Reminds me of when I bought my three family in bed Stuy in 2006.  

Do I say something now, reminding them they are required to keep the apartment clean?

This is a good reminder to always check backgrounds very thoroughly, look for red flags, and make sure to try and get the best tenants you can.

Robert Kiyosaki said that he hung a picture of a Porsche on his wall and that was a visual reminder of his original goal.

Then remind her when you're half way there, then 3/4 the way there.

Since she is month to month you can serve her notice to leave if you want or reminder her she is able to leave at her will. 

Stay tuned.Which reminds me, everyone should rent the movie "Pacific Heights".

My only thought was to remind me of a narrative that I used to decide NOT to follow up with a particular prospect, or something like that (ie. noticed he was 12 minutes late to showing, never called to give heads up, sounded like I woke her up when I called at 9, dog barking, eating potato chips while on phone with me, etc.)

I would NOT try to time the market to sell it at peak unless you had another compelling reason like mentioned above for wanting/needing to sell anyway ... remember, even if you hit the peak for this RE cycle (which is hard enough to do), it does not mean you will be selling out at the global all time peak ... it reminds me of something my parent's did in the 1980's, they timed the market perfectly and sold at the peak for that RE cycle ... it was a triplex a few blocks from the ocean they sold for $150k, value stayed flat for years after they sold but today is probably worth >$2M.

Reminds me of Austin a bit with all the live music, breweries, art shows, restaurants, downtown area (of course beach area too), amazing new Pier, etc.
