Understanding Adjustments on Closing Day

In Nova Scotia, standard real estate transactions require financial adjustments to be made between the buyer and the seller on the closing date. As outlined by the Nova Scotia Real Estate Commission (NSREC) standard Agreement of Purchase and Sale, these adjustments ensure that each party only pays for the property expenses corresponding to the exact number of days they own the home.

Proration (or apportionment) applies to items like municipal property taxes, condominium fees, rental income, and—very commonly in Nova Scotia—leftover heating oil. To calculate these accurately, you must understand the foundational rules of Nova Scotia closing adjustments.

The Golden Rules of Nova Scotia Prorations

• The Buyer Owns the Closing Day: In standard Nova Scotia practice, the buyer is legally responsible for the property's expenses (and entitled to its income) starting at 12:01 AM on the day of closing. The seller's responsibility ends on the day before closing.
• The 365-Day Year: Unless a leap year is specifically noted in the exam question, always use 365 days for annual calculations.
• Prepaid vs. Accrued: If a seller has paid an expense in advance (prepaid), the buyer must credit the seller. If an expense is accumulating but hasn't been paid yet (accrued), the seller must credit the buyer.

Step-by-Step Proration Calculation Method

When you encounter a proration question on the Nova Scotia Real Estate Exam, avoid panicking by following this reliable four-step method:

1. Determine the Total Amount and Period: Identify the total cost of the bill and the exact timeframe it covers (e.g., an annual tax bill or a monthly condo fee).
2. Calculate the Per Diem (Daily) Rate: Divide the total amount by the number of days in the period. Always carry your decimals to at least four places during the calculation to avoid rounding errors, rounding to the nearest cent only at the final step.
3. Count the Days: Determine exactly how many days belong to the seller and how many belong to the buyer. Use the "knuckle method" or memorize the days in each month to ensure accuracy.
4. Multiply and Assign the Credit/Debit: Multiply the per diem rate by the number of days the buyer or seller is responsible for. Finally, determine who owes whom based on whether the bill was prepaid or is in arrears.

Common Proration Scenarios in Nova Scotia

Let's look at how this step-by-step method applies to the specific scenarios you will see on your exam and in your career.

1. Municipal Property Taxes

Property taxes in municipalities like the Halifax Regional Municipality (HRM) or Cape Breton Regional Municipality (CBRM) are billed annually or semi-annually but are always calculated on an annual basis for closing adjustments.

Scenario: A property in Dartmouth has an annual property tax bill of $3,650. The seller has already paid the entire year's taxes. The closing date is June 15th. How much does the buyer owe the seller on closing?

• Step 1: Total amount is $3,650. The period is 365 days.
• Step 2: Per Diem Rate = $3,650 ÷ 365 = $10.00 per day.
• Step 3: Count the days. The seller owns the property from January 1 to June 14.
  Jan (31) + Feb (28) + Mar (31) + Apr (30) + May (31) + June (14) = 165 days.
  The buyer owns the property from June 15 to December 31.
  365 total days - 165 seller days = 200 buyer days.
• Step 4: The seller prepaid for the whole year. Therefore, the buyer must reimburse the seller for the buyer's share of the year (200 days).
  200 days × $10.00 = $2,000.

Result: The buyer credits the seller $2,000.

2. Heating Oil Adjustments

Unlike many other provinces, a significant percentage of homes in Nova Scotia rely on oil heating. It is standard practice to adjust for the remaining oil in the tank on closing day. Note: In Nova Scotia, Harmonized Sales Tax (HST) at 15% must be added to the value of the remaining oil.

Scenario: A home in Truro closes on October 1st. The seller has the oil tank dipped the day before closing, revealing 400 liters of oil remaining. The current market price for heating oil is $1.25 per liter. What is the adjustment?

• Step 1 & 2: Value of the oil = 400 liters × $1.25 = $500.00.
• Step 3: Add 15% HST (Nova Scotia rate). $500.00 × 0.15 = $75.00.
• Step 4: Total value = $575.00. Because the seller is leaving this fuel for the buyer to use, the buyer must pay the seller for it.

Result: The buyer credits the seller $575.00.

3. Rental Income Adjustments

If you are dealing with a tenant-occupied property, rent is usually paid in advance on the first of the month. If the property closes mid-month, the seller has collected rent for days the buyer will own the property. This ties heavily into property management basics.

Scenario: A duplex in Sydney generates $1,500 in rent per month, paid on the 1st. The closing date is September 21st. Who owes whom, and how much?

• Step 1: Total amount is $1,500. The period is September (30 days).
• Step 2: Per Diem Rate = $1,500 ÷ 30 = $50.00 per day.
• Step 3: The buyer owns the property from September 21 to September 30 (10 days).
• Step 4: The seller collected the full $1,500 on Sept 1st. The seller must give the buyer the rent for the buyer's 10 days.
  10 days × $50.00 = $500.00.

Result: The seller credits the buyer $500.00.
