If they conveyed what the offers were in writing, I would have at least an opportunity to outbid on this cash sale and the property owner would have an opportunity to receive more than the value of the property.

Here is just one discussion thread that might be helpful:https://www.biggerpockets.com/...Not sure how your state works, but here I would write the purchase contract with the buyer as "dan Walker, 'et al'" or an entity to be formed." 

"(8) If the tenancy is for occupancy in a dwelling unit that is located in the same building or on the same property as the landlords primary residence, and the building or the property contains not more than two dwelling units, the landlord may terminate the tenancy at any time after the first year of occupancy:""(B) Without cause by giving the tenant notice in writing not less than 60 days prior to the date designated in the notice for the termination of the tenancy"The lenders will not accept it because it cannot be done without you living in there in the first place.

If you had nothing in writing before he started and the only hard copy of the bill is what you have after he is done then you are on the hook for it.

From there, write your why down somewhere where you will see it everyday and remind yourself why you want to achieve success.

Folks still write paper checks or send you payments via bill pay?

the ONLY feedback is going to generally be negative and frustrate the seller.On my high end flips in Charleston  IE 1.5 mil to 2.0 mil there is a on line feedback from the showing agents that comes to us automatically our listing agent sets that up.. and as stated its more frustrating than helpful.IE 1. did you like the home                          No or yes if they dont write an offer its NO2. is it priced right                                  If they dont write an offer of course its priced too HIGH3. things you liked                                  House is nice but not a fit for our family4. things you did not like                        did not like the color of the Primary bedrooms bathroom and on and on.So bottom line if your not selling your over priced .. if its an odd floor plan or anything like that you should as the owner and with your brokers help understand that  and that its an impediment.. 

I could spend a few days writing to you about this, reflecting on my own regrets of the past twenty-five years and how I wish I could go back and do what Scott Trench suggested, but you need the book more than you need me talking about the book. 

Basically, have a system in place and in writing.

Notifying in writing the relevant participants in a sale intending to squeeze you out (seller, would-be buyer, any title company considering handling that transfer) as what you intend to file/record and do is the best way to prevent that sale.No title company who receives notice of competing contracts will close with either buyer until the situation is "resolved" ... by resolved I mean the attorney involved will consider all the docs and facts and may decide that closing with either is not worth the risk.It depends upon where you and property are but just as an fyi title companies around here (East coast) don't represent clients or file things for them.
