"present value of future benefits"
Ring a bell for anyone?
An investor's motivations and an owner's motivations are different. A residential owner needs to find someplace to live. Someplace reasonably close to work and, perhaps, reasonably close to a desirable, or acceptable, school. They don't have time to sit around until a deal is found that meets their investment requirements. They need to find someplace to live NOW.
In a buyer's market, there are plenty of options available. They don't have to get into a bidding war with anyone. They may have half a dozen or more VERY GOOD options, most of them having sellers that may need to sell NOW so that they can relocate to that new job, bigger house, smaller house, or whatever reason exists that has compelled them to disrupt their lives and relocate. Because of supply and demand, prices may be stable or may be declining.
In a seller's market, there are few options available. There are multiple buyer's who need someplace to live NOW. With few options available, prices get bid up. Sellers can receive multiple offers and, with professional advice from their agent, may select the option that represents not only a "good" price, but which is expected to close with minimal delay and trouble. For that reason, a cash buyer may realize a better price than a buyer with weak credit and limited funds. Regardless, because of supply and demand, prices are likely increasing. Depending upon the a variety of factors, including interest rates and buyer desperation, prices may be increasing rapidly. (Keep in mind that owners-users, particularly residential owner-users, buy on the basis of the most house they can get for the highest monthly payment they can afford. The actual "asking price" is essentially immaterial. The monthly payment is what matters.)
So, in an increasing market, if an appraiser fails to make appropriate market change adjustments, they have not valued the property for what it "should" bring today. They have valued the property for what it "should" have brought in the past.
So, JG, by your own argument in this thread, you have defeated your argument in other threads. It is what it is, not what it was.
Edit: I see Howard and I were stating essentially the same thing and the same time. Great minds think alike.
