    -commission is split between brokers than it is split between the broker and the salesperson
  19. A seller listed his home for $200,000 and agreed to pay a full commission rate of 5%. The home sold four weeks later for 90% of the list price. The listing broker agreed to give the selling broker 50% of the commission. The listing broker paid the listing salesperson 50% of her share of commission, and the selling broker paid the selling salesperson 60% of his share of commission. How much commission did the selling salesperson receive?
    $2,700

    refer to T bar
  20. After deducting $5,850 in closing costs and a 5% broker's commission, the sellers received their original cost of $175,000 plus a $4,400 profit. What was the sales price of the property?
    $195,000

    STEP 1: Calculate the seller's net after commission:

    $175,000 (original cost) + $4,400 (profit) + $5,850 (closing costs) = $182,250 net after commission

    STEP 2: Calculate the rate after commission.

    100% (total rate) - 5% (commission rate) = 95% rate after commission

    STEP 3: Calculate the total sales price using the formula for total: part ÷ rate = total

    $185,250 net after commission (part) ÷ 95% rate after commission = sales price (total)

    185,250 ÷ 0.95 = $195,000

    chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%7B%24182%2C250%20%7D%7Btotal%3D%3F%2F95%25%3D0.95%7D&chs=280x84

    • To check, take 5% of the sales price, or, 
    • $195,000 x 0.05 = $9,750, which is subtracted from the sales price of $195,000, leaves the seller's desired net after commission of $185,250
  21. A profit is made when an item is sold for more than the purchase price. If an item is sold for less than the purchase price, there is a loss on the sale.

    Not that in the case of solving problems, profit is the part  and is larger than the total
    true
  22. A home was listed for $125,000. It sold for $123,200, which resulted in a 10% profit over the original cost. What was the original cost?
    $112,000

    STEP 1: Calculate the rate that the sale price represents.

    100% original cost + 10% profit = 110% sales price.

    STEP 2: Calculate the original cost using the formula for total: part ÷ rate = total.

    $123,200 sales price (part) ÷ 110% (rate) = original cost (total)

    $123,200 ÷ 1.10 = $112,000

    chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%7B%24123%2C200%7D%7Btotal%3D%3F%2F110%25%3D1.10%7D&chs=286x84

    accrued expense items
  55. What are three important key factors when computing prorations?
    -The seller owns the property on the day of closing; the seller is charged expenses for that day and gets income for that day. This is called prorating through the day of closing, which is a requirement of the Texas promulgated sales contract.

    -Prorations are based on either a statutory year or a calendar year.

    -The buyer pays the seller for prepaid expense items; the seller pays the buyer for accrued expense items. The party receiving the money "gets the credit"; the party paying the money is "debited".
  56. The seller owns the property on the day of closing, is charged expenses and receives income that day. This is required by the Texas promulgated sales contract.
    true: called prorating through the day
  57. What is the difference between a statutory year (aka banker's year) and a calendar year?
    • -statutory year (banker's year) based on a 360-day year, using 30 days in each month.

  58. When prorating, the buyer pays the seller for ___________ items and the seller pays the buyer for __________ items.
    • -prepaid expense items
    • -accrued expense items
  59. What are the three steps in prorating an item?
    1. The charge must first be broken down into yearly, monthly, and daily amounts, depending on the type of charge. Decide when type of year to use: statutory; a total monthly charge will be divided by 30, or calendar; the total monthly charge would be divided by the actual number of days in the month of closing.

    2. The prorated period is calculated using the actual number of months and days, using a calendar year or 30 days per month, using a statutory year.

    3. The monthly and daily amounts are then multiplied by the number of years, months and days in the prorated period to determine the accrued or unearned amount to be credited or debited at closing
  60. Interest on a mortgage loan is collected in arrears; each month's payment includes interest for the prior month. Therefore, it a seller's loan is assumed by the buyer, the seller owes interest for the portion of the month that he owned the property. The interest proration would be a _____ to the seller and a ____ to the buyer.
    • -debit
    • -credit
  61. A buyer purchases a home for $175,000 and plans to assume the seller's existing loan for $146,750 with monthly payments of $1449 at 10%. The closing date is set for August 18. Because interest on a mortgage loan is collected in arrears, the August 1 payments covered July's interest. Therefore, the seller has not yet made a payment to cover August's interest, and the seller will owe a portion of the interest to the buyer for the next house payment, how much would that be for a calendar year and a statutory year?
    Statutory

    Step 1: Find the dollars per day for interest: Calculate the amount of interest in the monthly payment, then divide that amount by 30 days.

    $149,750 x 10% x 1/12= $1222.916 interest for the month

    $1222.916 ÷ 30 days = $40.763 daily interest

    Step 2: Calculate the period for which the seller owes the buyer:

    18 days through the day of closing

    Step 3: Finally, multiply the daily interest amount by the number of days to be charged to the seller:

    $40.763 x 18 days = $733.73 prorated interest using a statutory year; a debit to the seller and a credit to the buyer.

    Calendar: same steps just different days in month.

    Step 1: Calculate the charge per day (31 days in August)

    $1222.916 ÷ 31 days = $39.448 daily interest.

    Step 2: Calculate period: 18 days

    Step 3: multiply the daily charge by the number of days:

  64. A sale is to be closed on September 17, and current real estate taxes of $1,200 are to be prorated accordingly. How much will the seller credit to the buyer with a statutory year and a calendar year?
    Statutory year

    Step 1: Determine the prorated cost of the real estate tax per month and day for the statutory year; 

    $1,200 annual taxes ÷ 12 mo = $100 taxes/mo

    $100 mo taxes ÷ 30 days = $3.333 taxes/day

    Step 2: The accrued period is 8 mo 17 days

    Step 3: Multiply the monthly and daily charges by the accrued period and add the totals to determine the prorated real estate tax;

    • $100 taxes/mo x 8 mo = $800
    • $3.333 taxes/day x 17 days = %56.661
    • $800 + 56.661 = $856.661 prorated taxes, using a statutory year. 

    Calendar year

    Step 1: A tax bill of $1,200 ÷ 365 days = $3.287/day

    Step 2: The accrued period from January 1 to September 17 runs 260 days (Jan 31 days, Feb 28 days)

    Step 3: $3.287 x 260 days = $854.62
