You said in your post  "If the notice was delivered by mail then the notice period begins when the Tenant actually receives the notice."

If the latter, simply give her the notice required (eg 30 or 60 days) that she needs to move. 

They had no common sense what so ever.  

I notice that "Notice of an Independent Solar Energy Producer Contract" comes up a lot when filtering through Liens.

Law websites like nolo and others have said if the tenant in NJ has made partial payments then you have to give them 30-day notice before you begin the eviction process.

The fear of renting while out of town is common, but it's easy to overcome, especially when you have friends and a handyman.

I ask them if they've already given notice.

Should I try to make the deck on the second floor a common space or as part of a large bedroom?

While it might feel like an extra charge to tenants, these packages often provide value that indirectly benefits the property owner as well—like reduced maintenance calls or ensuring the property is better protected.In my experience managing a large portfolio of properties, these fees are becoming more common due to the thin margins in property management.

If someone was over during a high consumption month I'd give then a notice/warning for the first month along with some energy consumption tips then tack it onto the rent.
