True monthly cash flow
Rent and other income less operating costs, reserves, and debt service — the number after everything, not before.
Rental property analyzer
Rental Property Analyzer: Cash Flow You Can Defend
A rental only works if it clears every month after the costs landlords forget. This analyzer prices vacancy, maintenance, management, and reserves into the monthly number so what you see is what lands in your account.
Free account required. Three complimentary analyses, then membership for continued access.
What paid memberships unlock
Complimentary analyses include a verdict, plain-language why, key numbers, top three risks, basic next step, offer guidance when possible, and a one-page summary. The advanced features below require Investor Plus or Investor Pro, as applicable.
Cap rate and cash-on-cash
Valuation against income and return against the cash you actually invested, side by side.
Vacancy and turnover pressure
How many vacant weeks a year the property can absorb before it stops paying for itself.
Long-hold projection
Five years of rent growth, principal paydown, and equity build shown as a chart, not a claim.
The costs that decide a rental
Vacancy, maintenance, and management are percentages of income for a reason: they scale with the property and they recur. Treating them as zero because the seller's numbers do is the most common way a rental purchase turns into a monthly loss.
Reserves matter just as much. A property that clears two hundred dollars a month and needs a four thousand dollar turnover has already spent twenty months of profit. The analyzer keeps that reserve in view so the cash flow figure survives contact with reality.

Questions
- Does it handle multi-unit rentals?
- Yes. Enter combined rent and expenses for duplexes through fourplexes, or use the multifamily page for larger properties.
- Can I model self-management?
- Yes. Set the management percentage to zero, though we recommend keeping a placeholder so the deal survives handing it off later.
- How much does it cost to try?
- Three complimentary analyses come with every free account.
