On your next day off want you to pack your bags for an overnight trip.  

Not having one is like walking into a networking event with a paper bag over your head!

A good way to classify A - B - C - D properties are by the shirts your tenants are wearing.A Properties = White collar professionals wanting nicer amenities to entertain friends.B Properties = Blue collar working class, bread and butter cash flow tenants that respect the property.C Properties = T-Shirts week-to-week paycheck residents, usually a mix of Section 8 and working classD Properties = NO SHIRTS gathered on the front steps drinking 40's out of a paper bag at high noon.

We supply anything that is shared (toilet paper for shared bathrooms, trash bags, dish soap, etc) so that tenants don't have to worry about whose turn it is to purchase supplies.

I also retrofitted the bottom drainage as the original was just cheap plastic & began to leak.

Left behind 48 bags of garbage. 

Don't be the investor left holding the bag of flaming dog s*&t.

Vacant is a mixed bag as well because vacant is split up into absentee (great target) and runaways (forget it).

There are some cheap components on some like plastic sinks and faucets, Uber cheap cabinets and odd shaped doors.

Tip:  We bought six rolls of toilet paper for each of our tenants and delivered it to their homes in a gift bag with the hand written message "We are all in this together, if there is anything we can do to help let us know".
