Say I am a developer. I have money to invest. I am going to add housing until no one will buy or rent. In a high-end market in a high-demand location, the return is enormous. In my town, Bedford, a builder can get $350 a square foot for a house. Spend $450k on building, plus a fee of $300k for a lot - you can sell that house for $1 million. That raises the value at that location, and raises the overall value of the neighborhood - ergo, existing housing gets more expensive. A homeowner can sell to a developer and get more because the lot is worth a lot. There are houses in my neighborhood that have sold for over $400K that were torn down to provide space for a bigger, new house. Same for renting: if a house-owner can get a certain price for an apartment because there is high demand for housing in the town, then she will. Adding more housing in that town will continue as long as there are more renters desiring to move in than there is housing available. The mere fact that a developer will invest is a signal that the housing market is desirable. Hundreds of rental units have been added to my town, and the rents have gone up. Now, the one variable that is difficult to gauge is: How much would rents have gone up if there weren't new units being added? I think overall more housing helps a lot - it is just that developers are not going to let the profit from building go down if they can help it, because increases on existing homes gives a developer more opportunities because owners are more likely to sell to a developer who isn't asking to have the house upgraded or bringing in inspectors to get the sale price down.
