Have also used list source and prop stream before but the data they provide is very similar to what I pull off the tax records through CRS Tax. 

I am not really sure what to do in this scenario. has anyone had any similar experience? 

I encounter this semi often as I broker to buyers and also own a PM company so often have to do the same or similar transition as you are looking for, for my clients. 

Very similar to my units.

I have several current and former clients that have done similar projects, mostly in neighborhoods where either 1) they grew up in the neighborhood, 2) they still go to church in the area, or 3) they have a relative that still lives in the area.

@Zach Denny  Similar to what Minna posted above, I have done with a local portfolio lender bank where they set their own lending rules. 

Similar to the comments above on using FurnishedFinder, also check Airbnb and sort for 30+ day rental options. in addition, I'd recommend talking to the local university and hospitals nearby by calling to their various departments.

The homeowner collects a NET/NET 5% yield with 1% increases each year in long-term lease by a BBB+ credit rated tenant (similar to Morgan Stanley credit).

I am seeking advice of what to do with the money from someone who exit the business and successfully got similar income and appreciation of capital.

The procedure is very similar to 1099-NEC: file it online.
