Note
This is a simplified projection model. It compounds the growth, cost and return rates you enter at a constant annual rate and amortizes mortgages on a standard fixed-rate annuity; real property markets, rents, interest rates, vacancy, maintenance and running costs move irregularly and can fall as well as rise. Taxes are applied only as the flat rate and allowance you enter: stamp duty and other transfer taxes are usually banded, capital gains relief, principal-residence exemptions, rental-income tax, depreciation and allowable expenses vary by country and by your circumstances and are not modelled here. Transaction, legal, letting and selling costs are taken as the percentages you supply. Baseline comparisons hold the alternative flat and ignore what else the money might have done. These results are general information, not investment, mortgage, tax or legal advice: consult a qualified professional before committing to a property decision.

What two things actually build home equity over time?+
Equity grows from paying down the mortgage principal (amortization) and from any increase in the property's market value (appreciation). Early in a mortgage, principal paydown is slow because most of the payment covers interest, so appreciation often contributes more to equity growth in the early years.
Why does my equity grow faster in later years of the mortgage?+
As the loan balance shrinks, a growing share of each fixed payment goes to principal rather than interest, so the amortization component of equity growth accelerates over the life of the loan even though the payment itself doesn't change.
Does the projection assume property values only go up?+
That depends on the appreciation rate you enter. Setting it to zero isolates the equity you'd build from mortgage paydown alone, which is a useful, more conservative baseline if you're unsure about future price movements in your market.
How does an extra payment toward principal affect the path?+
Extra principal payments accelerate amortization directly, shrinking the balance faster than the schedule requires and increasing equity immediately by the amount paid, plus reducing the interest charged on all future payments.
Is home equity the same as cash I can access?+
No — equity is a paper value based on the estimated market price minus what's owed; accessing it requires selling the home or borrowing against it (such as a home equity loan or line of credit), both of which have their own costs and conditions.
