Two days ago, I got a call from them saying there is mold on their furniture in the bedroom, the window in the bedroom and living room and a bag they had on the floor by their bed near the exterior wall.

I have a couple in one of my units with very little furniture. 

Students often want simplicity and by offering the units as fully furnished, you minimize the hassles associated with moving while differentiating your property at the same time.You should be able to furnish a studio for $1500 and this furniture should last for a minimum of 3 years.

She left clothes and pans in her unit but all furniture is gone, fridge is empty.

Transport furniture?

I am debating about purchasing the washer/dryer (~estimating about 1200-1300 from looking at Home Depot) or potentially renting them from a furniture rental company and building it into the rent.  

I take pics showing all the signs of habitation have been removed (i.e. no furniture, beds, etc) and call it a day.Is there a chance the tenant can ding me?

If you have extra furniture, appliances or yard equipment sell them or donate them.Minimize your exposure to litigation and lawsuits.

From experience I know that military moves are fast paced and stressful so I did a few things to ease their transition;Made sure they left Illinois with keys already in hand even though their lease wasn't officially started so they wouldn't have to go to a hotel or wait to link up with my agent for keys if they arrived at odd hours.Left Directv hooked up and operational so they could keep the kids entertained during unloading.Sent a large fresh fruit and snacks basket from Wine Country Gifts so they could have something immediately coming off of road trip food.Left them some furniture so they wouldn't have to get everything unloaded right away just to have a place to sit and relax after a long trip.Left them recommendations for the best vet in the area in case they had problems with their pets upon arrival.Just little things that I hope made for a little less stressful day 1.

At least the usable furniture and appliances!!
