About this site

ROI Property Tools is a free set of property guides and calculators for people who are new to property. You can ask a plain question, like “why is my wall damp?”, and get a plain answer, then go as deep as you want.

What you will not find here

No sign-up, no email capture, no pop-ups, no countdown timers and no “get a quote” buttons. Nothing is locked.

How we try to earn trust

  • Every page shows when it was last reviewed.
  • Claims and costs link to their sources, with the date we looked.
  • Costs are ranges, and we say what is missing. When sources disagree, we show both.
  • Where we have no reliable data, we say so instead of filling the gap.
  • Rules of thumb are labelled as rules of thumb.

Limits

This is general information for the United States. It is not professional, legal, financial or engineering advice, and it cannot see your property. For anything that might be structural, electrical, gas-related or a health risk, get a qualified local professional to look at it in person.

How the site is funded

ROI Property Tools is built to be a free resource for property owners and anyone trying to understand, maintain, improve, or make better decisions about a property. We aim to keep the core guides, explanations, calculators and educational resources freely accessible without requiring an account or payment.

The site may be supported through carefully selected advertising, affiliate relationships, or other transparent forms of funding that help cover hosting, research, development and ongoing maintenance. Funding should never change the underlying advice or the way information is presented. Where a commercial relationship could influence a recommendation, we will make that relationship clear.

Our goal is simple: keep the useful information open, practical and trustworthy.
