My wife and I have owned rental properties before and we still currently own her old condo that we rent out. The notion that you should expect to change the carpet and paint every time a new tenant comes in is quite a stretch. If you have quality tenants, you shouldn't have to repaint rooms in a house. The last three couples we've rented to, over a 6 year period, have been great tenants with no damage whatsoever to the property. We even gave them the option of repainting some of the rooms themselves if they wanted to but none did and we've never had to repaint them because of damage. Carpet and Hardwood floors in the condo are in great shape too.
So the notion that a guy who rents a big house should expect to have to do $60K worth of repairs after a tenant leaves is funny.
