So, I don't think frozen pipes were a concern.

It would mean the world to me if you leave us a great review.

I'm more concerned on if it's going to be a good deal or not.

If they are leaving mid-Feb and willing to pay 6 weeks' rent to break the lease, that is reasonable. 

I've had qualified renters move into a rental, add their bum friends or family members, and then disappear, leaving me with bad renters who weren't approved and aren't on the lease.The best practice is to screen every adult, approve them, and add them to the lease. 

I am concerned that your investment outlook isin't patient enough.

They'll typically leave behind mattresses, couches, broken furniture, rotten food, etc.

You are excluding possibly the majority of available tenants to focus on the most difficult to manage and the ones who are most likely to leave your property heavily worn and damaged, all other things being equal.

It seems like anyone can post anything without accountability—very concerning.  

A quote with no cost breakdown can definitely be a red flag—it makes it harder to understand what you’re paying for and leaves room for unexpected costs to pop up.
