Looking for assistance with due dilligence north of Atlanta GA - Retail + Office expertise

[Ben Bakhshi]

We are going to potentially make an offer on retail and office opportunity that is over 50% vacant. We will do some of our own due diligence, but are looking for further assistance to make sure that we end up with a smart buy.

Can I get any recommendations for companies or service providers that are great with doing due diligence on these purchases? Including rent research, market research, etc.
