Use the money you pull out to buy the new homes.If you let your mind look for answers outside the box, you'll often realize there are ways to make things happen that aren't "either/or".  

What are the showing instructions, lock box etc?

Did you check the NOO box?

Simply click the box in the upper right corner of the post!

For each line-item, you can get an idea of the material cost by visiting your local big box store, building supply shop, online retailer or talking to other investors. 

I would budget $6k for a small house.What they will need to do is break up about 18" of the floor around the entire perimeter, install perforated pvc piping pitched to a corner that has a sump pit and box.  

I've looked around at the big box stores for replacement sections of this trim but cant find anything like it.

This will take you to a list of the counties in that state, click on the desired county or type the city and state or zip code into the box below and it will tell you which county to click on.Once at the right county, you will find the links to the local property assessor's site, register of deeds/clerk of courts, tax collector's site, along with mapping and gis sites etc along with phone numbers to their offices if they don't have a site.  

So it is no cracker box, which is fully 1/3 of the reason I would want to keep it.

That being said, you COULD communicate to your tenants that garbage cost is out of control, and clarify what is "regular household" garbage, remind them to break down boxes, etc.
