Development deals have more moving parts than flips. Freddie helps you model hard costs, soft costs, carry, and profit on any ground-up or major development project.
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.
Hard costs: land, site preparation, utilities, construction labor and materials. Soft costs: permits, architecture, engineering, legal, financing, insurance, marketing. Carrying costs: construction loan interest, property taxes during development, and overhead. Selling costs: agent commissions and closing costs.
Net profit = Sale/Rental Value minus Total Development Cost (hard costs + soft costs + carry + selling costs). Developer profit margins typically target 15-25% of total development cost or 10-20% of end value. Tighter margins require higher certainty on costs and exit values.
Construction loans fund development in draws — you request funds as you complete construction milestones. Interest is charged only on drawn amounts. Most construction loans convert to permanent financing at completion (construction-to-perm) or require refinancing with a take-out loan.
Renovation (fix and flip) improves an existing structure. Development starts from scratch — ground-up construction. Development involves more risk (entitlement, permitting, construction), higher capital requirements, longer timelines, and potentially higher returns. The tools and analysis methods differ significantly.
Entitlement and permitting: 3-18 months. Construction: 6-24 months. Lease-up/sell-out: 3-12 months. Total: 12-54 months for most residential development projects. Timeline varies enormously by project type, size, and jurisdiction. Every month of delay adds carrying costs.
As-of-right development complies with existing zoning and doesn't require special approvals. It's faster (no rezoning risk) and lower risk than projects requiring variances or rezoning. Savvy developers look for as-of-right opportunities where current zoning allows more density than what's built.
