I bought a 2006 Timberland used in 2012. It was very well constructed, with plywood floor (not OSB), real wood stringers (floor supports), not the newer cheapie OSB I-beam stringers. Good quality windows; good cabinets; good roof; hardi-plank siding; and, unlike manufactured, it actually had an attic you could enter for service. Overall, it was well built. Unfortunately, when they delivered the home, the contractor who did the poured-in-place foundation left one corner low, so that corner of the house was not level. To make up to the damage to the corner drywall from the slight drop, they pumped in a lot of chalking floor to ceiling. It was not a conventional drywall repair and was not appropriate; but I lived with it because the paint covered it decently well. I would buy another Timberland home, but when I called them to do just that for a lot I had, I found their prices to be as high as an on-site builder, so in that case why bother with modular, which is rated as stick built by building departments but which I find carry a certain at least slight stigma, no matter how well they are built. This is written in 2018, and housing prices have gone up and away from my budget, so I started looking at manufactured. I have been very disappointed in what I have seen. Mostly they use cheap materials, are not well assembled, and go down hill much faster than stick built. No matter what you read, take my word for it that OSB is a second rate material, no matter what the grade, although everyone uses it even on high-end (expensive) stick-builts. On roofs, it does not hold roofing nails as well as plywood. It is prone to come apart if it gets wet, no matter where it is placed, on walls, floors, or roofs. OSB is not particle board, but it is still just a mountain of little scraps of wood pressed and glued together. Too bad home builders have so little pride when it comes to this product. It is only suited for sheds.
