What the heck kind of fantasy assignment is that?
Man, I could kick 10 a week with those kinds of developments. For my 'typical' assignment, I am thankful to get 3-5 good recent sales with characteristics as similar as possible to subject (the definition of comparable you were seeking, BTW
) without having to search beyond 6 months or 1 mile.
If I do get that dream assignment where there are too many potential comps, I will zero in on these items, in this order: (time, distance, GLA, and if needed, BR/BA count, garage spaces, current condition--more a manual one by one look). By this point, price has taken care of itself, other than perhaps the outliers that are in C5 or come with 4 extra buildable lots. I like the =/- two std dev rule. If there are still too many, than I will zoom in again--at that point I am probably looking for model matches on the same street that sold last week. Again, with a search that tight, price will be taking care of itself.
I understand what you are saying about narrowing search parameters, we all have a rough idea what properties are valued at in our markets, but I think searching BY price is usually not necessary. This has helped me sometimes because I like to examine outliers and see why they are...outliers. I feel like I need to understand those strange sales in my market. I wouldnt see the outliers if I searched by price alone, or first.
