I say you are not even the tail of the dog but a flea on the tail of the dog. 

Do they have a FB page with their dogs and say they don't have pets. is it all about partying.     

When I listed concerns of flagrant lease violations, gone unchecked (derelict vehicles, unregistered large breed dogs who are not picked up after, garbage scattered out in the yard, piles of debris; old tires, tv, kitchen sink, broken wheel barrow, all sitting out in plain sight for a month or more), wash machine drain hose running out a window and draining into the lawn.

I say that because the primer to cover the water stain may have to have your renters And their pets out of the unit for so many hours while they do it and then it dries because it may gas off.

But the reality may be that the tenant hasn't paid in two months, or pays 20 days late every month, or their dog is destroying the carpet, etc.There are literally hundreds of threads explaining the dangers of buying a property with existing renters.

Hey @Dipika Mulchandani, I don't have a dog in this fight, but there is a constant stream of articles about lack of LTRs in that area.

Hello Every,I am currently in the process of buying a property and was told by the selling agent that the current tenant has violated their current lease by having pets and not putting down a deposit.

Also find out if they have a move out list for you to check and what the expectations are (ie I expect any carpet to be professionally cleaned and want a receipt, over is cleaned, if you had a pet any poop in the yard to be picked up, etc).  

I try to compare amenities,  but these houses don't have their own pools, most don't allow pets,  and they don't look that much better renovated.

Consider 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.
