C-RETS common mistakes
C-RETS · Understand the traps and how to avoid them.
Treating net operating income as gross rent minus operating expenses without deducting a vacancy and collection allowance, then using that inflated NOI to compute the cap rate or value.
Candidates carry residential habits into commercial problems, where gross scheduled income, effective gross income, and NOI are distinct steps. Marketing brochures often quote pro forma figures, reinforcing the shortcut.
What to do instead
Build every income statement in the same sequence: potential gross income, minus vacancy and collection loss, plus other income equals effective gross income; minus operating expenses equals NOI; then subtract capital reserves and debt service separately. Practice reclassifying line items (management fees, replacement reserves, leasing commissions) before calculating any ratio.
Applying the going-in cap rate to a projected future NOI, or dividing price by NOI that includes debt service, when asked for value or yield.
The cap rate formula is memorized as a single equation, so candidates plug in whichever NOI appears last in the question without checking whether it is stabilized, year-one, or levered.
What to do instead
Before calculating, label the NOI: is it year-one stabilized, pro forma, or after debt service? Use going-in cap rate on year-one NOI, terminal cap rate on forward NOI at sale, and cash-on-cash or IRR for levered returns. Write the label next to the number in scratch work so mismatches are visible.
Confusing equity dividend rate, cash-on-cash return, and debt coverage ratio, and reporting a DSCR as a percentage return.
All three come from the same loan and cash-flow data, and candidates under time pressure grab the first ratio that looks familiar rather than matching the metric to the question asked.
What to do instead
Memorize what each answers: cash-on-cash equals before-tax cash flow divided by equity invested (a return, expressed as a percent); DSCR equals NOI divided by annual debt service (a coverage multiple, expressed as a number like 1.25x). Drill converting between the two using a fixed loan constant.
Ignoring the time value of money by adding or averaging annual cash flows instead of discounting them, and treating a reversion as undiscounted.
Simple problems earlier in study materials use straight capitalization, so candidates default to addition when a multi-year hold with a sale appears.
What to do instead
Whenever a holding period longer than one year appears, set up a cash-flow timeline first: each year's cash flow, then the reversion (sale price minus selling costs minus loan balance). Discount each at the specified rate, and confirm IRR exceeds the discount rate only when NPV is positive.
Reading a market analysis question as a property-specific question and answering with subject-property data instead of submarket data.
Absorption, vacancy, and rent-growth questions look like the income analysis just practiced, and candidates reuse the same numbers without noticing the unit of analysis changed.
What to do instead
Classify the question before answering: is the subject the property, the submarket, or the metro? Market-level metrics (absorption, occupancy, construction pipeline, rent growth) come from inventory and demand data, not from one building's rent roll. Practice sorting a mixed set of data points into property, submarket, and metro buckets.
Mixing up absorption, net absorption, and vacancy, for example computing absorption as new construction minus demolition without accounting for space leased or vacated.
The terms sound interchangeable and textbook definitions vary slightly, so candidates rely on a vague memory rather than a precise formula.
What to do instead
Anchor on the operational definition: net absorption equals space occupied at the end of the period minus space occupied at the start, which also equals completed construction minus net change in vacant space. Test any answer by checking whether it reconciles beginning and ending occupancy.
Selecting a comparable set without adjusting for lease terms, tenant credit, or date of sale, and averaging unadjusted price-per-square-foot figures.
Comparable adjustment is time-consuming, and candidates assume recent sales are automatically comparable because they are nearby.
What to do instead
Screen comps on four axes before averaging: location, physical attributes, lease status and terms, and transaction date. Apply explicit adjustments for each difference and document them; if a comp requires large adjustments, weight it lower or exclude it and say why.
Mishandling prorations, expense stops, and closing-cost allocation in a transaction scenario, such as prorating rent to the wrong party or ignoring a tenant improvement allowance.
These are arithmetic-heavy details buried in narrative, and candidates focus on the headline price rather than the settlement statement.
What to do instead
Build a closing statement line by line: purchase price, credits and debits, prorated rents and operating expenses as of the closing date, security deposits transferred, and any outstanding tenant obligations. Assign each item to buyer or seller explicitly, then reconcile to the net proceeds figure.
Answering due-diligence and contingency questions by describing best practice generally rather than identifying the contractual consequence of a missed deadline or waived contingency.
Candidates know what due diligence involves but not how the purchase agreement allocates risk when a contingency lapses, so they pick the plausible-sounding procedural answer.
What to do instead
For each contingency (financing, physical inspection, environmental, title), memorize the default outcome if it is not satisfied or waived by the stated date, and who holds the deposit at that point. Read transaction questions looking for the trigger date and the remedy clause.
Confusing the roles and fiduciary duties of the parties in a commercial transaction, such as assuming a tenant representative owes the same duty to the landlord or that a dual agency disclosure resolves the conflict.
Residential training emphasizes disclosure forms, while commercial practice involves different representation structures, and candidates transfer the wrong framework.
What to do instead
Map the parties first: who represents whom, who pays whom, and what each engagement letter authorizes. Then apply the duty owed to the specific client, and treat dual or transaction brokerage as requiring informed written consent plus a defined scope of service, not just a signature.
