I am decidedly naive of some home ownership details. I rented into my 50's as a possible mistaken financial strategy, but in the end enjoyed the freedom for the time. My home was build in the 1950's and has wooden siding. Eight or so years ago I scaped, sanded and brush painted the siding and in the end I said, I'll never do that again. Now, sometime in the next year, a little sooner or later, I will need to pay someone to paint or will need to get some sort of new manufactured siding.
There are obvious immediate out of pocket costs, but in the list of pros and cons the top things I see in the siding pros are less maintenance and increase in home value. I'm not sure if there are any environmental differences. Based on my actuarial age and the probability of being able to maintain a home, I'm thinking maybe a ten to fifteen year time line of living at the same place. My informal survey of neighbors and neighborhood says that wood siding on frame houses is a thing of the past? Plastics.
