A sizable percentage of people don't want to live in condos. And they aren't necessarily small, either.
>This do increase the price of real estate, but not that much relative to the bigger picture. The price of a "glitzy" fridge vs. a non glitzy fridge is going to be what, $500? $1,000?
That's an extreme understatement. A glitzy refrigerator might only had $500 but marble counters might add $20,000 or more. Same with flooring. The price difference on a house full of stick on vinyl and real hard wood might be an additional $20,000. Then you get to other cosmetics such as crown moldings, jacuzzi tubs, walk in showers, vaulted ceilings, heated towel racks, and more. You could take the exact same house structure, and through flooring, counters, and cosmetics alone you could easily jack the cost up by $60,000.
>Likewise, appreciation has occurred on older properties without these features
Not really. Houses get upgraded with better floorings, better counters, additions, and other renovations. Go find a house in your neighborhood built in the 1950s with no major additions, laminate counters, and cheap flooring. Good luck.
