QUOTE Slow down everyone..... it`s a dog, not a cheetah.
No kidding! If the little mutt damages the property, pay for it with their damage deposit. As long as you`re reasonable, you win. And, given that this looks to be a single mother, she`ll probably treat that hound like it`s friggin` sent from heaven. I`ve seen it before. I know a few girls who consider their dog their "kid". Crazy, yes, but it`s out there.
If people want to strap themselves to a 10 - 14 year commitment with some slobbering, foul-smelling, fur-shedding, messy, annoying, crap-happy creature like a dog, that`s their choice. As the landlord, one thing should be of utmost importance to you, and that`s the rent cheque clearing on a monthly basis. In actuality, this new "dog" just makes them that much more tied to you, as it probably costs them about $100/mo. to feed the thing, meaning that she`s that much more loyal/committed to her income stream (job), meaning that she`s probably not going to be buying a place anytime soon, meaning that she`s probably happy where she is and has no plans on leaving.
Congratulations, sounds like a homerun for you.
