Run your flip numbers in seconds. Freddie calculates profit, ROI, and every cost from purchase to closing so you never leave money on the table.
Dan White, 20-year fix-and-flip veteran in Northern Virginia, used FreeDealCalc to analyze a $130,000 wholetail opportunity in under 5 minutes. No spreadsheet. No paid software. Just Freddie.


"I've been flipping houses for 20 years and I built this tool because nothing free was actually good enough. Freddie does what I used to do with spreadsheets — but in seconds, for free, for every investor who needs it."
A buyer who purchases this property as a wholetail deal undertakes all renovation work at their own direction, cost, and risk. The seller makes no representations regarding property condition and all sales are as-is. Buyer is responsible for all due diligence, inspections, and compliance with local codes and regulations.
Flip profit equals after repair value (ARV) minus purchase price, minus rehab costs, minus holding costs, minus financing costs, minus selling costs. Our calculator automates all inputs and flags deals where margins are too thin to proceed safely.
The 70% rule says your all-in cost (purchase plus rehab) should not exceed 70% of ARV. On a $300K ARV property with $50K rehab, your max purchase price is $160K. It's a quick filter — use Freddie for precise deal analysis beyond the 70% rule.
Minimum capital for a basic flip is typically $20,000-$50,000 for down payment and rehab on a modest property with hard money financing. All-cash flips require full purchase plus rehab capital. Many investors use hard money (10-20% down) to preserve capital.
Most residential flips take 3-6 months from purchase to sale. Light cosmetic flips can close in 60-90 days. Major structural rehabs may take 6-12 months. Every extra month costs you in holding expenses — model different timelines in Freddie to see the impact.
Over-renovating for the neighborhood, underestimating rehab costs, overestimating ARV, extended hold times due to construction delays, and rising interest rates that compress buyer purchasing power. Freddie stress-tests all of these variables before you commit.
Ideally yes, or at minimum a reliable rehab estimate. Walking a property without understanding repair costs leads to bad MAOs and deal losses. Freddie can help you build a preliminary rehab estimate based on property condition and square footage.
