Answer:
Ans. your monthly payment, for 30 years is $9,257.51 if you buy a property worth $1,000,000 and you make a down payment of $100,000
Explanation:
Hi, first we have to change the fixed rate in terms of an effective monthly rate, which is 1% effective monthly (12% nominal interest/12 =1% effective monthly). After that, take into account that the property is going to be paid in 30 years, but since the payments are going to be made in a montlhly basis, we have to turn years into months (30 years * 12 = 360 months).
After all that is done, all we have to do is to solve the following equiation for "A".
![PresentValue=\frac{A((1+r)^{n} -1)}{r(1+r)^{n} }](https://tex.z-dn.net/?f=PresentValue%3D%5Cfrac%7BA%28%281%2Br%29%5E%7Bn%7D%20-1%29%7D%7Br%281%2Br%29%5E%7Bn%7D%20%7D)
Where:
A= Annuity or monthly payment
r= Rate (effective monthly, in our case)
n= Periods to pay (360 months)
Everything should look like this.
![900,000=\frac{A((1+0.01)^{360} -1}{0.01(1+0.0.1)^{360} }](https://tex.z-dn.net/?f=900%2C000%3D%5Cfrac%7BA%28%281%2B0.01%29%5E%7B360%7D%20-1%7D%7B0.01%281%2B0.0.1%29%5E%7B360%7D%20%7D)
![900,000=A(97.2183311)](https://tex.z-dn.net/?f=900%2C000%3DA%2897.2183311%29)
![\frac{900,000}{97.2183311} =A](https://tex.z-dn.net/?f=%5Cfrac%7B900%2C000%7D%7B97.2183311%7D%20%3DA)
![A=9,257.51](https://tex.z-dn.net/?f=A%3D9%2C257.51)
Best of luck.
