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.
A lease option (also called rent-to-own) gives a tenant the right but not the obligation to purchase the property at a predetermined price within a set time period. The tenant pays an upfront option premium and monthly rent, with a portion of rent credited toward purchase.
Lease option profit combines three streams: upfront option premium (kept if tenant doesn't buy), monthly spread between rent collected and your mortgage payment, and backend profit if the tenant exercises the option (difference between option price and your cost basis).
Standard option premiums range from 1-5% of the purchase price. On a $250K home that's $2,500 to $12,500. Higher premiums filter serious buyers but reduce your pool of candidates. The premium is typically non-refundable and applied to purchase price.
Typical rent credits range from 10-25% of monthly rent. On $1,500/month rent, that's $150-$375 credited monthly toward purchase. Credits incentivize the tenant-buyer to exercise the option but reduce your monthly cash flow spread.
Main risks include tenant-buyer damaging the property, not maintaining it properly, or defaulting on rent. Also risk of property value declining below the locked option price. Require a substantial option premium, thorough tenant screening, and clear maintenance responsibilities in the contract.
Lease options typically generate higher monthly income, larger upfront premium, and attract more responsible tenants who have skin in the game. The downside is complexity, potential for legal disputes, and losing a good long-term tenant if they buy and move.
