Common contingencies are inspection, financing and appraisal.

But the inspection reports didn't suggest any driveway repair. 

It allows you as a buyer to do an inspection, appraisal, etc. 

Any earnest money or expenses such as inspections may not be paid by you or a disqualified person to your IRA.It typically takes 3-4 weeks to setup a plan, and that is assuming you have the ability to request a rollover early in the process. 

I don’t see how inspection permits can be deal killers.

Now if you inspect the property/bring the broker out there with no way of closing, then you're a tire kicker. 

I notice at purchase you have $1800 closing but show no loan so assuming hard or private money, or cash and $1800 goes to inspection and title work?  

The consultant needs to (1) do a site inspection and (2) review a government database search. old reports may or may not be available depending if the seller or property owner provides one.  

You can look at their true costs, the condition of the park for Capex needs, the reservations that happen, leases that may exist, get inspections - I'm sure you know all this.  

Otherwise, it's hard to manage sub-contractors, inspections, and the Residents themselves when you aren't local and able to physically be there.
