Calculating Return on Investment (ROI) accurately can make or break your house flipping success.
Quick ROI Formula for House Flipping
The basic ROI formula for house flipping is: (Net Profit / Total Investment) x 100.
Cost Components to Include:
- Purchase price
- Renovation costs
- Holding costs (mortgage, utilities, taxes)
- Selling costs (agent fees, closing costs)
- Insurance during renovation
- Permit fees
The 70% Rule in House Flipping
The 70% rule states that investors should pay no more than 70% of the After Repair Value (ARV) minus repair costs.
If a home’s ARV is $200,000 and needs $30,000 in repairs:
Maximum purchase price = ($200,000 × 0.70) – $30,000 = $110,000
Hidden Costs to Consider
- Unexpected repairs
- Market changes during renovation
- Contractor delays
- Financing costs
- Staging expenses
Time Value Considerations
Your ROI calculation should account for the project timeline, as longer holding periods eat into profits.
| Project Length | Additional Costs to Consider |
|---|---|
| 3-6 months | Standard holding costs |
| 6-12 months | Extended insurance, higher interest payments |
| 12+ months | Market risk, substantial holding costs |

Financing Impact on ROI
Different financing methods significantly affect your overall returns. Cash purchases eliminate interest but may limit investment volume, while leverage can multiply returns but increases risk.
| Financing Type | Impact on ROI |
|---|---|
| Cash Purchase | Lower total costs, slower scaling |
| Traditional Mortgage | Higher monthly costs, better leverage |
| Hard Money Loan | Highest costs, fastest closing |

FAQs
- What is the average ROI percentage to expect from house flipping?
The typical ROI for house flipping ranges from 10% to 30%, with experienced investors often achieving returns between 20% and 40%. However, this varies significantly based on location, market conditions, and renovation scope. - How do I calculate the ROI on a house flip?
ROI = (Net Profit / Total Investment) x 100. Net profit is the sale price minus purchase price, renovation costs, carrying costs, and selling expenses. Total investment includes purchase price, renovation costs, and all holding costs. - What is the 70% rule in house flipping?
The 70% rule states that investors should pay no more than 70% of the After Repair Value (ARV) minus repair costs. For example, if the ARV is $300,000 and repairs cost $50,000, the maximum purchase price should be $160,000 ($300,000 x 0.70 – $50,000). - What costs should I include when calculating total investment?
Include purchase price, closing costs, renovation costs, carrying costs (mortgage, utilities, taxes, insurance), marketing expenses, real estate agent commissions, and a contingency buffer (typically 10-20% of renovation budget). - How long should a profitable house flip take from purchase to sale?
A profitable flip typically takes 4-6 months from purchase to sale. Extended timelines beyond 6 months significantly impact ROI due to increased carrying costs and market exposure risks. - What is considered a good profit margin on a house flip?
A minimum profit margin of $30,000 or 20% of the total investment is generally considered good. However, urban markets may require higher margins due to increased costs and risks. - How do holding costs affect ROI in house flipping?
Holding costs typically reduce ROI by 2-3% per month and include mortgage payments, property taxes, utilities, insurance, and HOA fees. These costs can significantly impact profitability if the project extends beyond planned timeline. - What renovation improvements provide the best ROI?
Kitchen and bathroom renovations typically return 70-80% of investment, followed by exterior improvements (60-70%), and adding square footage (50-60%). Focus should be on improvements that bring the property up to neighborhood standards. - How does leverage (financing) affect ROI calculations?
Leverage can amplify ROI by reducing the cash investment needed. While a cash purchase might yield 20% ROI, using 75% financing could increase cash-on-cash return to 50% or higher, but also increases risk and costs. - What market factors most impact house flipping ROI?
Key factors include local market appreciation rates, housing inventory levels, average days on market, neighborhood comparable sales, local employment rates, and seasonal market fluctuations.
