If you have 400 recent sales in a tract home development are you going to narrow them down any? Or set about analyzing each one of their features and characteristics? Do you analyze each of the teardowns and REO properties? Or do you look those over and immediately disqualify them due to their sales price?
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.
