After you find the value of the loan which would be 85% of 90% of the listing price, you'll need access to a time value of money calculator. I'm going to assume you have access to excel (easiest) or a TI 83 or something similar:
Value of the loan = $135,000*0.9*0.85 = $103,275
Here are the time value of money inputs - remember to adjust for the fact that we have monthly, not annual, payments:
N = 30*12 = 360
I = 9%/12 = 0.75%
PV = 103275
FV = 0
In excel we can use the function IPMT as follows:
=IMPT(.0075,1,360,103275,0)
The numbers entered are:
.0075 - Interest Rate
1 - The period we are looking for ie the first payment
360 - The total number of periods
103275 = PV
0 = FV
The function gives us 774.56 for the first interest payment. The remaining 56.41 is principal.
