@Kelly Pierce i think you can come up with some unique incentives to get them to move, outside of just finding a new rental, which i suggest you do anyways.Just come clean to them that you are going to sell the property.

While other people can see the prices.....we uniquely see how many offers come in, and the terms of those offers.

Every situation is unique because of markets and personal taxes, etc. 

The depreciation deduction is unique, because you can take it for tax reduction, but it does not reduce your income for the lenders.

The address matched, and the tenant has a unique name.

Ask them if they're any unique ordinances surrounding MFH (there are in my market).

@Clarence Green what's your unique selling proposition to differentiate your wholesaling business?

However, the one aspect that did strike me as unique with them is that they approach data collection from an algorithmic direction versus a call and survey approach like Costar.

Also, each building has its own checking account and each unit within the building has its own unique rent amount (even by a few dollars), so I can tell that way, as well.(2)  My lease covers bounced checks, but I'm not sure how - other than collecting cash on the doorsteps - you can avoid that risk. 

@Ricardo DiazEveryone's tax profile is unique.
