Real estate exam math: seven items, and how they are set

Real estate maths has a reputation out of all proportion to its weight. On the national portion it is seven of eighty scored items — tied for the smallest content area on the exam. What makes it feel harder than it is has almost nothing to do with the arithmetic.

What the seven items actually cover

The published outline breaks the maths area into seven sub-areas of one item each, which tells you something useful: you will very likely see one of each rather than three commission problems and nothing else.

  • Property area — square footage and acreage
  • Property valuation — CMA figures, net operating income, cap rate, equity, assessed value
  • Commission and compensation
  • Loan financing costs — interest, loan-to-value, points, amortization
  • Settlement and closing costs — down payment, PITI, net to seller, prorations, transfer tax
  • Investment — return, appreciation, depreciation
  • Property management and budget calculations
All seven are classified as application or analysis rather than knowledge. There is no item that simply asks you to state a formula.

The two constants nobody hands you

The candidate handbook says plainly that this information is not available at the test centre and should be memorised. The acre figure in particular is load-bearing: every area question routes through it.

A question that needs a proration will tell you whether to use a 360-day or a 365-day year, and whether the day of closing belongs to the buyer or the seller. You are not expected to guess the convention.

  • 43,560 square feet in an acre
  • 5,280 feet in a mile

Where the marks are actually lost

Almost never in the arithmetic. The recurring errors are errors of set-up, and there are four of them worth rehearsing until they are automatic.

The wrong base. A point is one percent of the loan, not of the price. A profit percentage is measured against what was paid, not against what it sold for. An appreciation percentage divides by the original value, not the new one.

The skipped step. A property tax question with an assessment ratio in it is testing exactly one thing: whether you apply the mill rate to the assessed value rather than the market value. The ratio is in the question because skipping it is the mistake.

The wrong period. Taxes and insurance arrive as annual figures and payments are monthly. A gross rent multiplier conventionally uses monthly rent and a gross income multiplier uses annual income — a factor of twelve between two things named almost identically.

The wrong direction. On a settlement statement, every proration produces a debit for one party and a credit for the other. Work out who has had the use of the money and who ought to end up with it before you write anything down.

A working method for the day

  • Read the last sentence of the question first. It tells you what is being asked for, which determines what you should be extracting from the rest.
  • Write down what is given with its units attached. Most errors of period announce themselves here.
  • Identify the base before you calculate anything: percentage of what?
  • Do the arithmetic. Then check the answer against common sense — a commission larger than the deposit, a tax bill the size of a mortgage payment, an acre that came out as forty.
  • Move on. Seven items is not where a paper is won, and the time spent agonising over one of them is time taken from the sixteen contracts and agency items that are.

Frequently asked

How much math is on the real estate exam?
Seven of the eighty scored items on the national portion — under ten percent. Your state portion may add a small number more.
Can I use a calculator on the real estate exam?
Policy is set by the state and the vendor. California, for instance, permits a silent, battery-operated, pocket-sized, non-programmable calculator with no print-out and no alphabetic keyboard. Check your own state’s candidate handbook rather than assuming.
How many square feet are in an acre?
43,560. It is one of the two constants the handbook says are not supplied at the test centre.
Do I need to memorise an amortization formula?
No. The items in this area ask you to compute things like a first month’s interest, a loan-to-value ratio or the cost of points — arithmetic on given figures, not the amortization formula itself.
