MI homes 30 years ago when they were starting out made very good quality homes. MI "custom" homes are very good homes. MI mass building homes of the last decade are for the most part decent homes. However what I personally choose to spend my money on is not necessarily decent. I have been called out to fix many many issues on houses where sub contractors, and this is key, were used during the big housing boom to build these houses. I could take sub contractors who do terrible work and put them into a house that would pass inspections. 5 years later there may not be a problem. Quality work? Or as with most terrible sub contractors, the material quality has allowed for little issue. But that only lasts so long then things start popping up. Only know it looks like its a material issue when in fact the material was installed incorrectly. I have been on hundreds of MI homesites. Years ago I knew alot subs for all the homebuilders on a first name basis. It was a running joke with alot of guys what they could get away with and still get paid. I suggest buying a home utilizing the expertise of a quality home inspector, a knowledgable realtor who has your best interest in mind and by talking to as many neighbors as possible before buying. Make a day of it and ask people what they think. But theres no substitute for common sense. If it doesnt look or feel righ, chances are its not.
