Mortgage Calculator

The rent vs. own calculator above uses a fixed-rate amortizing loan, recurring carrying costs (tax, insurance, HOA, a maintenance reserve), rent that steps up each year, and a simple resale at the end of your comparison window—Explore Mortgage Calculator and how Madison and Realty AI connect IDX, CRM, and conversational lead capture for real estate teams.

Share the outputs as a conversation guide, not a verdict: align on assumptions first, then connect the dots to pre-approval, listing strategy, and how Madison can capture intent when visitors are already thinking about financing.

The left column establishes purchase economics: price, down payment, rate, term, closing costs as a share of the loan, and recurring ownership costs. Property tax and maintenance are expressed relative to purchase price so you can reflect typical local burden without needing a full tax bill.

The right column contrasts that with renting: starting rent, annual rent growth, expected appreciation (and sell-side costs on exit), plus an optional alternate return if the upfront dollars stayed invested instead of going to down payment and closing.

Real deals include items this sheet does not model end-to-end: PMI when down payment is under 20%, mortgage interest and property tax deductibility (where applicable), capital gains exclusion timelines, HOA special assessments, refi breaks, and moving or staging costs. Use the calculator to frame tradeoffs—then plug in lender numbers and tax guidance for a complete picture.

Start from the client’s actual rent and target neighborhoods, then adjust horizon to match how long they expect to stay. Anchor the conversation in three checkpoints:

• Year-one monthly cost: cash flow today versus renting.
• Cumulative cash out over the window: how much housing spend each path requires before any sale.
• Estimated net sale proceeds: rough equity after payoff and sell-side costs, before tax—so clients see why horizon length matters.

When numbers surprise people, slow down and revisit assumptions—especially appreciation, maintenance reserve, and rent growth. Small input changes swing long-horizon outcomes.

Visitors reading rent vs. buy content are often mid-funnel: they are comparing scenarios and may be willing to identify themselves if you answer quickly. Madison can greet them on the same pages as this tool, qualify urgency and price band, and push structured lead context to Follow Up Boss, Sierra, or your CRM—so the spreadsheet conversation turns into a booked conversation.

Start a free trial to put Madison on your IDX and content pages, or book a demo to map chat flows, compliance guardrails, and routing—for teams that want calculators like this to convert into qualified tours and applications.
