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.

Use the Fix & Flip calculator and see where you need to be in terms of a max price to pay and if that number is not acceptable to the seller, find the next deal.

Thank you for that amazing calculation and all the time you took to do that!

I recommend using a model that will show a % change annually for your rent income, expenses, ect calculating your NOI & potential sales price each year with growth
