Every figure is an estimate - not a loan offer or financial advice. We'll pull your lot from public records and send numbers for your specific property.
How we calculate this
Net yearly rent = monthly rent × 12, minus the vacancy + expenses percentage.
Payback = build cost ÷ net yearly rent.
5-year return = ((net yearly rent × 5) − build cost) ÷ build cost.
Assumes a cash build - no loan, no property appreciation. Cost and rent defaults come from typical ADU projects and published guidance on unit sizes.
