How This Calculator Works
Calculation methodology and assumptions
Total Project Cost = Purchase Price + Purchase Closing Costs + Rehab Budget + Total Holding Costs (monthly holding costs × months held). Net Profit = After Repair Value (sale price) − Total Project Cost − Selling Costs (agent commission and closing costs on the sale). ROI = Net Profit ÷ Total Project Cost, assuming the project cost is funded with cash or a hard money/rehab loan. Annualized ROI scales the ROI to a 12-month basis (ROI × 12 ÷ months held) so flips of different durations can be compared on equal footing.
How to Use This Real Estate Calculator
- 1
Enter the property price
Input the listing price or your offer amount. The calculator pre-fills your state's median home price as context. Consider whether the market favors buyers or sellers when evaluating price.
- 2
Set financing terms
Enter your down payment percentage, expected interest rate, and loan term. Real estate commissions (typically 5-6%, split between agents) are usually paid by the seller.
- 3
Include transaction costs
Factor in closing costs (2-5% of purchase price), home inspection ($300-$500), appraisal ($300-$600), and state-specific transfer taxes. These add significantly to the total investment.
- 4
Analyze the investment
Review total cost to acquire, estimated monthly carrying costs, and potential appreciation. Compare gross rent multiplier if evaluating as an investment property.
Example Calculation
Let's analyze a real estate purchase in a typical housing market.
Purchasing a 3-bedroom home for $375,000 with 20% down ($75,000). Closing costs at 3%: $11,250. Home inspection: $450. Total cash needed: approximately $86,700. Monthly mortgage (P&I at 6.75%, 30-year): $1,946. Add property taxes (~$310/month), insurance (~$150/month), and maintenance reserve (~$310/month). Total monthly cost: approximately $2,716.
Result: Total cash to close: $86,700. Monthly carrying cost: $2,716. If the home appreciates 3% annually, it gains $11,250 in year 1 — a 13% return on the $86,700 invested (leveraged return). Over 30 years with 3% appreciation, the home is worth $910K and the mortgage is paid off — $835K in equity from $86,700 invested. That's the power of leveraged real estate.
What Affects Your Results
Interest Rates
Every 1% rate change shifts purchasing power by approximately 10%. At 5% you can afford a $400K home; at 7% the same payment only covers $330K. Rate environment dramatically affects affordability.
Local Market Conditions
Your state's housing supply, population growth, and job market drive appreciation rates. Markets with job growth and limited supply appreciate fastest; declining population areas may stagnate.
Property Taxes
Annual property tax (0.3% to 2.3% of assessed value) is a carrying cost that never goes away — even after the mortgage is paid. Factor this permanent expense into long-term analysis.
Closing Costs
Title insurance, origination fees, attorney fees, recording fees, and transfer taxes typically total 2-5% of purchase price. These are sunk costs that take 2-3 years of appreciation to recover.
Tips & Best Practices
- Get a thorough home inspection — it's the best $400-$500 you'll spend. Inspectors find issues worth $5,000-$50,000 that affect your purchase price or walk-away decision.
- Understand your state's transfer taxes and recording fees before making an offer. These can add 0.1% to 2.6% to your transaction costs depending on location.
- In a buyer's market, negotiate closing cost credits from the seller (up to 3-6% of purchase price depending on loan type). This reduces cash needed at closing significantly.
- Don't waive contingencies to win bidding wars unless you truly understand the risk. Waiving inspection contingency on a $400K home to save a few thousand in negotiations can lead to $30K+ in undiscovered repairs.
- Look at price-to-rent ratio when evaluating: Price / Annual Rent. Under 15 = better to buy. Over 20 = renting may be smarter. Between 15-20 = depends on your time horizon and local market trajectory.

Our editorial standardsFrequently Asked Questions
What is a good profit margin on a house flip?
Many experienced flippers target a net profit of at least 10-20% of the After Repair Value, or use the "70% rule" (don't pay more than 70% of ARV minus rehab costs) as a purchase guideline. Margins compress in competitive or high-holding-cost markets.
What are typical holding costs on a flip?
Holding costs usually include hard money or bridge loan interest, property taxes, insurance, utilities, and HOA dues while the property is vacant and under renovation. These add up fast the longer a project takes, which is why holding period is one of the biggest levers in flip profitability.
Why does annualized ROI matter for flips?
A 20% ROI on a 4-month flip is a much better use of capital than a 20% ROI on a 12-month flip, even though the percentage return is identical. Annualizing lets you compare flips of different durations, and compare flipping against other annual-return investments like rentals or the stock market.
