The seller refused and now he is saying we have to make an agreement before the appraisal on what we will do if it doesn’t appraise for 315.

The bank seems confused by my request and the owner and I are in agreement on the terms and it's a good deal that really works for me right now.  

The expense is more up-front but is far more cost-effective in the long run.Regarding your specific question, unless they have an agreement with you there is no expressed or implied contractual obligation for you to hold the rent. 

I wouldn’t sign the agreement.

If you're really lucky they are part of the listing package...so hopefully you get what you want before you make an offer.Sometimes you may have to sign a non-disclosure agreement to get them.Sometimes you may have to ask for what you want.Unfortunately in many instances they don't exist, the listing agent doesn't collect them, the owner hasn't kept or produced them, or just doesn't want to share them. 

In the end, whatever you do, make sure your operating agreement is written up by a lawyer.

The co-owners may enter into a co-ownership agreement that runs with the land.5.

Which means upon default of the sale you do not have to foreclosure, may may take non-judicial repossession.Can anyone confirm if this means you could sell on owner financing and evict upon default with a land trust and proper agreement?

Unless your grandmother had an agreement that she would inherit the home, or his share of the home, then it would go through probate or follow his will (depending on the state and the values of his estate) or trust (if the house was titled to a trust). 

Or should I do an actual loan from myself personally to the LLC with a signed agreement / schedule, and pay it back to myself with interest?
