Just one last update, after being extremely frustrated I decided to send one last email to listing agent . Laying down importance of gaining access to property . Also saying I will be reporting you to this that and the other . (3 days ago ). I gave him 24hrs to respond or I will be forced to proceed with actions, that night I received 3 emails, who is your listing agent, I'll send codes right away, also sent codes to title company. Also would like to discuss your threats. My response there are no threats, I just want to close deal and you can disregard all statements . So after he gives codes, next day my agent goes to property no lock box and property is completely secured , He has contacted listing agent and will be sending a maintenance person today for assistance with new lockbox. Frustrating ordeal but looks like we are going to close this deal. (Out a 1000$ early incentive closing bonus, lesson learnt I will never do business with him again ). No matter how good of a deal.
