Well, I can tell none of you are from Michigan (I know, you can't tell I'm from Michigan either - sorry, just have a problem with giving my location so freely, hubby's a truck driver).
Round here, a 6' high ceiling in a basement is typical, called "michigan" basements. Partial basements, cold storage, furnace, etc are kept there. I have even seen them with plastered ceilings (little Keebler elfs must have come around to do the job). I usually refer to this as a cellar in my reports cuz I know you have no idea what "Michigan" under basement description means, although you will see it on MLS sheets a lot!
Watch out for that functional obsolescence, Debra. And watch out what you read in your book regarding it, do not take the book word for word.
Remember, everything in the appraisal world is based on market reaction. What would a typical buyer in the market consider deficient? The book will detail how a 4 bedroom house with only 1 bathroom has functional obsolescence, or how a kitchen placed near the sleeping quarters will be functional obsolescence. If houses with 4 bedrooms and 1 bath are selling at a comparative $ amount to 4 bedrooms with 2 baths, there is no obsolescence, just a market reaction to the "extra" bathroom. However, if you see 4 bedroom 1 bath houses are selling for considerably lower, then you have the beginnings of an investigation into functional obsolescence. I need to put that word in some sort of a list on my computer so I don't have to type in anymore. LOL
