I recently purchased 10 acres that has a 2005 double wide MH on it.  

I've seen easements only 10'wide - there's a lot that won't fit through that hole. 

Price it high and you'll probably still get an array of (lower) offers.  

We also have a double-wide on the property that is in average condition built in early 2000's We imagine the land is worth 30k and the house as is maybe 30k (3b2b 1640SqFt))What we are seriously wondering is whether to flip the double-wide and sell as a package with land and for more than double its worth, or to flip the double-wide conservatively and concentrate on the possible rents instead over the long term.Ideally because of the location and how much the property prices are rising in the area we can renovate the double wide to look beautiful and sell as an idealic country home with deck/fencing and put 20k-30k into the flip and sell all for $150k +So our main question is is it worth investing so much into a double-wide flip coz the location/land is sought after?

If you don't have good ones, you'll lose out on a lot of leads.Price - Make sure you are priced competitively.Promotion - Get the word our far and wide, particularly on online sites.  

I agree we are facing a nation wide shortage and this will continue to put pressure on pricing but buying over priced existing for appreciation the not only way to go in those markets. 

It was more a question of why the widely disparate valuations.

If it's in Denver proper, I seriously doubt it unless the lot is less than 50 ft wide.

Do I:1. just include a wide best estimate (ie 20-60k and  show what the return would be for a number of different values.

We have a wide variety of properties from turnkey all the way to in desperate need of renovations.
