Agreeing with K2 and DevilDog:
Real estate appraisers are looking for major amenities and features which they can find in common with known homes of similar characteristics that have sold in your area in a recent period of time.
They are not interested in details and things like insulated garage doors, types of gutters etc...These things won't even be considered for the most part.
What they will be comparing are the number of bedrooms, the size of a garage if any, number of bathrooms, type of siding, condition of roof, total square footage, size of lot, general age and condition of the kitchen, heat type/fuel/age of heat system, central AC, types and kinds of windows, insulation, fireplaces, type of flooring, etc...
Appraisers are only interested in the 'big things' and those they can compare practically to homes that have recently sold to get a fair market value for the home.
All a lender really wants to know is that they are not allowing you to mortgage more money to buy the house than what the house is worth.
They want to know in the event you default, that they can get their loan money back.
Maintenance items like a nice paint job and repaired gutters and shutters and other things will help make a nice impression on the appraiser, but will do little in determining what your house has in the way of amenties compared to other houses in your area.
Since appraisers can do on avergae of 6-10 appraisals in a day, he won't even 'see' the little things....
