Most selling for around $230 psf.Most MH are selling for around $105 psf for an older model and yes that includes a 0.25 acre plot of land.So I'm hoping to do this full time as a replacement income from my forced retirement at age 65, but start part time now.On another note....since I'm over 59.5 yrs old, I believe I can take the money out of my 401K and do a ROBS (rollover business start up) 401K and use those funds to purchase land, MH and improvements. 

If your employer plan allows for in-service withdrawals you could make non-taxable rollovers from that plan to a checkbook-control IRA or Solo 401k from which you could invest in RE.
