Q

Calculate the sales price based on the desired net amount

A
  1. Calculate rem rate including taxes as a %
  2. Calculate net desired by seller as a %
  3. Calculate sales price in $

Example:
1. Seller wants net $260k:
2. 5% (rem) x 1.14975 = 5.74875%
3. 100% - 5.74875 = 94.25125
4. Rule of 3: 100*260000/94.25125 = $275858.41

Rules for choosing mortgage loan rate needed for calculation purposes

A
  • Conventional
    • Higher of contractual interest rate + 2%, or 5 yr benchmark rate from Bank of Canada (25-30y amort)
  • Insured
    • 5yr benchmark, 25yr amort
16
Q

Calculation of Amortization Coefficients

A
  • Gross Debt Service Ratio (GDSR)
    • 32% of gross income can go to payment, taxes and heating
  • Total Debt Service Ratio (TDSR)
    • 40% of gross income can go to payment, taxes, heating and other debts
17
Q

Calculate Loan Amount based on income

A
  1. Verify downpayment and make sure client can pay closing costs another way
  2. Calculate the debt ratio (this is when you choose the mortgage loan rate as well
  3. Find maximum monthly pmt using GDS/TDS
  4. Find max loan amount (PV) using TVM solver
  5. Determine max amount client can spend on property
    a. PV at this stage is not the final amount as it includes the amortized insurance premium (if insured) based on LTV
  6. Consult a mortgage lender
18
Q

Open vs Closed Mortgage

A

Open:
- No repayment penalty
- Higher rate
- Shorter term

19
Q

Advance repayment penalty calculation

A

Higher of:

1- 3 months of interest on advance repayment amount at contractual rate

2- Interest differential (difference between loan rate and bank’s rate)

    - Determine balance due at the time of repayment
    - Determine the balance at the stipulated term of the agreement
    - Update the balance at term and the payments remaining in the stipulated term at the current bank rate
    - Subtract balance due at time of advance repayment from PV amount
