It is an excellent way to go. In 1999 we researched the whole housing thing very carefully. In our area stick built houses are built for $300-900 per sq ft.
We have a 2200 sq ft home 4 bed two bath, R 40 ceiling and floor, R33 wallsm meets our snowload requirement of 120 lbs per sq ft installed on a permanent foundation for $85 per square foot.
We now have plans to relocate to a smaller home on the coast, which we will install on our property, that too will be a manufactured home, this will cost about $100 per sq ft. plus installation.
A final note, we looked at lots of manufacturers, the only one we felt built a quality home was Fuqua out of Bend Oregon, the home we live in and the home we are moving to are Fuquas. You can see a photo of our current manufactured home at

I am just now creating the website for the sale, It won't be on the market until late Spring, we have painting and fixing up yet to do, and it is -5 outside, not good painting weather. Some of the photos are just placeholder photos, but you can get an idea of what a quality manufacture home looks like.
Some things to consider, if you get a rectangular floor plan it looks like a double wide box. Consider floor plans which create angles when seen from the outside. T-111 looks fake, most homes even stick built seem to use it, if you do, use the board and batt style, looks less fake, better yet use real wood, our home is ship lap, you can also get fake log which looks good on a rural parcel.
Most M homes are set above ground as on a slab foundation, which gives a distinctive manufactured home look with steps, you can also set at ground level which gives a stickbuilt look.
