So, safest thing to do is probably send them written notice at their 60 to 30-day mark (sooner the better) that advises them, pursuant to the mutually agreed and signed contracts, since they failed to exercise their option to purchase they may now choose to transition into a month-to-month lease or move-out at the natural expiration of their lease term on whatever date. 

@Mark Guagliardo thank you for your insight.

In box 4 look for "Probate Letter sent to PR", then open and download.No, I don't use this letter as I have my own that I send to PR's.In CA, a real estate agent while farming for listings would have to include their business information.Good luck,Mark (N-CA)Sac/Placer counties....

@Pat Marco   hit nail on head... being a real estate agent for 500.00 commission is ridiculous.. either move or get out of the business or put money together buy the inventory yourself then resell it and mark it up. .thats why when I started way back when I only sold land... 10 to 15% commish and double ended everything..

I've had it marked on my calendar since the 'subject to' was done. 

Send a letter to PO box and in red ink  outside envelope mark " ATTN Post Master;  Forwarding Address Requested".

If it’s worth “X” and they don’t hit their mark within 10% they will pay you $1,000.

@Tom S. you should talk to @Mark Ferguson and his team.
