Once confirmed, they will be passive and can meet your expectations as described.The STRs, fall in last place according you what you've expressed.

@Christopher HeidrichRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

They they get a big fat default judgement against you. 

ARV Potential: Where can we expect to achieve higher ARVs?

If it’s all natural and not preventable and people expect to be able to buy insurance.

@Chris Hains  all in price , vs what you are expecting to sell it for , KEEP IT SIMPLE.

Lots of people who have trailers don't own the property they are on and sell them.As for the owner of the land expecting tenants to do repairs-there shouldn't be many repairs required to the land, just the trailer that is on it (which your grandmother owns and should be responsible for maintaining). 

In fact, it's a common and expected practice.What rule do you feel was violated?

Those failures are  more negligent than a PM allowing a guest who paid with expectation to stay at the house to remain there in the middle of winter when they arrived on a Friday evening as you described.For now you will have to rely upon insurance, I don't believe the PM acted unreasonably given the circumstances.

The more properties you acquire and refinance, the greater your returns can be.Potential Risks and ChallengesWhile the BRRRR strategy has great potential, it’s not without its risks:Unexpected Renovation Costs: While you may expect to rehab a property for a certain amount, surprises can arise, especially with older homes.
