You'll also want to ensure you have a good property manager to look after the upkeep of the property if you are not there to notice anything deteriorating or which may need attention.Creating an LLC in California could cost you a minimum tax of $800 every year.

I read somewhere it was a requirement and I went to call and electrician to fix in one of the rooms. but the inspector did not even take notice of the room that did not have a permanent light fixture- so i guess it is not a requirement.

I need to issue an eviction notice.

Our local statute specifically says: "the tenant shall not be considered to be absent from the dwelling unit without notice to the landlord during any period for which the landlord has received payment of rent."

Buyer might not notice, but Buyer's home inspector will definitely notice.I bought one of these with a property in 2013.

No one will notice.  

Should I send a notice to quit a month before they move out?

I don't know where you live, but in California, I would immediately serve them with a 3-day notice to pay or quit. 

The lease clearly outlines the tenant responsibility and I'm notified of past due accounts which can lead to a 10 day notice to comply or vacate.

Another thing that makes the forum very hard to use  Yes I have noticed the number of clickbait ads on BP lately and was like whoa.
