10-year cash comparison

Deposit, closing costs and 120 months of owner cost: $1,046,280. 120 months of rent starting at $4,200 and rising 3% a year: $577,780.

OwnerCost assumptions: a 10-year period and 3% annual rent growth. This counts cash paid on the regular schedule only — extra principal is not included — and it ignores the equity you build, changes in the home's value, selling costs and what the deposit could earn elsewhere — so it does not say whether buying or renting is better.

What this includes

TDSR and MSR limit how much a bank may lend. CPF usage is not modelled. Do not treat the monthly figure as an in-principle approval.

How we calculate

Monthly rate = quoted nominal annual rate ÷ 12. Payment = P·i / (1 − (1 + i)^−n) over n months. Owner cost = instalment + insurance + maintenance fees. Cash to close = down payment + buyer's stamp duty + ABSD for your profile. The 10-year cash comparison uses two OwnerCost assumptions — a 10-year period and rent rising 3% a year — and counts cash paid on the regular schedule only (the extra-principal input is not included); it is not a buy-or-rent recommendation. Principal and interest are counted only until the loan is repaid (at most 120 months), so a term shorter than 10 years adds no payments after payoff; insurance, property tax and building or owners' fees continue for all 120 months; mortgage insurance stops when its own rule ends it and never after the loan does.
