Just take your lease paperwork and make the term 30 days.

I have a few gray areas when it comes to the seller financing paper work.

Sellers may show a much lower # on their paperwork. 

Is it legal/ what paperwork do I need to create a second unit?

@Greg Gaudet I'm still at that paper work phase Learning to analyze a property.  

In MN. my brother got a realtor to do the paperwork for $500.

So I had an attorney write up the LLC paperwork and file it.

So, for instance, your agreement with the seller is for $250,000 and your 25% carry back is $62,500 and your lender will lend you 75% or $187,500 based on the preliminary paperwork.

@Austin YoumansAs a general rule, an LLC doing business in only one state is better to be established in that state and an LLC doing business in several states should be in the state of your residence unless you have a specific reason to be in a different state.Typically any LLC established in one state but doing business in another, will have to file all the paperwork for both states with the associated costs but no additional protections.But definitely check with your legal partner. 

If there are delays in providing paperwork or more verification is needed, it could take 30 days or more.
