You should absolutely pay.Realtors have a large variety of responsibilities and motives, and the good ones will provide a lot of GREAT service for you, but this is quite the stretch.

@Wayne Brooks Thanks for the response.

Allowing it to continue for years with no response is going to make things really bad. 

@Chris Tracy Thanks for the response.

Thanks for your response Aaron Klatt.

Typically what he provides is a letter stating the property has been sold and here are the new instructions to contact for maintenance issues and instructions for payment (also provides a copy of the deed, showing the sale). 

Thank you @Alex Deacon for the response and I agree that I am not ready for this type of investment strategy, but I wanted to attend to at least have a better understanding of the process. 

As already stated you have fulfilled your responsibilities, Take one or two space heaters and do not give a rent rebate...sets a bad precedent and not required under the circumstances.

If you're in a multiple story condo, check the bylaws to see if you are responsible for water damage to any units below yours.Pay close attention to warranties.

@Brandon CraigHi Brandon I'm going to be the first response here and the 'wet noodle' of sorts.Firstly, get your credit working for you.
