2SEVEN vital features of a mortgage Principal amountTerm to maturityInterest rateMonthly paymentAmortization schedulePointsFinancing Costs
3basic mortgage computations Using the Texas Instrument BA II Plus financial calculatorMortgage calculations require 4 of the six basic functionsNumber of payments (N)Interest rate per year (I/Y) (P/Y must be set to 12 for a standard mortgage)Loan amount (PV: present value equals about the loan)Monthly payment (PMT)Value of the mortgage at maturity (FV)Compute (CPT)
4basic mortgage computations B. Example: $200, % for 30 years, 1.5 points, $2000 closing costs.Points to Lender: .015 * 200,000 = $3,0003rd Party Loan Expense: $Total Costs: $5,000 ($ $2000)Net Loan proceeds to Borrower: 195,000C. Computing Monthly P&I1. N=360, I/Y = 4.5%, PV = 200,0002. CPT PMT: $
5basic mortgage computations D. Preparing the Amortization ScheduleUsing the AMORTization function (a second function of the PV key)Set the P1 and P2 values to 1: P1 = 1 , P2 = 1Press the down key Read the BALanceRead the PRiNcipalRead the INTerestpress the compute key (CPT): P1 and P2 values will increment to the next paymentrepeat steps starting with “c”
6Effective Borrowing Costs Third-party expenses: up-front expenses incurred by borrower but not paid to lender:Mortgage insurance premiumTaxes on the loanLender’s title insuranceAppraisalSurvey
7Effective Borrowing Costs B. Effect of 3rd party payments:Borrower net less at loan closing than lender’s actual net disbursement to borrowerResult?EBC > lender’s yieldC. Compute EBC to BorrowerN=360, PV = 195,000, PMT = 1,013.37CPT I/Y = % (vs 4.5% quoted rate)D. Compute Lender’s Yield (IRR)N=360, PV = 197,000, PMT = -1,013.37CPT I/Y = %
9Truth in Lending Act (FILA) Federal Truth in Lending Act requires disclosure of annual percentage rate (APR) on virtually all home mortgage loansAPR: Yield to maturity, after adjusting for:All loan finance chargesAll compensation to originating brokersAll other charges controlled by lenderPremiums for any required insuranceWhat inadequacy might you see in the APR as a measure of true borrowing cost?
10Effects of Loan Prepayment Suppose the previous loan is prepaid in 7 years. What are the effects on Lenders Yield and the EBC for Borrower?Loan Balance after 84 payments (7 * 12)AMORT: P1=84, P2=84: Bal = 98,524.09Lender’s Yield: N = 84, PV = 158,000, FV = (paying off loan balance. CPT I/Y = 4.75%EBC: PV = 156,000, CPT I/Y = 5.01%Bottom line: Prepayment actually increases Lender’s Yield and also EBC of loan.

13Effects of Additional Principal What happens when we add $100 to the monthly payment?PMT = , solve N =Lender’s Yield: I% = 4.71% (vs. 4.75%)EBC: PV = , I% = 4.92% (vs. 5.01%)
14Effects of Balloon Payments 15 year, 4.5% mortgage, with a $40,000 balloon payment (a partially amortized mortgage) with $1600 in points and $800 in losing fees.N=180, I/Y= 4.50, PV = 160,000: FV = -40,000 PMT = $1,067.99Lenders Yield: 4.63%EBC = 4.70%Total Pmt.: $232, →S Int = $72,238.55“Standard” Mortgage: S Int = $60,318.07
15Adjustable Rate Mortgage Worst Case: 1-year ARM, 30-year term$100,000 3%: PMT = $421.60Bal(12) = $97,912.24Reset interest rate after first year to 4%:N = 348, I/Y = 4.00, PV = , PMT = $475.834. Bal(12) = $96,085.525. Reset interest rate after second year to 5%:N = 336, I/Y = 5.00, PV = , PMT = $531.90B. If life-time cap = 5% - what can PMT rise to if rates go up 1% every year? $707.89
16Some Cost Saving Strategies If you don’t plan to stay very longFind a mortgage deal with the smallest points (preferably none) and fees – which may result is a slightly higher rate.If you plan to stay for a long period of time, consider larger down payment or consider paying points to lower the contract interest rate.
17homework assignmentKey terms: Annual Percentage Rate (APR), Discount points, AmortizationStudy Questions: 1, 2, 6, 7, 10, 16Calculate the original loan size of a fixed-payment mortgage if the monthly payment is $1,146.78, the annual interest is 8.0%, and the original loan term is 15 years.For a loan of $100,000, at 7 percent annual interest for 30 years, find the balance at the end of 4 years and 15 years assuming monthly payments.
18homework assignment6. Give some examples of up-front financing costs associated with residential mortgages. What rule can one apply to determine if a settlement (closing) cost should be included in the calculation of the effective borrowing costs?7. A homeowner is attempting to decide between a 15-year mortgage loan at 5.5 percent and a 30-year loan at 5.90 percent. Assume the up-front costs of the two alternatives are equal. What would you advise? What would you advise if the borrower also has a large amount of credit card debt outstanding at a rate of 15 percent?
19homework assignment 10. Assume the following: Loan Amount: $100,000 Interest rate: 10 percent annuallyTerm: 15 years, monthly paymentsa. What is the monthly payment?b. What will be the loan balance at the end of nine years?c. What is the effective borrowing cost on the loan if the lender charges 3 points at origination and the loan goes to maturity?d. What is the effective borrowing cost on the loan if the lender charges 3 points at origination and the loan is prepaid at the end of year 9?
20homework assignment16. Assume that you have purchased a home and can qualify for a $200,000 loan. You have narrowed your mortgage search to the following two options:Mortgage ALoan term: 30 yearsAnnual interest rate: 6 percentMonthly paymentsUp-front financing costs: $5,000Discount points: 3
21homework assignmentMortgage B Loan term: 15-years Annual interest rate: 5.5 percent Monthly payments Up-front financing costs: $7,000 Discount points: 3 Based on the effective borrowing cost, which loan would you choose?
