In other words, if a longtime owner in their sixties wants to sell their suburban homestead now, they are not as interested in recovering their investment of a pool they installed in ’86 that their five kids (all grown now) had weekly pool parties in. It’s old and used now and sellers realize that many buyers with young children don’t want pools.
OTOH, if these same owners installed $14K of “Low E” vinyl windows just three years ago, they will want to recoup that investment on sale.
