One way is to force appreciation, through improvements.And she has your perfect path (in my opinion): to buy a property that needs slight improvements and updates.

We improved the amenities by extending the pool deck, adding a large pergola, bought new pool furniture, and added a grilling/seating area.

Just offering the chance to give someone's a break for knowing something when I can learn it for you and then give you the info you want. 

I hope to start investing in South Jersey so I can focus on my first property and learn from the things I do well and also the things I can improve upon.I am so excited to join the BP community and more than willing to put in the hard work to learn from all of you!

It is a process which will probably involve giving them notice and a chance to correct, before you can ultimately do an eviction.Either way it sounds like they are/will be difficult so I would strongly recommend consulting an attorney who specializes in evictions.

Not too many commercial lenders are going to refi you based on ARV of the property 3-6-12 months after purchase just because you made some improvements to add value.

Is there an HOA or CAMs for this building by chance? 

(b) In the event sellers refuse to pay, do we have a chance to prevail judgement  and (c) Is it worth fighting this case given the PSA is for a low 7 digit price?

There's furthermore a magnificent chance that any gesture you make with a book about home maintenance will be interpreted as an undercover effort to tell your tenant that they're on their own if something goes wrong and not to call you.

If you don't get the chance to either attend live (next one later this year) or want to get the recordings (last one was October 2018 in Henderson, NV) I highly recommend you reach out to Jillian regardless, for if & when you decide to move forward in setting up a PPM.
