Thanks @David A LisowskiCan you recommend any articles or blog posts with detailed breakdown of how I should invest into STR and calculators for running the numbers? 

Once you add those adjustments I would then calculate your cash flow (income-expenses including your mortgage) and divide that by your down payment (which appears to be $44,000) to determine your "cash on cash" return.

I just want to know which calculator to use, as the rental calculator doesn't specifically say multifamily.

And how do you get a good number to calculate with if the costs changes dramatically throughout the year?

The lender should be using a form 1038 to calculate rental income for your investment properties.
