Why do all agents always say sell and give there contact information? In my area, Flushing, prices seem to be falling dramatically for 1 family houses but not so much for 2 family homes. In my own case, Zillow shows a drop in value of my house of 70k in the last month. Crazy, but it is what it is. So essentially, the answer is really dependent upon if your house is a one family or a two family. If its a one family, then the near term prospect is not good, but if it is a two family, then you are better off.
The second question I notice the real estate agents DID not answer. Of course, it again is complex. If you are selling, it is better to hope neither happens, but you have little control over rates so you can only lower your price. If you are buying, it is always better to negotiate a low home price than a better interest rate. The interest rate can always later be renogiated down if rates fall, the price never can be. But again, you want both prices low and interest rates low, and who is God that they can perfectly determine this perfect conjunction?
