Insult is the highest form of flattery Shaker.
WAL is actually a renter (i.e. It's the Dogs House, they just pay the rent). No problem finding a place to rent with dog and two cats. I think you have a better chance if the Landlord is a pet owner. Pets actually do not do damage, I've said it before, its the kids you have to worry about.
My landlord came to set up our alarm and set it so that the dog can stay inside while the alarm is on. I even asked him to let her out for a pee and then let her back in again while I was at work. The cheek of tenants today, I don't know.
My tenants in Oz got themselves a puppy and a kitten without asking. Discovered when my managing agents went for the 3 month inspection. I don't care though, it tells me that they are settling in for a while. Just renewed for their 2nd year. They have two kids too. Oh dear, good thing I'm 12,000 miles away!
I have something called 'Landlord Insurance' though. Probably a new concept to the amateur BTL'ers
The only reference I found in a few seconds was from 2001 though. Has the law or the interpretation of the law changed?
Though, perhaps "having to deal with unreasonable terms in contracts and the conflict they can cause" would be another con for the wiki.
I see loads of places that say "no pets, no kids".
Unreasonable withholding of deposit.
