If they were long term I would let them break the lease and if the home was left in good condition then I would return the deposit - now this is just me but you have  alease that dictates specific terms that you can uphold them too or not.It would be ok to ask for the death certificate, and what you could say is its our policy to waive the fee for death but we need a record of it.

Place is in general good condition other than the persistent stench of pot. 

@Jin ChungWhat condition is the property in?

Hey Nicholas, I know we texted the other day but happy to give some feedback here as well.Look at the general condition of the house itself like you would any other property.But in terms of tenant quality, take a look at how they're living.

Each Scope of Work (SOW) is unique to each property, as the specific needs of each flip vary widely based on the property’s condition, location, and target buyer.

Quote from @David Felt: You are responsible for maintaining the home in its original condition.

On the flip side, there is some conditional love at play here that you need to think through. 

Insurance companies will likely not pay a claim from the roof or subsequent water damage because they will know the roof is already in poor condition.

Opportunity to purchase from prior owner as is in run down condition How did you find this deal and how did you negotiate it?

Also, before non-renewing I would walk the units if you haven't already and get a feel for the condition of them.
