How to Use This Rent vs Buy Calculator (Mini Guide)

What this calculator compares
It compares your estimated monthly cash cost of buying (mortgage + taxes + insurance + HOA + maintenance) against your monthly rent.
Think of it as a “monthly reality check” — not a full wealth-building model.
Who this is for
First-time buyers deciding if ownership fits their monthly budget.
Renters comparing true ownership costs (especially taxes/insurance/HOA).
Anyone relocating who wants a quick, realistic monthly estimate.
How to enter inputs (fast + correctly)
Rent: use the rent you’d pay for a truly comparable home/location.
Interest rate: use a rate you can actually qualify for today (not a hopeful future rate).
Taxes + insurance: don’t guess if you can avoid it — these two swing outcomes the most.
Maintenance: 1%/year is a common baseline; older homes often need more.
Quick example (sanity check)
If buying shows cheaper than renting, re-check taxes/insurance/maintenance first — most “buy wins” results come from underestimating those.
If buying is higher, it doesn’t mean renting always wins — it may still be worth it if you’ll stay long enough and value stability/control.
Next steps after you run it
If you might move within ~3 years, be extra cautious — transaction costs can overwhelm benefits.
