When scheduling the exterminator to revisit the house (which I planned to pay for again), she mentioned that the technician noted in the report from the first visit that the tenant had a pet rabbit roaming around the house, and that rabbit food and feces attract mice.My lease states no pets allowed, and I also wrote that on the listing.

At this point Massachusetts really only allows evictions for “safety reasons”.

Still, the new unit will be subject to the commercial code ($) with additional construction and safety requirements.

Are there any systems you would recommend or that others have had food experiences with?

Any service person who comes to the house should be wearing a mask and taking the proper safety precautions. 

and immediately bought flat screens, drugs, beer, excessive toilet paper...I wonder how many of those checks got cashed at a Walmart and then spent there without a single food item? 

If people can't afford to buy food, they don't pass a law requiring grocery stores to give it away free.

A decent low cost breakfast, luggage storage, safety boxes, daily activities such as bar outings, outgoing staff to engage with the guests, and a good cleaning department will have you as top hostel on Hostelworld in no time.

Saskatchewan supplies the world with a tremendous amount of food, and I can only see the demand for this land growing as populations grow across the planet over time, which equals more mouths to feed.

I also have access to a relatively substantial amount of HELOC money, we keep it as a safety net, but would it be wiser to draw that down and use that for the down payment?
