Property not easily financed due to condition.

Talk to a lawyer I believe there are strict regulations for this, especially if you are soliciting money from strangers.

Note that I only look at properties that are virtually turnkey—clean carpet or vinyl “wood” floors, reasonable interior condition etc. 

Never lend more money than the property is worth in its current condition - in case you have to foreclose.

They'll be able to give you a better idea of the condition of the park.

It sounds simple, but depending on how many documents/checks you'd be signing, it might be easy to slip up.My instinct is to say that if you need to ask the question, chances are that it's better to keep your life simple and just personally be the member of the RI LLC and have it be separate from your MA LLC.But I'm not a lawyer or an accountant and you should probably ask this question to one of each to get advice for your specific situation.

What do they say or do to give them unit access and see its condition? 

Part of her decision is the overall condition of her neighborhood. 

That said, I'd like to raise the rent by $25-$50 per month and put them on a 12 month lease with the condition that if they found their home, they can move out once we find a replacement tenant (and we would focus on securing a new tenant ASAP).  

@Greg Tunes   You have not provided enough facts to get any good advice except... ask an lawyer in Louisiana.
