In Seattle I could not reject tenants convicted of drug dealing into my multi family complexes that have kids. 

I own a 4 plex row complex 1890 two commercial on bottom and two residential on top.

@Allyn Witt there are a lot of things to take into consideration from type of construction, mechanical systems, lead paint, asbestos etc.I have done a lot of conversions of old historical buildings such as  school buildings, hospitals, factories, office buildings etc. and converted into apartments, condos, mixed use and office.I would be happy to discuss more in depth as these types of projects are very complex and there is way to much to go into than can be posted here. 

A unit just listed for rent in the same condo complex as mine for way, way lower than what I would need to even maintain a -$60 cashflow. 

and subpoenaed the footage from camera in the common area of a complex.

I found a seller who wants to sell 8 townhomes (4bed/2.5bath/2200sqft each). They currently rent for 2200 each. 5 of them have 12 month contracts on them, the other 3 are currently vacant due to renovations being done...

I am looking to cash-out refinance a 5-unit apartment complex that I bought back in 2016.

For the price, an apt complex would be a better investment I am thinking. 

They can be as basic and straightforward or complex as you like.

Thank you Immanuel, I am looking at a 6 unit complex.
