Very motivated Seller, very weird tenant

[Kirby Jackson]

I met with a very motivated seller yesterday.  a 1 bedroom each side duplex,  the current tenant has been there for 10 years and never had a late payment.   but when we agreed to meet and for her to show us the property, she would not let the owner in.  after about 30 minutes of waiting out side while the owner texted back and forth with the tenant, she finally agreed to let us in.  we only got in as far as the living room/kitchen, and were told we could not go into the bedroom/bathroom because the dog was in there.  but the dog only barked like twice since we were there, hardly menacing.  

what do you do in this situation? are their buyers out their that will purchase the property and leave the tenant in place.  I guess the tenant has done some of the upgrades with her own money, and apparently the seller and Tenant normally have a great relationship, but not yesterday.  it wasn't hostile at all, just non responsive.  I think the tenant just hoped that we would just go away.

So there are PROs and CONs to this situation.  I have a very nice and motivated seller, but I have difficulties with seeing the property since the tenant is being non-responsive.

thanks
