Broker In Charge From Hell?

[Ryan M Corder]

So the title might be a little extreme, but this is our first go at this and aren't sure. 

We are supposed to close on our first flip tomorrow!  It is a townhouse we bought at the courthouse and luckily the rehab was just some drywall work, new floors, paint, appliance, and countertops.  The buyers inspectors literally praised the work we had done throughout, but a week ago the CL-100 wood infestation inspection came back noting a small bit of non-structural exterior sheathing damage along the bottom of the back wall behind the vinyl siding due to moisture :( 

The good news is we are 99.9% sure the issue was caused by rain water coming off of the roof and landing in an area that had standing water before we brought in some dirt and gravel to resolve the drainage issue during the remodel (townhouse is on a slab).  The Cl-100 report also noted there was no active issues (ie. growing model or rot) and the moisture content in the wood was normal. So we filed a maintenance request with the HOA and called them. During the call the HOA confirmed that they would be responsible for exterior sheathing repairs if it was deemed necessary and caused by exterior water. 

We informed the buyers agent of the above, and to make a long story short, the buyer's broker is now demanding (not so nicely) that we pay to fix the sheathing ourselves before closing!  On top of that, the broker has called our CL-100 inspector this morning and apparently yelled at him and called him not so nice names. 

Every experienced real estate person we have spoken to has confirmed that the buyer should move forward with the sale the way things stand. 

However I thought I would post here to to document this experience for anyone else who might find themselves in this situation and to ask are we the crazy ones for standing our ground or is this the broker in charge from hell?
