Is so - what are the chances to get permits to build and what would you estimate the cost to actually get the land ready to build (water delineation, mitigation etc..)?

If you can afford it, I would recommend a Triplex or even a 4 unit; because you are mitigating your risk and likely increasing your cash flow.

Are they experienced in the loss mitigation requirements?

When I compared prices with other vendors seemed to be quite reasonable ($399).One of my bigger concerns about hitting then "Pay" button was whether this company will be there for me in the event that their report ever gets questioned by the "authorities", you know who I am referring to :).To mitigate that risk I looked up individuals on their site and made some calls.

@Carlos C. in our opinion, the only real reason to put your properties in an LLC is for anonymity.Many investors screw this up though, by using their own name and address as the LLC Registered Agent:(All risk can be mitigated with enough insurance. 

Enough to get you close but mitigate a turnover if possible.My biggest advice is be brutally honest when you assess market rate.

That should mitigate any liability claim relating to the issue.

How do you mitigate it?

That region will require some risk mitigation, and would be better suited for a local flipper specializing in those types of properties vs buy and hold OOS IMO. 

Most DSTs have a disposition fee on the back end that they only receive after they've returned original capital, giving them an incentive to do so.Work with a group that has experience with the sponsors and knows what potential red flags to look for in each offering so you might mitigate potential risks.
