Want a calculator we don't have here? Send us a note — we'll consider adding it.

For agents who work with investors

A calculator on your own site shows investor visitors you speak their language before they ever call. It is a credibility piece: the embed collects nothing and reports nothing back to you, so use it beside your contact details, not instead of them. When a client is real, run their deals against their own Buy Box with TrueCap for agents.

Questions

Can I customize the calculator's look?

No. Inside the frame the calculator uses TrueCap's own styling, and the embed has no color, font, or branding settings. On your page, the snippet's inline styles only lay out the frame (full width up to 640px, a starting height that then adjusts to the calculator, no border, on its own line) and set the small gray text of the credit line under it.

Do I have to keep the 'Powered by TrueCap' credit?

The credit inside the calculator's footer is part of the embedded page, so it always shows. The snippet also puts a one-line 'Powered by TrueCap' credit under the frame, linking to that calculator's page on TrueCap. Keeping that line is the one thing we ask in return for a free, hosted calculator.

How does the embed affect page loading?

The iframe uses loading="lazy" and renders in its own document, which limits initial work in supporting browsers. Actual performance depends on the host page, browser, placement, and content-security settings, so measure the published page.

Can I track conversions from my embed?

Not through TrueCap: there are no per-site reports. Snippets copied from this page load the frame with no referrer, so loading the calculator does not tell TrueCap which page it sits on. The 'Underwrite a full property in TrueCap' link inside the calculator carries utm_source=embed, utm_medium=referral, and a calculator-specific utm_campaign, so TrueCap can count embed traffic in aggregate. No link carries your site's identity or anything a visitor enters.

What if the calculator changes?

The iframe loads the currently released TrueCap implementation, so reviewed updates appear without replacing the snippet. Snippets for the calculators listed on this page keep working. If we withdraw a calculator, a frame that still points at it shows TrueCap's 'page not found' page instead. Keep the credit line intact and check the embed as part of your own site checks.

Have a real estate audience?

Embed a calculator and write a short post around it. Your readers get a working tool without leaving your page, and we get a credit link back.
