There’s no bad blood.

'Blood from a stone' and all that.

It just makes my blood boil.

As far as LVF selection goes, from my research a thinner (3.2 - 4 mm) LVF plank that will hopefully be more flexible to handle the not perfectly level hardwood floor underneath. 

If you do go, it's because you have a sick relative somewhere who needs to see you before they go on to glory -- the best kind of story for that is an expensive one, like a blind half-brother with a rare blood disease who is only free of constant pain in this one remote high-altitude institute in the Cascades...something so outlandish no one would make it up that at the same time implicitly explains why you need the rent checks to be on time.

Now if the deal is much thinner then your risk to reward ratio can be way out of whack.

Who said buy when there’s blood in the streets?

No spirits can stay once you speak the word of God and the blood of Jesus.

What you have suggested in the OP sounds good, but rest assured if there is an incident, the victim will sue the "deep pockets" landlord before the "blood from a stone" tenant. 

Our market is pretty good right now but deals are getting thinner and thinner especially for multi families.
