Home inspectors see many instances of deferred maintenance when inspecting the average home. The newer the house, usually the less of that the inspector sees. We might note oversights and deficiencies that will lead to problems over time, but usually not deterioration at a new house.
At a property that has had time to develop some problems, failed caulking and paint is a commonly seen issue. The photo below is a laminate or plywood siding. Where the hole plug was put into the plywood at the factory, the failed finish is allowing moisture into the material.
In this instance, maintenance was neglected for several years. Decay and de-lamination are present. Furthermore, basic installation of siding and horizontal transitions, lack of proper flashings, has exacerbated the problem. In the long run, neglecting a property will be more costly when repairing, or selling the house, than a conscientious program of diligent home maintenance.
