We have had a Strctural Engineer out to the property and while we don't need to conduct repairs within the next 5 years or so, we will need to address both of these things at some point and it will likely cost us about 100k.Any advice on selling or holding for the long term?

To clarify this, you may need to conduct a thorough physical inspection or hire a professional appraiser or contractor to measure both levels separately.
