You probably won't get year leases (which you don't want anyway), but make sure they understand that it is a month to month arrangement that can be extended for as long as they follow the rules.

The landlord shall arrange for the removal of garbage and rubbish from the premises unless the parties by written agreement provide otherwise.

I would love to arrange a time for me and my brother to speak with you!

Get a commitment from her to have the grass cut by a date or to make arrangements with a lawn service by tomorrow. 

Our financial arrangement is my partner will put the 10% down for the HM lender, and pay closing and holding costs ($65k anticipated) My construction company will be doing the renovation, and I intend my company to bill our partnership for costs incurred (direct cost, no markup obviously).

As most of us know, Section 8 requires an inspection before approving the property, setting the rent amount and approving the lease arrangement. 

I've obviously seen all kinds of wholesaling contracts around the internet (Purchase & Sale, Assignment, etc.) as well as several JV agreements, but I have no idea what kind of agreement it would take to put that kind of arrangement (someone inspects the property for X% of the profit of the potential deal) into writing.

Anything else I should use, or know where I can find standard lease verbage that covers this arrangement? 

Even an hour adds complexity and difficulty arranging things and costs a lot in fuel and time if you self manage .

If Ihave a properly arranged SDIRA, and put the property into an LLC owned by my IRA, can I take payments in exchange for the landlording work?
