I follow the 2% and 50% rule for my investment properties but my home is also multi-unit building and it's not close to the 2% rule. I would never find a place that my wife and I would be willing to live in for any length of time that could. However my mortgage is fully covered and I live in a nicer home than I would have otherwise. If you are planning on buying the place and then moving a year or two I think you should find something that matches the 2% rule. If however you are going to live there for 10+ years I would compare the costs to that of a similar sized SFH and decide which will be better for you.
You would need to add the cost of your unit if you were to rent it out to calculate the 2%. From what you posted above it looks like you would be at 1%. That would be a pass as a straight investment.
Including your $1500 the 50% rule would leave you with $2225 for your mortgage and profit. Since your mortgage is above that you will be sucking money each month. That is how you compare to a SFH. Calculate how much you are going to have to pay each month and compare it to that of a similar SFH. If you feel the savings are worth the hassle of the tenants move forward if not don't.
I personally have been very happy with my decision to purchase and live in a multi-unit property. I never am worried about making my mortgage and I probably would be house poor if I had bought something comparable that did not have the 3 apartments.
