City liens are considered government liens and they are not extinguished.  

The local government had my contractor create some basic drawings of the work, had me pay the permit fee and pay for an inspection. 

Quote from @Jason Malabute:  I really hope they figure out a way to extend this in the future because it’s a huge benefit for real estate investors like us.This is not how the government works though :) 

They are essentially risk free, as they are government bonds.

STRs also make for a convenient scapegoat for the government when they need to divert attention away from their own policies that make adding more housing units more expensive/time consuming. 

MFH carries all of the emotional issues and local governance that tends to favor tenants over landlords because you're dealing with "people's homes", not an investment property.

Most halfway houses and similar stay solvent through donations, government grants and insurance billing.

A unit of government?

Undocumented immigrants often won't have any government issued IDs so it is a defacto fail.

I needed to provide vendors an “RNC” number that they used to provide the government with the expense.
