One specific question I have is what is the time frame applicable to answering whether neighborhood values are increasing, stable or declining, on page 1 housing trend section of the report. The FNMA/fhlmc guidelines are vague on this topic, apparently intending to leave it open to interpretation. Reading appraisal blogs and guidebooks, I am getting answers ranging from it refers to the value trend over an extended period such as over a 3-6 year neighborhood cycle, others interprete it to mean over the past year, or even past month. I have always filled out the page 1 neighborhood trend boxes to reflect what is currently occurring in the market as of the date of appraisal, based on most current sales, current listings, current pendings, lp/sp ratios, days on market, supply vs demand, bidding wars, over asking price offers, etc. It is focused on what is happening right now.
IMNSHO, the minimum time frame that should be utilized for market trend analysis is for a year over year period (i.e.: current 12 month period vs. prior 12 month period) in order to compare apples to apples and account for seasonality in the data. Comparing the current 1 or 3 month period to the prior period (unless you adjust for seasonality, which can skew the numbers if the current trends are not in line with historical trends) can be very misleading in most if not all of the markets I cover.
For example, DOM tends to be shorter in the summer than in the winter; inventory tends to be higher in the spring when many place their homes on the market for the anticipated summer selling season, etc.
