Look at Homes.com or Realtor.com to get an idea what that type of property is selling for (look at the ones Pending or Under Contract)...or, look in the county's GIS system to see what similar properties sold for.Once you have an idea what a fair market value would be, let the landlord (if they're interested in selling) mention their price. 

House hacks are fairly straightforward regardless if the units are separately metered.

What would a fair cut of the profits be?

As far as self managing, it’s fairly easy.

You want to play the charitable hero.

Umbrella insurance will never come into play for Property damage (fires, storms, floods, etc.)It is liability coverage only.I'm an insurance agent and have seen umbrella claims from fatal car and boat accidents.
