Us investors after all deliver win win solutions where everyone has to win. 

I bought some Ron Legrand home courses, Wholesaling, Seller Financing, and Lease Options, back when you could get the workbooks, forms, scripts and tapes delivered to you in the mail.

So, had to drive an hour to the house to deliver an eviction notice.

I have seen it many times where a borrower goes to another lender or broker for a better rate/lower fees and they could not deliver on their promise...

The lease is a standard lease and doesn’t mention anything about how notices have to be delivered. 

It's a mix of him delivering content and interviewing others.

If it does and the tenant doesn't pay his share of utilities, you can deliver the 3 day notice to pay or vacate to enforce the tenant's not paying additional rent.

That requires you to be able to send them a certified letter or have a process server hand-deliver the notice. 

If the tenancy is at-will, you can deliver written notice of the rent increase by giving the number of days' notice required by F.S. 83.57. 

The proceedings went on for two years because the mortgage company couldn't show that the house was vacant but also couldn't prove that the notice was delivered/received by the prior owner.
