IMO, far more annoying is when these same people with no real knowledge or experience or expertise decide to hang up a virtual shingle and begin brokering notes, or as some gurus call it, “brokering cash flows”.

If shingled, make sure there are no missing shingles or deterioration on the top which may be addressed down the road.

And replacing the roof shingles & kitchen appliances.

I had an inspector go out and take a look at it during construction and he found MAJOR problems ranging from possible asbestos insulation being airborne, lead-based paint cracking, cracks in the foundation and crawl space, old knob and tube wiring, moisture and mold issues, roof shingles replacement, and loads of other issues.Rather than talking about them, I made a playlist of the inspection here: https://www.youtube.com/watch?

We started getting work done on the exterior like roof, windows, exterior paint, new doors, railing for the stairs… Some things are coming in below budget, and some over budget like the roof needed all new wood under the shingles.
