If tenants are already paying the electric bill then I would switch to a heat pump or install baseboard or wall heaters. 

The MN standard lease only states normal wear and tear vs excessive damage.The large holes in the walls should be considered excessive but I was wondering if there was any kind of list that states what is normally considered excessive damages.thanks for your responses..

I will be applying for my exam and license soon, but I am torn as to which broker I want to hang my license with.I'm not so much concerned with commission splits or broker fees.  

The implied warranty of habitability requires landlords to maintain their rental units in a condition fit for the “occupation of human beings.”86 In addition, the rental unit must “substantially comply” with building and housing code standards that materially affect tenants’ health and safety.87A dwelling may be considered uninhabitable (unliveable) if it substantially lacks any of the following:88• Effective waterproofing and weather protection of roof and exterior walls, including unbroken windows and doors.• Plumbing facilities in good working order, including hot and cold running water, connected to a sewage disposal system.• Gas facilities in good working order.• Heating facilities in good working order. • An electric system, including lighting, wiring, and equipment, in good working order.• Clean and sanitary buildings, grounds, and appurtenances (for example, a garden or a detached garage), free from debris, filth, rubbish, garbage, rodents, and vermin.• Adequate trash receptacles in good repair.• Floors, stairways, and railings in good repair.In addition to these requirements, each rental unit must have all of the following:• A working toilet, wash basin, and bathtub or shower.

One thing about Airbnb they cater to the guests and leave the hosts hanging at times but I love their platform and I think it is the best one out there.

Its an older building, so there are not dual walls between the units;  I imagine I may have to remedy that, as all the condos I've seen need to have an airspace between them.  

Same with your local diner/hang out/coffee place.

Do you have plans on where you want to hang your license?

The problem with my analysis is that you will bleed tons of cash for about 2 years, but if you can hang on for two years, you'll be okay!

I might hang a curtain rod.
