How the calculator works
- Price, deposit and mortgage rate, and whether the mortgage is repayment or interest-only.
- Rent, and the share of the year it might be empty.
- Running costs: management, repairs, insurance, property tax or rates, and any strata or service charges.
Example
A $350,000 home with $87,500 down at 7.74% over 30 years, renting for $2,400 a month, in its first year:
| A year | Amount |
|---|---|
| Rent collected (empty 4% of the year) | $27,648 |
| Property management | −$2,212 |
| Repairs and upkeep | −$3,500 |
| Insurance | −$1,800 |
| Property tax | −$3,850 |
| Mortgage payments | −$22,545 |
| Cash flow | −$6,259 |
That's −$522 a month. The gross yield is 8.2% and the net yield, after running costs but not the mortgage, 4.7%. On the $98,000 you put in (the down payment and buying costs), the cash return is −6.4%.
How the rent changes the picture, with everything else the same:
| Rent a month | Cash flow a month | Gross yield | Net yield |
|---|---|---|---|
| $2,000 | −$875 | 6.9% | 3.4% |
| $2,400 | −$522 | 8.2% | 4.7% |
| $2,800 | −$168 | 9.6% | 5.9% |
| $3,200 | $185 | 11.0% | 7.1% |
These are first-year figures, before tax and any change in the property’s value.
What the numbers mean
- Cash flow: rent collected, less the mortgage and every running cost. It’s what the property puts in or takes out of your pocket each month.
- Gross yield: a year’s rent as a share of the price. Quick for comparing listings, but it ignores costs.
- Net yield: rent after running costs, but not the mortgage, as a share of the price. Better for comparing properties, whatever the financing.
- Cash-on-cash return: cash flow as a share of the cash you put in. It shows what your own money earns.
Costs to budget for
- Property tax: varies a lot by state and county. See the property tax calculator for your state’s typical rate.
- Insurance: a landlord policy, rather than a homeowner’s policy.
- Repairs and upkeep: the calculator starts at 1% of the price a year. Older homes often need more.
- Management: the calculator starts at 8% of the rent collected. Managing it yourself saves this, but takes your time.
- Empty months: between tenants you pay the costs with no rent. The calculator starts at 4% of the year.
- HOA fees: if the home is in a community with a homeowners association.
Ways to improve the numbers
- Put more down: a smaller loan means a smaller payment, though your cash-on-cash return can fall.
- Compare rents nearby: check what similar homes rent for before you buy.
- Check the costs before you buy: a higher property tax or HOA fee can turn a positive cash flow negative.
- Plan for the long term: much of a rental’s return can come from paying down the loan and the home’s value rising, which isn’t guaranteed. When you sell, the gain is taxed: see the capital gains tax calculator.
