Professional Standards and Ethics

  • Fiduciary duties owed to a client are Obedience, Loyalty, Disclosure, Confidentiality, Accounting, and Reasonable care (OLD CAR); they are not owed to customers.

  • NAR Code of Ethics Article 1 requires REALTORS® to protect and promote the client's interest while dealing honestly with all parties to the transaction.

  • Ethics complaints are heard by local REALTOR® association professional standards committees; state licensing boards separately enforce real estate license law.

  • A Code of Ethics complaint must be filed within 180 days after the facts became known or reasonably should have been known.

  • Antitrust law bars competitors from agreeing on commission rates, splits, or market allocation; every commission is negotiable between one broker and one client.

  • Federal Fair Housing protected classes are race, color, religion, sex, national origin, familial status, and disability; state and local laws may add classes such as source of income.

  • RESPA Section 8 prohibits giving or receiving any fee, kickback, or thing of value in exchange for referral of settlement service business.

  • Procuring cause is the broker whose uninterrupted efforts began the series of events that produced the sale, supporting that broker's compensation claim.

Listing and Buyer Representation

  • Exclusive right to sell: the broker is paid regardless of who procures the buyer, including when the seller finds the buyer; it is the most common residential listing type.

  • Exclusive agency: the seller may sell unrepresented and owe nothing; the broker is paid only when the broker or a cooperating broker procures the buyer.

  • A net listing sets the broker's fee as proceeds above the seller's stated net, creating a fiduciary conflict; it is prohibited or restricted in many states.

  • A buyer representation agreement fixes the term, geographic scope, and compensation owed, converting the buyer from a customer into a client.

  • Dual agency requires informed written consent from both parties and limits the broker to neutrality and disclosure of material facts, with no advocacy for either side.

  • Designated agency assigns separate agents within one brokerage to the buyer and the seller; it is permitted in some states as an alternative to dual agency.

  • MLS cooperating compensation is a unilateral offer made by the listing broker, is negotiable, and is not fixed by MLS rule.

  • Agency disclosure is generally required at first substantive contact and before the buyer reveals confidential financial information.

Pricing, Valuation, and Market Analysis

  • A CMA compares the subject to recent closed comparables, typically 3-6 sales within the past 3-6 months, adjusting each comparable toward the subject.

  • Adjustment rule: add value when the comparable is inferior to the subject, subtract when superior; never adjust the subject property itself.

  • Months of inventory = active listings ÷ (closed sales in the period ÷ months in the period); roughly 6 months indicates a balanced market.

  • Absorption rate = homes sold per month ÷ active listings; a rising absorption rate signals a strengthening seller's market.

  • Cap rate = net operating income ÷ price; rearranged, value = NOI ÷ cap rate, which is the core income-approach formula.

  • Gross rent multiplier = price ÷ gross monthly rent; it is a quick screening tool that ignores vacancy, operating expenses, and financing.

  • Paired sales analysis isolates the contributory value of a single feature by comparing two otherwise similar closed sales that differ only in that feature.

  • Sales comparison is the primary approach for owner-occupied residential property, cost approach for new or special-use property, and income approach for rentals.

  • Keep individual line-item adjustments near or under 10% and net adjustments near or under 15% of the comparable's price; excessive adjustment weakens the comparable.

Contracts, Negotiation, and Transaction Management

  • Valid contract elements are offer, acceptance, consideration, capacity, and lawful purpose; real property contracts additionally require a writing under the Statute of Frauds.

  • Statute of Frauds: an agreement for the sale of real property is enforceable only if in writing and signed by the party to be charged.

  • A counteroffer terminates the original offer; the original offer cannot later be accepted unless the offeror revives it.

  • Earnest money is the buyer's consideration, held in escrow and credited at closing; a liquidated damages clause may allow the seller to retain it on buyer default.

  • Inspection, financing, and appraisal contingencies must be satisfied, waived, or released in writing by their deadlines or the contract may be terminated.

  • TRID requires delivery of the Closing Disclosure at least 3 business days before consummation; changes to the APR, loan product, or prepayment penalty reset the 3 days.

  • Time is of the essence: contract deadlines are strict, and extensions must be documented in writing before the deadline passes.

  • ZOPA is the overlap between the buyer's maximum and the seller's minimum; BATNA is each party's best alternative if no agreement is reached.

  • An escrow agent holds funds and documents and owes its duty to the escrow instructions rather than to either party individually.

Business Development, Finance, and Technology

  • LTV = loan amount ÷ the lesser of purchase price or appraised value; an LTV above 80% generally requires mortgage insurance.

  • DTI = total monthly debt payments ÷ gross monthly income; qualified mortgages generally cap the back-end ratio near 43%, and some programs allow up to 50%.

  • Maximum housing payment ≈ (gross monthly income × back-end DTI limit) − other monthly debt obligations.

  • Agent net commission = sale price × commission rate × agent split − desk fees, franchise fees, and per-transaction fees.

  • Cost per lead = marketing spend ÷ leads generated; cost per acquisition = marketing spend ÷ closed transactions produced by that spend.

  • Conversion rate = closed transactions ÷ leads × 100; tracking it by channel shows which marketing sources actually pay for themselves.

  • Section 1031 exchange: 45 days to identify replacement property and 180 days to close; capital gain is deferred, not eliminated.

  • Speed to lead matters: contact rates fall sharply after the first five minutes, so CRM routing and instant response alerts raise conversion.

  • Marketing ROI = (gross commission generated − channel cost) ÷ channel cost; a channel is kept only while ROI is positive.
