You miss out on a lot of modern advancements. A few things that come to mind from my lovely house: * Single pane windows that leak heat / cool, also that rattle. * Lack of insulation. * Non-grounded wiring / unsafe wiring. * Plaster instead of drywall, cracks very easily. * Old heating systems (oil furnace with steam radiators). * Crooked doorways and doors that don't close quite right.
