Rent relationship of mobile homes to other homes

[James Mc Ree]

I recently took an interest in researching mobile homes.  I am looking at "not new" homes and feel I am missing something.  Here is an example to illustrate.

There are several 3 bedroom, 1 or 2 bath mobile homes in the county listed for $20,000 or so that appear in good condition.  The surrounding area has 3 bedroom townhouses of approximately the same sqft renting for $1,200/month.  Does a 3/1 mobile home rent for about the same as a 3/1 townhouse in the same area?  I realize there are a bunch of qualifications to anyone's answer, such as "depends on condition, area, etc."  I am just trying to get a feel for what to expect in general for mobile home rents compared to brick and mortar real estate.

thanks, Jim.
