Since this issue cannot be cured, there's no point of a Cure Period.

It basically gives them time to cure the violation or eviction will begin. 

@Ishmael JohnsonThe lease has to be in violation at the time you cite it in a Notice To Quit; a Notice To Quit is a Notice to Cease - it basically tells them that they are in violation of a lease covenant(s), to stop and cure it - or face eviction. 

I sent them a cure or quit and followed up with an inspection notice.

But she was a terrible tenant otherwise and was already under a Cure or Quit notice for constant, excessive noise.  

In my opinion, the cure for the debate on should you wholesale or not is to not simply wholesale.

(In my state, I'd have to issue a "Cure or Quit" notice giving the tenants an opportunity to fix the problem or face eviction. 

Once the renovations are done within (6) months refinance to take the cash out.Conventional allows for cosmetic issues or cost to cure repairs so find a distressed property or bank owned sale and go that route to protect your money.

Cost to cure needed?

There will likely be required notices/documents you must file during the pendency of the case (i.e. proof of claim, notices of payment change, notices of fees/expenses, response to Trustee's notice of final cure).
