Being that these dogs you are hearing from within the unit, I would suggest looking elsewhere. Park Ridge has 109 condos on the MLS right now. You may even consider looking in other areas if it means you can find a place you like and live without the noise. If you are working with a Realtor, I'm sure they can find more properties that will suit your needs in this present market. You are going to be investing a lot of money in something and you will want to enjoy it!
You've hit on a very complex dilemna... you love the property - BUT. The dogs didn't start barking the day you looked at the condo - and they probably won't stop. You have to ask yourself some questions:
1. Is the barking that loud?
2. Can you live with it - because you really want this property.
3. Do you possibly want to start off on the wrong foot with your possibly new neighbor?
4. Even with the CC&R's, what would be the ramifications be if you made issue right out of the gate?
Let me tell you what I would do because this is a sticky situation. I would definitely bring it up with my realtor (you have one right?) and have my representative (my realtor) discuss the situation with management.... indicating the clients concerns in reference to the noise.... and that this could possibly be a deal breaker.
This should keep you out of the loop - and make it a smooth transition. If it has been a significant problem in the complex, your agent will be able to discern this from the conversation he/she has with the management company.
Thank you for asking such a great question - I hope that you can resolve this issue quietly and amicably. Good luck to you and best wishes for a smooth transition!
