I agree with @Ray Harrell - you need to understand what is common in your area.In Chicago, I would never recommend a landlord put in unit washer and dryer unless they are already doing a full rehab of the unit. 

It's common to have an illegal basement unit in Chicago but it's obviously a risk.

It may be a tenants in common relationship.

Inquire about any past maintenance done.

I have never done it but it is fairly common for some to get started house hacking a smaller multi family property. 

She put us in touch and he agreed to take my property on, and we both signed a property management agreement in January 2016.I won't go into the details, but he stopped sending me rent claiming high maintenance expenses to which he coming up with excuses for why he couldn't send me the receipts for. 

Most are in Mpls or St Paul, but you will find some first-tier suburbs with large duplexes.  3-4 plexes are as common as a Vikings Super Bowl outside of the two cities.Within 45 minutes of MSP airport: This will be no problem, everything is within 45 minutes of the airport, especially in multifamily.Areas with a small town/ neighborhood feel are a big plus: South St Paul would have this feel so would Stillwater but that is probably more than 45 minutes from the airport with any level of traffic or bad weather.

Otherwise I would expect the story above is the most common. 

I'm a little leary to think that 6 nights (3 weeks * 2 nights) is going to be enough to cover mortgage, insurance, property tax, maintenance, cleaning, furnishing, 100% of utilities, cable, internet, etc. but maybe I'm all wrong. 

$1650 rent less $1375 PITI less 5% vacancy ($80) less 10% management ($165) less 10% maintenance ($165) less 5% CapEx ($80) = Negative $215 per month cash flow.
