Go ahead and have your agent do it.Obviously it's not going to be accepted by the bank's computer algorithm, but, hey, go get it out of your system. 

Thank you @Frank Jiang I am trying to do the numbers as "worst case scenario" I think this calculator is like you said there must be some algorithm  that's not calculating right, because even if i took off the "property tax" completely, the CoC comes out to be only 1.1% which is completely jacked.

Your mileage may vary, just make sure you know what it *should* be before you trust an algorithm to make those choices for you.

We eventually wrote an algorithm that looks at the entire MF market and gives us an indication of what deals might be viable...there is a lot to understanding how to evaluate properties and their performance...but most comes from experience...education.

Is that just because the way the algorithm is designed? 

Automated Value Models (zestimate, or anything else that posts a "estimated value") just won't do it; as the algorithm misses too many variables.

You may need to do the conversion from your currency to dollar $ to make sure everything works and no glitches within the algorithm throw things off.  

A good agent knows the market better then computer algorithms,  I have units rented right now that are literally renting $500 more then what Zillow thinks they should rent for. 

I have a Mathematics & Economics degree and got 4.0 GPA at college, but I made terrible investment decisions before even when I programmed a deep learning algorithm using probability and statistics to predict the stock market.

@David Russell  Credit score is only part of your fundability issue, it's how you are handling your money and the algorithms lenders use to determine if you are a good borrow.
