> I'm not even sure renting homes in general is a good idea.
Let's review the situation here. 1) The large majority of the land in the area is zoned exclusively for single-family homes. 2) Some people don't have the money to buy, e.g. no down payment or bad credit.
That doesn't follow at all. If you reduce investment then you reduce production. The price only goes down if the cost of creating more of them goes down, unless you can remove so much of the demand that you no longer need to add more supply. The small percentage of single-family homes owned by corporations isn't that.
Nah. There's 30 homes and 30 people. 10 people own two homes apiece that they live in 50% of the time. That leaves 10 homes for the other 20 people to fight over, driving the price up. Pretty simple.
