They have dropped the ball on me and my businesses many countless times in the last year or so.

It usually takes several weeks or more for the court hearing, so she still has plenty of time to pay what she owes (including court fees) and get back in your good graces.If you keep giving her additional time, you'll get behind the 8-ball.

Does anyone have any connections we could start with to get the ball rolling?

Like politics, real estate is local (even hyper local sometimes) and none of us have a crystal ball.

It's going to take time and LOTS of phone calls but keep at it, your consistency will make the ball start rolling.

However occasionally a client starts as a FSBO, and then switches after getting tired and frustrated of receiving low ball offers, or a low amount of offers.

I have no idea what the outside temperatures are (ie it is really hot out or cooler) and is she doing things to help keep the house cool? 

If it is mostly smoke damage to the interior it will be ok, but if the roof caught fire and burned away that's a whole different ball game.

With that said, you could at least obtain some "ball park" figures by reaching out to professionals who typically perform/complete routine and major home maintenance.  

You could charge a flat fee on utilities with a clause that states if bills exceed $X, then you split based on square footage.I've done all of the above and it has worked out.Regarding the thermostat, you may want to put in a mini split for the JADU in case your tenants like one way but you like the temperature another.
