Who should pay for septic pump out during Inspections?

[Dave Carella]

I'm currently under short sale contract, but no earnest money has been exchanged. I just got a quote from a septic service . The inspections would be 175 and If needed...... a additional 300 to do a pump out in order to inspect it. So I may be looking at 475 just to do the inspection???? Hell no. I think the seller should pay for the pump out if it needs it. I know your probably gonna say put a amendment in the contract, but ive been working on this deal for 2 months now. 

what's the standard on this? 

Thanks all!
