There are many options depending on your specific situation to be evaluated: credit, income, liabilities, down payment, etc.   

@Jared FisherPotentially could be enough time - depends on the state and status of the foreclosure.

Most commercial lenders 99.99% require you to own and have operated a commercial business or 2-3 investment homes prior to a commercial loan of that size.

MTRs do well depending on the area and how close you are to hospitals (because of travel nurses, etc).

Banks are in the business to sell money.

These inspections should include electrical, plumbing, and septic/sewer contractors (to address the underground infrastructure) but also can include pool, home/building inspections, asphalt, and more, depending on the park.

Depending on where you want to buy there might be better loans than FHA, BBVA for example has a nice loan called HOME that has something like 3% down and no PMI, depending on your income and where you want to live.

I would recommend Mike right now, as he is battling liver cancer and could use any new business possible to help him out with his expenses.  

Furthermore, depending on which state the property is in, if its a deficiency state the lender can foreclose and pursue you for their losses after. 

Thereafter, I ended up renting to graduate students until the visiting scholars returned this past fall.I suspect whether you do better with Sabbatical Homes dot com or Furnished Finder depends upon the location of your unit.
