. Maybe you figure now you can move out of that dodgy neighborhood into something nicer. Except the person who could already afford the nicer apartment pre-UBI isn't going to downgrade to the dodgy one, and they get UBI too, so they'll just pay more to outbid you (they would move upmarket themselves to make room, but it's turtles all the way down). Of course every sector of the economy knows this, not just landlords, so in reality prices of everything will rise rather than rent capturing it all.
