Can we negotiate on damage we don't see?

Yes — if it’s discovered during the inspection/due diligence period. You can negotiate repairs, credits, or price reductions based on what the inspection reveals.

In most situations, you can not negotiate for what you think might be an issue in the future. In most states including SC You are given a Due Diligence period to do inspections. a good home inspector might be able to do a moisture read on the area to determine if there are high moisture readings. Express your concerns with the inspector and see if they may be able to give you more details of any issues. and then have your REALTOR relay those concerns based on the inspections to the selling agent and the sellers. Then go from there based on the recommendations of the inspector and the REALTOR representing your side of the process.

Here in MN, anytime someone lists their property they need to fill out a Sellers Disclosure Form, they can either fill out the disclosure statement form OR the disclosures alternatives form. If they fill out the disclosure statement form, they need to mark on it any damage that has happened to the property that they are aware of. even if it was fixed. Another good thing to have done when buying a home is to get an inspection through a trusted company and mention your concerns before they go out there to inspect the home. You can always re-negotiate after the inspection is done.

I would recommed to get a home inspection by a liv=censed professional.

There is a moisture reader; if their evidence of moisture, then I could recommend having a professional pull up the carpet to see if there is mold and where the moisture is coming from
