OK, no I go with my original response, but let’s work through it, we have time.
1. Do not consider the drive way.
Before the repair when the drive way existed, and when it was first installed, did it add value to the property?
If this were appraised, the drive way should have added value to the property when it was first built. (Can we agree?)
A number of years pass, and the driveway is deteriorating, but useful it needs some repair, maybe it can go another year, but I want to repair it this year.
Generally, if the property were appraised on the day before you repaired it. The appraiser would not have discounted the value of the property. Most appraisals, unless the driveway were in such disrepair as to be useless, would not discount the appraisal. The question would be, does it have a paved drive way, yes or no.
So in all likely hood, the entire house and property were not depreciated because of the condition of the drive way. (Can we agree on this?)
Now comes the repair, did making a resurface increase the appraised value of the property or did it just make it look better, prettier, more aesthetic looking? My guess is, that unless that drive way was unusable, it did not increase the appraisal value of the home or land. (Can we agree on this?)
Then I would say this is like painting a house. There was no added value, even though it looked nicer and might be easier to market and sell.
While the depreciable life of the drive way is a 35 year property, in the construction industry, black top or asphalt slab is a 100 year life property. When you were done, it was still a 100 year property. The life of the integral whole was not necessarily extended.
