I finished my masters in predictive analytics last June and I've toyed with the idea of merging my analytics chops with my newfound interest in RE. 

Plus the hassle of hauling it to and from, and the time spent sitting around at a laundromat makes it really tempting for a tenant to spend more on rent for a place that will let them have a washer/dryer.  

After about 8 months I got my first call about the tenant/property from a neighbor and found out that the tenant had been hauled off to jail and the house had been trashed over the past several months.

It requires some maintenance but it's 2X as durable over the long haul.

Resident agrees not to place into any drain lines of the Premises any non-approved substances, such as cooking grease, sanitary napkins, diapers, children’s toys or other similar object that may cause a stoppage.

At least 50/50, since you knew the oil was there and left it there, and possibly higher for you unless you could prove the tenant was explicitly told not to mess with the barrel because you were having it picked up and hauled away, and they did it anyway.

They also needed access to their vehicles parked onsite while they used the company trucks to haul material to the work sites very early in the morning.An electrical surge caused by lightening and thunder one night around 12:30am was the reason. 

I'm in for the long haul.

They left furniture, clothes, trash- everything – which we paid to have hauled away.

If you buy all these stuff that is recommended here you will need a trailer to store/haul it and a big credit card to pay for it - and you may never use 80% of what you have bought.
