I was already planning to go to that and then one of the local real estate agents that are here on BP invited me also. 

Matt,Invitation is open to you as well.  

That offer is an open invitation for all.  

There is no shame in letting them know that the property is again available and that you invite them to apply.

Either way, we do another open house, a week later, in the same neighborhood but different house, and invite new and the old bad/good credit people.

I am also wondering if we invite him inside our house and studio, maybe he can find other issues that can be used against us etc?

We will see, I need to do a lot more research before I jump in.And thanks for the invite to the meet up Jonathan M., I will definitely look into possibly attending if not this one then one in the near future.

I received an invite to attend an REI meet-up in Colorado Springs.  

A guarantee to lower the price is simply an invitation to raise the price as high as a seller can, with or without adding any value, and gamble on an appraiser bringing in as high a value as possible.  

And use a invitation sized envelope.
