Question 1157355
use of a financial calculator will solve this easily.
my calcuclator is the texas instruments business analyst II.
inputs are:
house price is 157,000.
down payment of 23,000 means 157 - 23 = 134,000 must be financed.
inerest rate is 3.6% compounded monthly.
mortgage is for 30 years.
your inputs to this calculator will be:
present value = 134,000
future value = 0
interest rate per month = 5.6% per year  12 = .46666666...% per month.
number of months = 30 years * 12 = 360 months.
payments are made at the end of each month.
stick that in your calculator and have the calculator give you the monthly payment of 769.27 per month, rounded to the nearest penny.
there's an online calculator that does the same thing.
here's what the output of that calculator looks like.

the particular one that applies to your problem is shown below.
be sure to enter the inputs into your calculator exactly in the format shown.
otherwise you stand a good change of not getting the right answer.


ANNUITY FOR A PRESENT AMOUNT WITH END OF TIME PERIOD PAYMENTS

a = (p*r)/(1-(1/(1+r)^n))

a is the annuity.
p is the present amount.
r is the interest rate per time period.
n is the number of time periods.


your inputs to this formula would be as shown below.


(134000*.056/12)/(1-(1/(1+.056/12)^360))


your output will be 769.2658341 which is rounded to 769.27.
