Not everyone have the cash to buy an older property and upgrade it. You can’t roll the cost of upgrade into a loan like a new house.
Why do you HAVE to upgrade it NOW and make it look like something out of Martha Stewart? People are complete woosies. A 1960s or 1970s kitchen with a new stove, fridge, and dishwasher (under 2 grand) is just as functional as a modern one. Bathrooms: laying tile is cheap if there’s nasty old carpet there.
The whole “zOMG we must remodel now” thing is idiotic as long as the basic systems of the house are intact and functional.
