I go through the count records and ask about Sf, age, garage SF (how many bays), lot size, have they done any remodeling, has the house been for sale in the past 12 months (FSBO i check MLS), HOA information, siding, roofing, windows, floor covering, windows dbl pn, sngl pn, and materials of windows alm/vinyl/wood, fencing, outbuildings, view if any, wtf if any, and anything else that they can think of.
Then I tell them what I will be doing there measure the outside first take front rear photos and 3 int. photos, look in all rooms and closests, and will have more questions for them at the time of inspection.
And that the inspection will take approx XX-XX amount of time depending on the type of house.
I also pull comps prior to inspection. My parameters are typically pretty wide plat 12 months, 1 mile around the subject for 6-12 months depending on area (urban to suburban settings 6 months and suburban to rural settings 12 months) then a neighborhood search for again depending 6-12 months. Then I pull a CMA for the subject including active, pending, and solds. From there I may chose several that appear to fit the subject on paper and pull full printouts on them and MLS information. I figure with this amount of information it is hard to really miss anything and if I do go out and it doesn't fit any of the properties that I have then I may have something in the initial research. Typically 1-2 times a month I may find myself looking again because of something that wasn't disclosed in the phone interview or something was different.
