Common questions

Is it always better to buy than to rent?+

No. Buying builds equity and can be cheaper over a long horizon, but it carries large upfront and ongoing costs - deposit, transaction fees, maintenance, insurance, and property tax - and ties up capital and mobility. Renting is often the better financial choice over shorter periods, in expensive markets, or when you value flexibility, especially if you invest the money you would have sunk into a purchase. This tool compares both paths honestly rather than assuming buying wins.

What is the 'invest the difference' comparison?+

A fair rent-versus-buy analysis does not just compare rent to a mortgage payment; it assumes the renter invests the money a buyer would have spent on the deposit and on the extra costs of owning. Over time those invested savings can grow substantially, which is why renting and investing can beat buying in some scenarios. Ignoring this makes buying look better than it really is.

What is the break-even time horizon?+

Because buying front-loads large costs, there is usually a number of years you must stay put before ownership overtakes renting financially - the break-even point. Sell before then and the transaction costs can wipe out any gain. If you are unsure whether you will stay long enough, renting is often the lower-risk choice. This calculator helps you find roughly where that break-even falls for your inputs.

Does this capture everything about the decision?+

It captures the main financial drivers, but a home is also a lifestyle and emotional decision - stability, freedom to renovate, or the flexibility to move for work. The numbers should inform the choice, not dictate it. Use the output to understand the financial trade-off, then weigh it against what matters to you personally.
