There are a couple of local meetups/events I know about but I'm still learning.

I know it's unlikely, but in that event, I think a client could sue a property manager for negligence.

The contract I could find says the following:```...together with the right of ingress and egress at all times for the purpose of mining, drilling and exploring said land for oil, gas and other minerals, and removing the same therefrom.And said above described land being now under an oil and gas lease originally executed in favor of [Oil Company], Chicago and now held by [Oil Company] it is understood and agreed that this sale is made subject to said lease, but covers and includes of all the oil royalty and gas rental or royalty due and to be paid under the terms of said lease.It is agreed and understood that of the money rentals which may be paid to extend the term within which a well may be begun under the term of said lease is to be paid to the said [purchaser], and in the event that the said above described lease for any reason becomes cancelled or forfeited, then and in that event, the lease interest and all future rental on said land, for oil, gas and mineral privileges shall be owned jointly by [owner] and wife and [purchaser] each owning & interest in all oil, gas and other mineral in and upon said land, together with interest in all future rente.This sale is made for and in consideration of the sum of Ten Dollars, cash in hand paid, the receipt of which is hereby acknowledged.To have and to hold the above described property, together with all and singular the rights and appurtenances thereto in anywise belonging unto the said [owner] heirs and assigns forever, and we do hereby bind ourselves, heirs, executors and administrator to warrant and forever defend all and singular the said property unto the said [purchaser] heir and assignee against every person whomsoever lawfully claiming or to claim the same or any part thereof

They also held two annual events in the Fall and Spring that drew in over 100,000 tourists each.

You need to target recent or currently in bankruptcy, has liens on the prop,  just had a medical event, or is late on some payment 30-60=90 days late. 

For more visibility, consider cannabis trade shows and industry events.

And the whole event had a very casual feel.

I tried to look up your post you mentioned but you have so many threads here I wasn't sure which you were directing me to.anyway, I am in contact with a surveyor.. but waiting to sign the purchase agreement before I get the ball rolling. this property is in city limits and have been on contact with the planner. the 5 lots are within their parameters, this will have to be on city water and sewer.
