How to Calculate ROI on a Foreclosure Property Flip
Direct answer
To calculate ROI on a foreclosure property flip, divide net profit by total cash invested, then multiply by 100. For a rental, divide annual net cash flow by total cash invested to get cash-on-cash return. Flip ROI depends on ARV, purchase price, rehab, holding costs, financing, taxes, title work, and selling costs. Rental ROI depends on rent, vacancy, operating expenses, debt service, reserves, and the cash you actually leave in the deal.
Worked example: foreclosure flip ROI
| ARV from closed comps | $230,000 |
|---|---|
| Purchase price | - $95,000 |
| Rehab budget | - $40,000 |
| Holding costs | - $12,000 |
| Financing costs | - $13,000 |
| Selling fees and closing costs | - $25,000 |
| Total cash invested | $124,000 |
Net profit: $45,000. If total cash invested is $124,000, ROI is 36.3%.

Use the full ROI formula
Net Profit = ARV - Purchase Price - Rehab Costs - Holding Costs - Financing Costs - Selling Fees. Total Cash Invested = Down Payment + Rehab Costs + Holding Costs + Financing Costs + All Closing Costs. Divide net profit by total cash invested, then multiply by 100.
Start with ARV from closed sales
After-repair value is the finished resale value supported by closed comparable sales. Compare similar properties in the same neighborhood and adjust for condition, size, and features. Do not use list prices. If the property needs heavy rehab, work backward from the finished sale price and make the repair math prove the spread.
Model foreclosure-specific holding costs
Foreclosure deals can sit longer than normal purchases because auction dates slip, title clouds delay closing, or rehab starts with less access than planned. Property taxes, vacant-property insurance, utilities, security, loan interest, HOA dues, and maintenance keep running while you wait. Use a worst-case timeline before you bid.
Do not forget friction costs
Vacant-property insurance can cost far more than a standard policy. Contractor contingency, permits, inspection fees, title insurance, HOA back payments, and days-on-market carrying costs can consume 5-10% of projected profit. Put those costs in the model before you call the deal safe.
For rentals, use cash-on-cash return
Rental ROI is usually cash-on-cash return: annual net cash flow divided by total cash invested. Net cash flow is rent minus vacancy, repairs, taxes, insurance, management, utilities paid by the owner, reserves, and debt service. Total cash invested includes down payment, closing costs, rehab, reserves, and any cash left in after refinance.
Use the calculators before you compete
DistressedDealRadar's free House Flip Calculator, Foreclosure ROI Calculator, and Rental Cash Flow Calculator run these inputs in seconds with no account, no login, and no credit card. Test different ARVs, rents, rehab budgets, financing costs, and holding timelines before you compete at auction or make an offer.
Compare different hold periods fairly
If two flips tie up cash for different lengths of time, annualize the ROI. A six-month project with 36% ROI annualizes to 72% before reinvestment friction. That does not make the deal risk-free, but it lets you compare capital velocity across short and long rehab projects.

Frequently asked questions
- What is holding cost and why does it matter in foreclosure ROI?
- Holding costs are property taxes, insurance, utilities, loan interest, security, and maintenance you pay while you own the property. In foreclosures, these can run longer because auction dates slip, title issues delay closing, or rehab takes longer than estimated. Even one extra month of taxes and insurance can cut ROI, so model the worst-case timeline.
- How does my state's foreclosure law affect ROI calculation?
- State foreclosure law affects timing, sale process, owner rights, title risk, and possible redemption issues. Longer judicial timelines can raise holding costs, while faster non-judicial processes can compress diligence windows. Use the state guides as an educational starting point, then verify current rules with official county or state sources or local counsel before you bid.
- Should I annualize my ROI if I flip properties over different timeframes?
- Yes. Annualized ROI helps compare a quick flip with a longer rehab project. If you hold a property for 6 months and net 36% ROI, the simple annualized ROI is 72% before reinvestment friction. Use it as a comparison tool, then check the absolute profit, risk, and cash tied up.
- How is rental property ROI different from house flip ROI?
- A flip has one main exit: sell the renovated property and compare net profit with total cash invested. A rental is ongoing, so investors usually track cash-on-cash return, annual net cash flow divided by the cash left in the deal. Use the flip ROI formula for resale projects and the rental cash-flow formula for buy-and-hold deals.
- Should I use the full property price or my cash invested for rental ROI?
- For cash-on-cash return, use the cash you actually invested: down payment, closing costs, rehab, reserves, and any cash left in after refinance. The full purchase price still matters for value and leverage risk, but it is not the denominator for cash-on-cash return.
- How do I estimate ARV (After Repair Value) for a foreclosure?
- Use comparable sales from recently closed properties in the same neighborhood, adjusted for condition, size, layout, and features. Do not use list prices. For heavy rehab, work backward from the finished resale value and verify that purchase price, rehab, holding costs, and selling fees still leave enough margin.
- What costs do most flippers forget when calculating ROI?
- Common misses include vacant-property insurance, contractor contingency, permits, inspection fees, title insurance, HOA back payments, utilities, security, and days-on-market costs between rehab completion and resale closing. These friction costs can eat 5-10% of projected profit if you leave them out.
