The process is similar to a regular eviction but with longer time lines. 

You will do him and yourself a favor as soon as you removed this burden from both of yourselves.

I just contacted a Denver abatement company last week.They gave me a ballpark (without inspection) estimate to remove all drywall of $10- $15,000 per 1000 sqft unit.They said for this age house it was likely in the wall texture, mud and possibly even the drywall itself

Also, I agreed to prorate the rent while removed from the property, am I a responsible for anything else (i.e., temporary housing)?  

The best you can hope for is a tenant that will voluntarily agree to terminate and remove their possessions.  

No idea what it cost but I'm sure it was cheaper than removing the old concrete, putting in new concrete, down time, new flooring etc.Digging the trench yourself at 61? 

Also, you could always login through your phone's regular browser.

We are currently trying to nail down a regular meeting time for 2016 but its looking like the 3rd Saturday of the month at 10am. 

One of the biggest is the ability to put ALL of the expenses on the tenant...all utilities, lawn care, snow removal.

Estimating snow removal at around $1500/year.
