Please note, I am not giving any legal advice as I am not attorney. You may have to check with an attorney.
In general purchaser of a property (buyer) given time to inspect the property and back out, if they are not comfortable to proceed. That is the objective of inspection. There are times, after we purchased there are issues that were hidden that we could not find out before. We were stuck to fix it unfortunately that costs funds beyond our original budget.
Again, this is not legal advice of any sort.
