Problem was that they were being sold at more,than a competing brick home to people with no credit for no money down.
Then many that have been sold are low cost, with a probable life expectancy of 30-40 years max vs a probable life of 100 years for a typical residence. But they are still being marketed as having a similar life.
And finally, few are on owned lots, so financing is very difficult.
MHs have been touted as the answer for decades. Still not the answer.
Its mass manufacture brought to the home.
When you can do this, you can lower prices and increase quality.
You have to shop around for the best deal.
I never sold one in Southern Mississippi that was headed for a park. They were all going on to privately owned land.
