Mistake detector — Real Estate Investment Insights
What this scanner can see — and what it cannot
The detector looks at the sliders you set: vacancy too cute, capex too thin, inspection toggle off, management off while you still have a job. Those are real, boring ways to lose money. It cannot see a polybutylene plumbing surprise, a special assessment, a flood panel, or a tenant who has not paid in a city with a six-month eviction calendar.
Feed it unflattering numbers on purpose. If you have to ease vacancy to 2% to get a B, you already have the answer. For the items that should change the offer itself, use the twelve-check list rather than a letter grade.

How This Tool Works
This page, the Mistake Detector, helps you critically examine your real estate investment assumptions. It's designed to catch common, often overlooked errors in your deal parameters before they become costly mistakes. Instead of giving a simple 'yes' or 'no' on a property, this tool helps you identify where your initial numbers might be too optimistic, guiding you to a more realistic assessment.
To use it, simply adjust the sliders and toggles for your deal's Purchase Price, Monthly Rent, Vacancy Rate, CapEx Reserve, and whether a Property Inspection is done or if you're Using a Property Manager. As you change these inputs, you'll see the Net Cash Flow update. Once your numbers are set, click 'SCAN FOR MISTAKES' to see if the detector flags any of your assumptions as potentially risky.
This scanner looks at the numbers you provide. It's good at spotting if your vacancy rate is 'too cute' or your capital expenditure reserve is 'too thin.' A key tip: feed it unflattering numbers on purpose. If you need an unrealistic 2% vacancy to make the deal look good, you've found a potential issue. However, it cannot see physical problems like polybutylene plumbing or a special assessment. It's a teaching device for your inputs, not a substitute for professional advice.
