Question 1190593
.
Avery and their family currently pay $1300 in rent per month. They want to know how much they could borrow 
for a mortgage if they wanted to make monthly payments that are the same as their current rent.
One possible loan is a 30-year mortgage with a 3.48% APR. How much could Avery borrow? (Round down to the dollar.)
How much would they pay back over the life of the loan?

Calculations in the post by @CPhill are not accurate.


<pre>
The formula, which should be used, is

    PV = {{{1300*(1-(1+0.0348/12)^(-360))/(0.0348/12)}}}.


Calculations should be done without making intermediate rounding.


Rounding is made at the end, ONLY.


The correct answer is 290,224.56 dollars, which can be rounded to $290,225.

Solved.

I used MS Excel in my computer, which works with 15 decimals after the decimal point,
providing a necessary precision.


It is equivalent to Google worksheet.



These are the best and the most appropriate calculators for such computing.
