How does a rent vs buy comparison work?

Buying builds equity but ties up your deposit and adds transfer tax, maintenance, IPTU and condo fees. Renting keeps your deposit free to invest. The tool projects both paths over 10 years and compares your net wealth — home equity if you buy, versus your grown investment portfolio if you rent.

What costs does buying include in Brazil?

Upfront it adds ITBI transfer tax and notary/registry fees (roughly 3–5% of the price). Each year it adds IPTU (municipal property tax), condominium fees, maintenance and home insurance, on top of the mortgage instalments.

Why does the investment return matter for renting?

If you rent, the money you did not spend on a deposit and ownership costs can be invested. The comparison credits the renter with that portfolio's growth, so a higher assumed return makes renting more attractive, all else equal.

Is buying always better long term in Brazil?

Not necessarily. With high mortgage rates and modest appreciation, the ownership costs and interest can outweigh equity gains over 10 years, especially if investment returns are strong. The result is sensitive to your rate, appreciation and return assumptions — change them to test.

This Brazil rent vs buy calculator projects ten years of both choices and tells you which leaves you wealthier, using Brazilian mortgage rates, transfer taxes and ownership costs.

How it works

The tool simulates month by month and compares net wealth at year 10.

Buying: you pay the deposit, ITBI and fees upfront, then a fixed mortgage instalment plus yearly IPTU, condo fees, maintenance and insurance. The property appreciates each year, and you build equity as the loan amortises. Your buyer net worth is home value − remaining loan.

Renting: you pay rent (growing each year) and invest the money you would otherwise have spent on the deposit and on any month where ownership costs exceed rent. That invested pot grows at your assumed return. Your renter net worth is the portfolio value at year 10.

The cheaper path is the one that leaves you with more net wealth after ten years.

Example

A R$500,000 flat with a R$150,000 deposit at 10% over 30 years, versus renting an equivalent home for R$2,500/month — with 5% appreciation, 4% rent growth and an 8% investment return — can swing either way. High mortgage interest and ownership costs favour renting; strong appreciation favours buying. Adjust the inputs to see the tipping point.

Notes

The result is very sensitive to the appreciation and investment-return assumptions — test a range, not a single guess.
This is a financial model only; it ignores lifestyle factors like security of tenure and freedom to renovate.
Brazilian rents are often IGP-M or IPCA indexed; set rent growth to match your contract’s index.
