Roof was done 10 years ago but there were some leaks identified so inspector recommended that I change the roof.

The seller and inspector are making it seem like an easy fix/no big deal. 

The mold spore count is very low according to my inspector.

The sellers need to perform an inspection prior to listing and have it available, the inspector must fill out the seller's disclosure form with the sellers to the best of their knowledge.

This is exactly the kind of thing city building inspectors live for.

To fix these types of things in some geographic areas may require fixing a lot of other less important things -- know the local building inspector's expectations.

He agree with me and the City holding the money, 'hostage' and he mentioned to call and talk to the building inspector and perhaps get a lawyer to send a letter to the City.Yesterday, the City building inspector called and said the same thing as the previous City representative, along with that the Form is for the tax payers not to pay for a demolition of a property.

Hire an inspector to review the property in-depth.

What repairs have been recently made according to your inspector?
