I agree with all of you, with most of the dogs I see everywhere, I would not hesitate to throw them into a kennel or chain them up and walk away.  

I am also active with the government affairs committee of MABA (Madison Area Builders Association).Personally I am pretty interested in learning more about other Wisconsin markets like the greater Milwaukee area, the Fox Valley, Eau Claire, Etc. 

When advance notice of 24 hours or greater is given, all dogs in the unit must be crated/kenneled.

I've also read on Ross Chapins website regarding pocket neighborhoods, and ran across a concept drawing that had a common area building with kitchen, and individual bedroom suites (he is under the impression that Planning Departments classify a property a residence if it has a kitchen, therefore; it's not the number of bedrooms/baths, it's number of kitchens that push a property up to MFR - though I haven't received an answer from Planning on that yet) The point is, there are many variables that might be considered in different areas that allow a shared type housing.

There are kennels that will board dogs ... but for a fee.

I don't do pets,, but have had worked for properties that do and it's always a mess, more laws that protect the animals. now landlords have to pay to kennel the pets for 30 days just like storing furniture.. so figure the cost of the eviction, and what it costs to kennel a pet at a boarding faculty, and then see how much of  a deposit makes sense if you let people have pets.. not to mention the clean up 

Most group properties by area, building or something else.Most commercial banks you will want to do business with are locked into a state or a small number of states, so investing out of state gets harder as your splitting up your business relationship with other banks in each service area.

They used the deck as a kennel and that's terrible.. 

The multifams that I'm looking at vary from $100k per unit up to $200k per unit depending on area, building, and other factors 

I would suggest talking to a local bank in that area.
