Your numbers look ok except you cannot deduct the 1st year principle paid. 

Either way - I would support the petition for landlord relief on principle alone.

I’m telling my partner we should put that towards principle.

When you run the numbers out (principle, interest, taxes, insurance, appreciation, depreciation  write-offs, etc), having more properties with less invested in each is the most profitable. 

I will try to be as objective as possible.

There are some caveats i.e. principle reduction isn't liquid and only a benefit if values don't decrease, things like depreciation are recaptured at sale and you pay some tax then but if you're in a high quality market, buying and holding for the long term, etc it may still make sense to consider below the 8% CoC level if your confident in your numbers and have appropriate reserves.

Don't change your principles and strategy just because the local market won't work, change your market to fit your principles and goals!  

@Anthony Rosa - I'm still in the learning phase and working through deals to define my cash flow objectives.

Your mortgage payment is principle and interest, and should be fairly easy to calculate.  

We’re planning to aggressively pay down principle so we can access our equity quicker and use it for another purchase.
