Unfortunatelly, I can not tell that we are expecting increase of inventory in near future. Because of the low inventory and flexibility of the banks, who starts offering to homeowners refinancing, it is not too many propertis coming to market right now. The most of experts saying , and it is my opinion too, that we can see increase, when more builders involve and start building new houses, but it is going to take a time.
My advice is to buy now. You still can find a house on decent price.
