Why are home prices still rising?

Why are home prices still rising? It is a simple answer. There are more purchasers in the market right now than there are available homes for them to buy. This is an example of the theory of “supply and demand” which is defined as:
“the amount of a commodity, product, or service available and the desire of buyers for it, considered as factors regulating its price.”
When demand exceeds supply, prices go up. This is currently happening in the Staten Island residential real estate market.
