I guess the first question to ask is if you are working with a Realtor. If you answer yes...then that is something that your real estate agent should have found out about for you. You have an inspection period and during that time you should have received a copy of the CCR's for the Homeowners Association. By reading the CCR's and By-Laws if applicable there should be a disclosure regarding no dogs allowed....most likely contained within the CCR's. The next question that I have...is if the listing of the property was in the Multiple Listing Service and if that disclosed the fact that no dogs are allowed. Unfortunately we do run into some cases where no pets are allowed unless they are assistance pets...and at times some properties do not even allow rentals. So it is important to find out about these things prior to making an offer on a property. You need to discuss this with your Realtor...and if you do not have a Realtor then if you do in fact get out of your current transaction you need to find a qualified real estate agent that can assist you with your real estate needs. I have been in business for over 27 years now...and one of the first things I do with my clients is to sit them down and discuss all their needs and wants regarding purchasing real estate property...so that situation like yours will not happen. If you need further assistance and are not working with a real estate agent...I would be pleased to assist you regarding finding the proper property for you. I hope things work out for you regarding your current problems.
