If they are fine with the estimated net amount of proceeds (much like having a conversation about closing cost credits), you don't have anything to worry about.However if they want a buyer at $X because they want a fast sale, and you agree to buy it for that amount under contract and agree to close fast, you should be able to perform - be it yourself or via someone you assign to.

Its not 30 days from the notice date but rather 30 days from when their current tenancy period ends.In a human way, just approach the tenants with your notice in your back pocket and explain that you purchased the property with the intent to rehab it, and need the property vacant to do so as the work being performed will be intense and intrusive.
