They can't let the animal annoy the neighbors by barking all day, urinate on the walls, or chew up the window sills.

That's a lot more to chew on than most non-locals want to deal with, but for those of us here, there are good opportunities to be had.

There is a lot to chew on.

The fact other properties have chewed up sidewalk isn't a sound legal argument either.

For your first one don't bite off more then you can chew.

Oh, and the boyfriend apparently brought in a large dog that scratched up all the doors, chewed up some window sills, dug up carpet in the bedroom they kept it in, and crapped all over the new carpet.

However will I be biting off more than I chew with this one? 

It's easy to bite off more than you can chew in this business and that's especially not a good idea for your first deal.

Quote from @Leeling Chew: Documentation probably isn't that big of a deal.

I have not lived in the property two years and feel that any profit I may make on a sale would get chewed up by closing costs and capital gains.
