Buying with an LLC is a great way to safeguard yourself and your property, highly recommended, however, if you’re purchasing through an LLC that was not formed specifically for the purposes of acquiring your investment property, ensure you own more than 50% as LLCs can get complicated with multiple equal shareholders.

If so, self-managing properties might not be the best use of your time - In any case, I'd encourage you to talk to multiple local property management companies, keep the above in mind, and understand how they approach management.In my experience, property management isn’t just about finding the right tenant or collecting rent—especially in a tenant-friendly state like Rhode Island.

That is why we have multiple presidential candidates and the Fed has multiple board members. 

Generally there are multiple units for each "zone" if you will when I've seen them installed.Regarding your problem at hand, I personally would simply adjust your plan to move and make your initial plan to get the current issues resolved, while costly now, in the long run holding onto the unit will likely pay off. 

I spend so much time finding the 'right' properties across multiple markets on Zillow before I even evaluate in my buy box.

9) adding multiple ADUs or adding an ADU to a quad looses F/F conventional financing.

The tenant hasn’t been the greatest: late payment with not always paying late fees, multiple complaints from the neighbors, changing phone numbers, ect .

I have spoken to multiple folks in my same state. 

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.

@Paul Lucenti Not too bad dealing with multiple tenants in the same dwelling.
