Remodel Vs. Replacement

[Dave C.]

I have a 1975 Marlette Singlewide that needs about $10,000 in repairs( ie. floors, mold remediation, various other issues). It's on its own lot( not in a park) with city water and sewer.

I'm leaning towards removing or demolishing the existing trailer and replacing it with a 1990 or newer singlewide . I'm thinking I can pick something like this for around $5k to $8k. I'm thinking transport fees would run about $2k. 

Are there any other potential hidden costs I should factor in for deciding between remodeling versus replacement?
