> What part of "age/deterioration" makes units lose value, exactly? Is it just that buildings aren't built to last, or is it that newer buildings have newer amenities? My place is (San Francisco) affordable, but: - 2 people have been shot & killed on my block in the last year - there's regularly poop on the sidewalk in front of my building - one of the two elevators in my building is often out of service (and occasionally it's both!) - my apartment has no kitchen - the plumbing is old (aka leaks) - the door to my bathroom doesn't quite close - the paint is peeling in some noticeable places - some places in the common areas never get dusted - random people walk in and steal packages from time to time - there's no air conditioner (don't really need it tough) - the heater barely works (don't really need it tough) - the electrical outlets are in funny places - the main window never stays open quite all the way - there are small gaps under the fake hardwood flooring - my bathtub looks like it was attacked by a 5 year old with a sharpie It's nice a primo place. Don't get me wrong, I love where I live. But I wouldn't pay primo prices for it. I'm just talking about "age/deterioration", since you asked.
