The second thing is to have the property inspected to identify any problems and identify life expectancy of major components.  

@Charlie MacPherson  Heat pumps usually have electric resistance components in them for temps below 20-30 degrees. 

I have learned feeling the breeze is much more enjoyable than being a component of it.

You will need to learn all of these components of a development deal: land acquisition, site selection and sourcing, zoning and entitlements, architectural design management, deal underwriting, financing, construction, leasing, property management, and sale or asset management.

Rather you should go with a component valuation.

Re "apply for the mortgage together": as a beginner, you are confusing terminology a bit here, so let's break it down into the various parts.People apply for a "loan secured by real estate", and refer to that as "applying for a mortgage", but that is not following the strictest definitions of the terms.A "loan secured by real estate" consists of two components: a promissory note, and a security instrument that pledges the real estate as collateral to secure the loan.

This is a pretty thorough description of the standard design process Design-Bid-Build: http://blog.buildllc.com/2008/09/the-process-of-ar...Fast track design is an expedited process and generally there are phases, like foundation scope, which start construction while other components are still in design.

Also google “your county or town name and real property” you should be able to pull up the county or town tax records and hopefully they have a search component and you can bring up other nearby duplex properties to see if they are also similarly assessed.

You need to check with the Park to make sure they will let you sublet it - many will not and require owner occupancy.I personally would not want to be responsible for mobile home repairs, which you can expect will be often as the components are typically cheaper than stick built.  

Oh yeah, I do this because I do not want a contractor/handyman to supply poor quality components that they will be installing.
