Exactly right. Even then though, it's a crap-shoot with renters. Personally, I would never do it again. One, just one, really good renter we had out of maybe 5-6, in a duplex years ago.
Good to see ya, Toastedturningtidelegs. 
Me too ! I love talking about the tide is turning. This has legs. This/that/he/her/it is toast !
As for renters...
Don't rent to Indians...you'll never get the curry smell out.
Don't rent to Italians...you'll never get the garlic smell out.
Don't rent to Jews...for obvious reasons.
Don't rent to Jamaicans...you'll never get the gange smell out.
Don't rent to Indians...you'll never get the tax free tobacco smell out.
Don't rent to Cubans...you'll never get the plantain smell out.
Don't rent to Single guys...you'll never get that new girlfriend smell
The same applies to single women, lesbians and homo's. They all leave that new girl/boyfriend smell
Never rent to the Irish...you'll never get rid of that whiskey smell.
Never rent to the Russians...you'll never get rid of that vodka smell. It's barely perceptible to the less sensitive, but it's there.
Never rent to the Mexicans...you'll have tequilla worms everywhere.
This is by no means an all inclusive list.
There are many many others you never want to rent to.
Anyone is free to add suggestions to the no rent list !
