Also, I failed to mention that 2 flowering trees are completely gone and I assume they died and was removed. 

@Shavas Flowers  For my first few rehabs, I did seller financing for the purchase, and brought in a combination of friends funds and credit cards for the rehab. 

Never late, grew flowers in the front yard, and it took me by surprise.  

In one four plex we own there is an older lady that is the mother hen and takes care of all the common area cleaning, sweeps the front area, puts out fresh flowers, etc.

The lady that bought it really loved 2 things-the kitchen I re did and put in with a snack bar and the terraced front yard with flowers, lots of bulbs,  burning bushes, fruitless pear tree, etc. 

Also, a great YouTube channel on this is Lili Thompson's.

Yup know the type well.. as we all know the hippies and flower children of the late 60S San Francisco  ended up moving north up into N.

I’ve seen a few options online from some of the YouTubers like Lili Thompson has a packet for like $300 and Jerry Norton service is $100 a month. 

If they ever go into the next month, that's a red flag worthy of initiating eviction proceedings, but if they're constantly 3 weeks behind and are paying you over $1k per year in late fees, I'd send them flowers and champagne.

@Lily Quan That is great advice.
