TE & Edd-
I don't think it takes a lot of effort to provide some summary; of course, the problem occurs when I think the data is self-evident but the reader/reviewer doesn't.
Case in point: I just completed an appraisal of a home located in a nice area on a busy street. Owner's estimate $810k. My value $685k. Issues were:
A. Garage converted with permits, so the house is larger than what's typical along this busy street.
B. Because of the converted garage, subject has a carport; this is not typical in the neighborhood.
C. Subject has had some nice upgrades and looks good interior/exterior.
D. Original models were around 1,050sf, 3br/1ba. Subject is now 1,440sf, 4br/1ba.
I know where the owner got his estimate: from the homes that are not physically far from his (1-2 blocks), well insulated from the noise/traffic, and were originally built as 3/4br-1.5 to 2 bath homes from 1,300 to 1,550sf. (Naturally, there is only one at $800k, the rest are $730k to $760k).
If one were to focus on GLA alone, one would conclude a higher value.
If one were to focus on Condition alone, one would conclude a higher value.
If one were to focus on location alone, one would conclude a lower value (original 1,050sf models on same street, upgraded to similar condition, sell for $650k+/-).
If a reviewer looked at the report and was not familiar with the neighborhood, she/he might conclude it warranted a higher value. Also, there was one sale with the same street name, larger- 4br/2ba, that did sell for $770k; however, that sale was in the neighboring city on a part of the street that didn't have same traffic influence and in a different neighborhood. It was not comparable.
So, to "summarize" the issues, I wrote the following:
The subject's market value is influenced by three factors:
A. The subject is located on a busy street and suffers external noise/traffic influence.
I was able to match the subject's street with two sales on the same street and one sale near a freeway with some (inferior- not similar) noise influence.
B. The subject has been significantly upgraded.
The subject's condition is above average and it has good upgrades. I was able to match this condition with one of the comps.
C. The subject has had an addition that appears to have been a result of the original garage conversion.
This creates a larger home with no garage among similar original models with a garage amenity.
I was able to bracket the subject's GLA and bracket the subject's lack of garage parking amenity.
I then discussed 2 sales I looked at but didn't use, and finally added this:
Although the subject matches homes of GLA that sell at a higher price, the subject's immediate neighborhood, original model, and street influence was a significant consideration in value. Other than the larger homes located in the City of Santa Clara, I found no homes that sold for more than $700k on XX street in the subject's San Jose area.
My final value is supported by the bracketed and unbracketed sales prices of the comps: It is valued higher than the same street sales as it is superior in GLA and condition, and is valued less than the non-same street sales due its inferior location. The valuation is consistent with the market and the comps.
The point being that now if someone reads the report, I hope they will understand my process and why what may appear to be comps worth consideration on paper are not worth consideration.
Also, I feel that by taking the explanation to this level, it does provide the reader/reviewer with a higher level of confidence that I have completed my due diligence and adds to the credibility of the report.
Obviously I'm not saying all reports need to go to this level of detail; some may need more. The point is that summarizing the process can be as easy an exercise as I completed, which took less than 10 additional minutes.
