Overview

## What Mortgage IQ does

Mortgage IQ works out monthly mortgage payments and takes current interest rates from the Federal Reserve, so the estimate reflects published market rates rather than a typed-in guess.

Results come with charts that split principal from interest across the full term, and amortization schedules can be generated for any set of inputs. Purchase prices can be varied to see how the payment responds, which is the usual way of testing a budget before settling on a price range.

Example questions in the listing include the payment on a 500,000 dollar house, a monthly figure for a home in Florida, and what a zero percent VA loan works out to on an apartment.

### Who it is for

A buyer working out what a given purchase price means month to month.

### What stands out

Rates come from a live Federal Reserve feed instead of a static default the user has to supply.

## Where Mortgage IQ is listed

Mortgage IQ is listed in the ChatGPT apps directory only. Layer 3 Labs has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
