Same reason why you probably do not want to try Beef Wellington as your first cooking project or the Grand Canyon as your first hiking route.

You would want to ask what quality checks are performed (framing, drywall, punch, etc) also ask for any third party inspections (building envelop, geotech, water erosion plan, etc).Usually for 4 units vs single you are going to have fire assembly differences - 1 HR- 2 HR rated and/or sprinklers requirements and sound transmission requirements - beefed up walls and floors.If you have additional questions DM and I'm happy to help.

Don't know what type of beef they had with the previous owner... but they vandalized the house. 

We should have beefed up the loan a bit higher.

I recommend beefing it up as others have recommended.

Each unit gets their own meter, the service cable to the utility is beefed up for modern device extra power draw, each unit has their own circuit breakers.

Just a brief little "beef" with these auction websites.

A byproduct of this is focussing energy and resources on a potentially benign situation, while being distracted from focusing on specific instances, which may have caused direct harm.

You're only options are to beef up the insulation between the roof and the conditioned space to prevent heat transfer or add an additional AC unit to help keep that area cooler.
