This is common practice across the US and the rule-of-thumb 40x generally tries to take most cases into account. i.e., 40x after taxes and other typical debt levels is "risk appropriate" for landlords... Though don't get me started on how this reduces landlord risk to a level where they should not see profits... It does seem odd though when you consider one person with 40x may have a completely different net than another.
