One of our MTRs is in an area with extremely low supply that we've had a waiting list for it one summer.

No listing agents needed. 

The property had a first mortgage, as well as a second mortgage, both from the same purchase money lender.After receiving the trustee’s deed and recording it, I discovered two “Independent Solar Energy Producer Contracts” recorded against the home.

The listings @Joel Oh showed weren't in the first 50 listings for my search.

I’ve just made an offer on a building and the listing commission was 3% paid by the sellers.

marketing such as google adds, Facebook, direct mail and I'm sure the list goes on.

We keep making those lists for the biggest rent decreases, highest vacancy, etc.

@Kyle Carter a list of questions is almost useless:(Anyone can tell you want you want to hear, especially "con-men".

You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.

Like me, you’ll quickly discover it’s not a walk in the park.
