Foundation recently repaired ?

[Ahmad D.]

Hey folks, I'm in the inspection period for a property and received the following feedback from the inspector. This was not "red flagged" but feedback to note:

"This foundation appears to have recent/past repairs. Consultation with the seller and/or seller's disclosure prior to property purchase is advised."

Foundation is concrete slab. I don't have photos but I can probably call to get more details. 

Have you run into this before and is it a red flag ? What would be good details to find out ?

Note that seller's disclosures don't have much information, mostly in the Don't Know/Unknown category
