High end trim work, door knobs, light  fixtures can really add up.

What other major capital improvements need to be considered (e.g. roads, tree trimming, other infrastructure)?

A few weeks ago he requested some tree trimming, which we were planning to have done anyway.

But you will have to take a look at some of the items that might be effected by that: outlets, light switches, other trim like window trim, baseboards or crownmoldingOnce you open up the walls and a framing inspector sees that, they will make you bring things up to code.

Slate walks, window-filled 3-season room, lighted ceiling fans, polished wood trim.

The only real good deals I have seen actually work are these older buildings in the right neighborhoods that are structurally sound, and then restoring them to a Victorian/Edwardian feel but paying special attention to the detailing like molding and trim.

and if you can trim back that tree, you may have fewer leaves falling directly into it...could be the angle but it looks very close, almost overhead....they make all types of screens but I like to just clean them out and like see where it is clogged or filling up and how it flows That deciduous tree I would trim way back or even remove if a rental...best of luck 

With a  repair, I supposed it could be trimmed out and covered as there are no windows on this end of the house.

I purchased properties that did not need major work (clean, paint, refinish floors, one house the tenant took all the trim throughout the house...never figured that one out).

He also said that the market demands very high quality work, trim and appliances.
