Maybe partnership with general and limited partners but I’ll have to talk to a lawyer about it.

@Greg Mayer - I heard a lawyer point out that “keeping the yard in good condition” is a relative statement and hard to enforce lease verbiage when issues arise.

Get a title company/lawyer/real estate agency involved to hold it as an 3rd party.I don't know if I'd be 100% sketched out at this point, but I'd start putting time limits on them.A lot of people are VERY bad book keepers and have terrible organization.

I would advise you to consult a lawyer for legal advice.

Sure, the Realtors could have/should have done more research to determine the current state of the title and to review the closing documents (some of that burden is on you, as well), however ultimately I think its the lawyer at the title company who had the responsibility to catch this.

For the disclosures and tax returns, can the lawyer that would be helping me with putting the property under contract help me out with this?

100% agree that getting to know people in the industry who are brokers, lawyers, lenders, even other newer syndicators who are around 1-100m aum to get a sense of how they are dealing with the process of getting their business started. 

Or even better, a good lawyer who specializes in parks that can write one up and guide me through what I need to be aware of?

You can probably stipulate the method of payment, but I'm not a lawyer :D If you're changing it after the fact, it may be a bit harsh to go to ACH.

(I have a great lawyer who listens to Bigger Pockets, if you need one.)
