Free Real Estate & Mortgage Tools

30 calculators for buying, selling, financing and investing in property

A house is the biggest number most people will ever sign for, and the industry does not make the math easy: principal and interest are only part of the payment, closing adds 2–5% on top, PMI comes and goes with your equity, and every loan program — FHA, VA, USDA, jumbo, ARM — prices differently. These tools decompose each of those decisions into inputs you actually know.

The category covers the full property lifecycle: affording and financing a purchase, owning it (property tax, escrow, HOA, equity), investing (cap rate, rent multipliers, flips, short-term rentals) and selling (commission, net proceeds). All calculations run privately in your browser — your income and home value are nobody's business but yours.

Refinance

Old loan vs new rate with closing costs included: monthly savings, the break-even month, and the lifetime-interest verdict that decides whether a refi is real savings. Open the Refinance →

Your tappable equity at 80–90% CLTV, the HELOC or equity-loan size it supports, and the payment on whatever you draw. Open the Home Equity →

PMI Removal

The month you hit 80% LTV to request cancellation, the 78% automatic date, and the appreciation shortcut — plus what canceling saves over the loan. Open the PMI Removal →

Escrow

Monthly escrow from your tax and insurance bills, the legal two-month cushion, and the shortage math behind the annual payment-change letter. Open the Escrow →

HECM payout estimates by age and rate — lump sum, credit line or tenure payments — with the fees and heir implications explained straight. Open the Reverse Mortgage →

ARM Calculator

5/1, 7/6 or any ARM structure projected through every reset with its caps applied — the payment today, the worst case, and the fixed-rate comparison. Open the ARM Calculator →

Interest-Only

The seductive IO payment and the amortization cliff after it — side by side with a standard loan's cost over the same life. Open the Interest-Only →

The true FHA payment — 3.5% down, 1.75% upfront MIP rolled in, annual MIP for the life of the loan — plus qualification rules without the jargon. Open the FHA Loan →

VA Loan

Zero-down VA payment with the funding fee applied by usage tier — and the dollar comparison against FHA and conventional that shows what the benefit is worth. Open the VA Loan →

USDA Loan

Zero-down USDA payment with both guarantee fees applied, next to FHA — plus the property-location and household-income tests that decide eligibility. Open the USDA Loan →

Jumbo Loan

Payments above the conforming line, the reserves and DTI jumbo lenders demand, and the piggyback strategy that sometimes avoids jumbo pricing entirely. Open the Jumbo Loan →

Renovation ROI

Cost-vs-value math for 14 common projects — what a kitchen, bath or roof project adds at resale, what it recoups, and when renovating beats moving. Open the Renovation ROI →

Land Loan

Land financing priced honestly by type — raw, unimproved or improved — with the 20–50% down payments, higher rates and shorter terms lenders actually require. Open the Land Loan →

Commercial

How to Choose the Right Tool

Buying? Start with Home Affordability to size the budget, the PITI Mortgage Payment calculator for the real monthly cost, and Closing Costs so the cash-to-close isn't a surprise; use the FHA, VA, USDA or Jumbo calculators if your loan fits a program. Already own? Refinance Savings, PMI Removal and Home Equity tools show what your equity can do. Investors should live in Cap Rate, Gross Rent Multiplier, Airbnb Income and Property Flip. Selling, the Commission and Home Selling Cost calculators estimate what you'll actually walk away with.

Frequently Asked Questions

Do the mortgage tools include taxes and insurance?

Yes — the PITI Mortgage Payment calculator explicitly adds property tax, homeowners insurance, PMI and HOA fees on top of principal and interest, which is what your lender's escrow payment actually looks like.

Where do the tax and fee rates come from?

Defaults reflect current national averages (noted on each tool), but every rate is editable — enter your county's property tax rate or your quoted insurance premium for a precise local answer.

Can these replace a lender's pre-approval?

No. They tell you what to expect and what to negotiate, but only a lender can commit to a rate. Walking in already knowing your DTI and PITI numbers puts you in a stronger position.

Is my financial information private?

Completely. Every tool runs locally in your browser — income, home price and loan details are never uploaded or stored.
