Mold from a home inspector?

[Lacy Tilley]

Hello BP members! I have found my self in a pickle...i think? Selling my first house listed every thing went well buyer and i agreed on sale price. Now the home inspection.......

Purchase agreement stated Home inspection , mold inspection and radon inspection.

Buy had a home inspection (not mold?). Inspector stated

"Potential mold growth noted to the attic sheathing but cause is unknown.

Recommend a qualified mold contractor further evaluate and treat as needed to reduce further

growth, related damage and possible health concerns."

My "non professional" opinion is just staining of 50 year old wood there is no fuzzy mold.  

Buyer requested  remediation. I called around and inspections start at 150 for them to just look at this.  Im not sure how i can remediate something that isn't fact

My question is since the buyer agreed to inspections at there own expense should they cover this expense? Im also on a deadline for counter offering. 

My view is buy should have professional mold inspection vs home inspector speculating and hurting the chances of me selling my house.

Any Input would be greatly appreciated.
