Condo Cash Flow Calculator
Calculate monthly cash flow for a condo rental after mortgage, HOA, taxes, and insurance.
By True Condo Cost editorial team · Editorial standards
Positive cash flow depends on rent growth, fee stability, and financing terms. HOA special assessments can wipe out a year of profit overnight.
Stress-test rent and expense assumptions before counting on passive income.
Your numbers
What this means
Positive cash flow of $0.00/mo before taxes and capital events.
Assumptions and limitations
- Mortgage entered as total P&I; does not model special assessments.
Frequently asked questions
- Should HOA be counted as expense for rentals?
- Yes. HOA is an operating expense that reduces net cash flow.

Most buyers model HOA, insurance, and assessments in separate passes.
Cash flow fails on HOA growth, not mortgage alone
Illustrative rental: $2,400 rent − $1,950 PITI+HOA − $200 vacancy/maintenance = $250/month—until HOA rises $90 and insurance $40 next year and cash flow goes negative without a rent bump.
Include assessment reserves in expenses
Landlords who ignore special assessment risk understate expenses. Add a monthly set-aside when percent funded is under 40% with roof age past 20 years.
Condo Cash Flow: one scenario to try
Inputs: $2,600 rent − $2,050 expenses (PITI+HOA+mgmt) − $200 vacancy → $350/month. Raise HOA $95 and insurance $35 next year without a rent bump and cash flow falls to $220/month.
Condo Cash Flow: what stays off the spreadsheet
It does not pull market rent comps or management quotes.
It does not reserve for special assessments—add a monthly set-aside when percent funded is low.

When to use this calculator
- You want monthly rent minus expenses on a specific condo
- You are deciding whether to hold or sell a rental unit
- You need a simpler view than full ROI over multiple years
Inputs you need
- Monthly rent and vacancy allowance
- PITI, HOA, insurance, and management fees
How to interpret the result
- Negative cash flow may still work for appreciation plays—know your hold reason
- Add assessment reserve when percent funded is low
What this calculator does not know
- Live tax bills, insurance quotes, or HOA budgets from any database
- Lender approval, HOA questionnaire results, or project eligibility
- Future HOA increases unless you change the inputs yourself
- Tax deductions or depreciation
- Sudden special assessments unless you add a line
Documents to verify before relying on the estimate
- HOA budget and most recent financial statements
- Reserve study and percent-funded summary
- Master insurance declarations and renewal summary
- County property tax estimate for the unit at your offer price
- HO-6 insurance quote matched to master policy coverage
Educational estimates only. Confirm figures with association documents, county tax offices, and licensed professionals before you make an offer.
Frequently asked questions
- What if HOA raises fees after I buy?
- Run a second scenario with higher HOA. Rental cash flow can flip negative when master insurance renews or reserves are replenished.
Sources to verify before buying
Use this checklist during due diligence. Calculators help you plan; these documents tell you what a specific building actually costs.
- HOA budget and audited financials (or reviewed statements if the association is small)
- Reserve study with percent-funded and component schedules — often prepared under CAI / APRA standards
- Master insurance declarations: carrier, deductible, wind/hail sublimits, and coinsurance
- Board minutes covering the last two insurance renewals and any assessment votes
- Written special assessment notices and payment plans
- County assessor or municipal property tax estimator for the parcel (not a neighbor’s bill)
- HO-6 quote aligned to master policy gaps — confirm with your state Department of Insurance licensed agent
- Lender condo questionnaire or Fannie Mae / Freddie Mac project review status for warrantability
