I prefer to stay further from the coast and hopefully further from major storm/flooding events (potentially lower insurance costs).  

Whether that's mobile home parks or any other kind of commercially valuated endeavor is a matter of personal comfort and preference.

My goal for next year is scale and acquire at least 5 more properties (preferably multifamily).

When it comes to analyzing properties, I’ve developed a specific checklist to make sure the home fits both resident needs and operational goals:Square Footage: Ideally, at least 2,000 sq. ft. to ensure enough living space for residents and staff.No Stairs or Pools: It reduces liability and keeps the home accessible for everyone (this is just my preference).Corner Lots: I love corner lots because they often provide extra parking and outdoor space—both of which are critical for families and visitors.

Accountant – Preferably a CPA. 

If there's enough duplexes that it's likely you find one you like in a reasonable amount of time (less than a year), then start looking at them in your preferred area.

I’m Norwegian, I live in Dubai but I still prefer to invest in USA. 

Since the distributions are from a preferred return they are not guaranteed payments. 

The only drawback from this I see besides needing the cash to fund it, is for an investor who prefers to get all their cash invested back from a deal will more than likely not get everything back at the end especially if they contract everything out ( the lowest quote I got for the ADU was about 60-70k but that was just an estimate and could have been more).Average rent for ADUs in my area:1 bed 1 bath- $1000-$13002bed 1 bath- $1300-$1600Something tells me they can go for a little bit more because I had tenants bidding for my unit within the first week of construction.

With enough knowledge you can make a educated decision on which approach you take.My experience:I personally don't sign up for any program who take you aside during events and try to sell packages that is just blatant sales strategy.Once you sign up there is every attempt to make you sign for their programs for bookkeeping, registered agent, LLC or corp setup fee which have ridiculous even with platinum membership.Basic standard structure they suggest to take advantage of multiple deductions can be easily achieved by proper education or work with a good firm like https://wcginc.com  who is local to you.A umbrella C-crop to manage all other LLC properties and take advantage of many tax deductions that are not available with a llc, its also used to take losses up to 100K as startup expenses and dissolve the entity after few years.Few LLC entities for investing in Real Estate, etc preferably in Wyoming or Nevada ( you can find many companies online who can do this for $150 compared to anderson $1500-$3000) , they will claim they have a secret Operating agreement which is bogus.They certainly try to take advantage of tax loopholes and claim to be smart people, my view they are just taking advantage of numbers as per their own statements.
