A tenant asked if they could adopt a pet; when I replied with the information regarding deposit and pet rent, I never heard back until I followed up today (3 weeks later), making sure they saw my email, and reminding them that having an unauthorized pet would be a violation of their lease agreement.

They moved early so I've been trying to re-lease and refund them part of their lease if we get a new tenant before year end - just to help with the baby expenses.Also, I don't allow pets - bad experiences with another rental in the past.

She has a pet so she is looking for a small house.

MF gets a lot of complaints about noise, odors, smoking/pet violations, parking issues, someone not cleaning up after themselves in the laundry room, etc.There are benefits to each and it depends on whether you are looking at it from the view of cash-flow or work-load.

Pets are not allowed by the lease. 

If your tenants don't behave you can get fined and have trouble...putting trash out on the wrong day, putting stuff on the balcony, disturbing the neighbors, parking in the wrong spots, some condos don't allow tenants to have pets, some tenants don't clean up after pets, and on and on and on when you get tenants residing a 2x4 away from the neighbor.   

Was really excited about the landlord forms.....mostly because i have a tenant wanting to add a pet.

read on a flooring forum somewhere that a guy puts Tyvek house wrap on top of the hardwood and below the carpet padding. this way, if a pet pees, it would never hit the hardwood floor.i had a chance to do it on the newest house, but the carpet guy said it would be "overkill, since you have the best pad already". but i will do it from now on just for the extra protection.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.
