Good point on the PPSF being reduced as it doesn’t include land and entitlement costs. That makes sense.
Like henry, we were worried that they would use the actual, and full, cost of the improvements to reassess. They didn’t do that, though it was close enough. Of course, the money we spent would probably increase the value of the property to a greater degree than landscaping, dollar-for-dollar, which is why I thought he should call to clarify (like you suggested, as well).
