For a 30 day notice, I'll use certified mail so I have confirmation of receipt For leases, disclosures, etc., I've sent them via DocuSign.

The agreement can be customized as well for example an agent can write in a clause that if you’re unhappy/ want to work with someone else then the agreement can be terminated with something like 72 hours notice (first agent would probably have “procuring cause” on any properties they’ve showed you already), or the client can work with one agent for one type of property/ a specific part of town and a different agent for a different investment goal.

Your analysis overall looks good but just wanted to point out a couple of things I noticed.  1. 

You may not notice rotting floor joists, but your contractor will.  

I now have to give this tenant a 30 day notice of non-renewal.The unfortunate part is this tenant had to move out all their belongings by January 31st in Nebraska, which if you didn't know we get lots of snow at this time.

Hi all,I’ve recently noticed a whole host of properties on our street that are currently without tenants and have been neglected.

I noticed in some listings the agents put the info but in lots of others it is not included.

@Dave Carter Side question: I gave the tenants a 5 day notice last month.

Don't blow it.If you do decide not to renew, give her P-L-E-N-T-Y of notice (far beyond what is legally required) of non-renewal, so she can smoothly move out.

Immediately served a notice to quit and placed new tenants Ive vetted on my own 2.
