especially now where in all likelihood you are going to overpay for the property, and at anytime the government just decides that your tenants can stop paying rent for a year or more, but you still need to make your mortgage payments, property tax payments and keep insurance and the heat on etc.
Some people do well with rental properties over the long haul, I wouldn't touch it with a ten foot pool these days - especially if you live in a state where tenants have more rights than the owners of the property.
