If it's just wall moisture, no puddles, I'd put in two dehumidifiers and a couple fans.

In any home we own that is not tenant occupied, we put in an alarm, motion sensors and cameras so we can see what's going on inside the property at all times.

I put motion flood lights on all my properties.

Meaning, once you set them in motion, changes in the economy, changes in your personal financial situation, changes in laws relating to the management of your (former) assets, etc, may hurt the value of your trust, but you can't really do anything about it.

A landlord must provide due notice before coming into the premises in all cases save that of an emergency: eg. a weeks notice to affect repairs or inspection of the property; 24 hrs to show the property during the last rental period before the tenant vacates.If the tenant can establish proof the landlord is coming into the property unannounced and uninvited - perhaps a motion activated webcam - then they can make a case to the relevant authority - here it would be the Office of the Rentalsman.

Document your decisions/meetings (if multi-manager) and memorialize in a formal motion/resolution book.

You need to file a motion with the Court and request that the Court pay you money currently in the Court registry.

I’d be more inclined to do something else - like put up a motion activated security light that covers the driveway (or wherever the car is parked).

Get a dehumidifier in there as soon as there's a place to put it out of the water.  

the motion detector is definitely less sensitive than my home alarm.
