Not knowing your precise balance but guessing from your payment you have roughly a 150-200k loan,  and even if you could get the appraisal with enough equity to refi straight across (same balance) and drop the MI you'd be paying about the same.  

@Edita D.What precisely do they mean by garage trim calking?

In sharing this, my motivation is not to compare this investment opportunity to any other ... it is to:Give new folks an unambiguous stick in the sand to calibrate opportunities they run across.To encourage all of us, when discussing numbers, to use precise language.

I have never paid it off precisely how I thought I would, but I was aware that I needed to try to get it paid of long before it converted to an amortizing loan.

My apologies if I wasn't that precise when it comes to Progreso but the way I was talking about included the nearby towns as well as Yucalpeten.4.

Are there percentages I could use to estimate individual expenses, for when I want to get more precise than assuming 50% of rent will be expenses.

should have been more precise my apologies, single family homes to fix and flip!

So, it should in theory be more precise to predict the appraisal value up front.

As the others have noted, you'll want more precision in your estimate of each expense as your working toward the offer. 

I would suggest which  I use daily online title calculators provided by local title companies in the market which would be precise since title is regulated and your escrows are usually consistent in the Philly Market depending on due dates of taxes and HOI.Let me know if you have any questions.Regards,Joe Scorese
