Pair this drill with the Advanced module lesson on real estate math. PSI-style items often look like word problems: find the unknown (sale price for net to seller, monthly interest-only payment, annual tax from mill rate, etc.). Write the formula, then plug numbers — avoid mental math under time pressure.
Patterns to automate
- Commission and points = percentage of price or loan amount.
- Area = length × width; acres = 43,560 sq ft.
- Tax = assessed value × (rate per $100) ÷ 100, or mills ÷ 1,000 × assessed value — read the problem's unit carefully.
- Value from income = NOI ÷ cap rate; LTV = loan ÷ lesser of price or appraised value (use what the stem gives).
- Prorations: match the calendar the problem states (360 vs. 365) and whether the party owes or receives.
If a number looks 'too clean' on the exam, double-check you used gross vs. net, annual vs. monthly, and the correct base (sale price vs. loan amount).
