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.
Frequently Asked Questions
What does a landlord calculator calculate?
A landlord calculator calculates rental income, operating expenses, net cash flow, cash-on-cash return, and cap rate for any rental property. It helps landlords determine if a property is profitable before purchasing and evaluate performance on properties they already own.
How do landlords calculate rental yield?
Gross rental yield equals annual rent divided by property value multiplied by 100. Net rental yield subtracts all annual expenses from rent before dividing. Always use net yield for real performance — gross yield ignores the costs that actually determine profitability.
What expenses should a landlord budget for?
Property taxes, landlord insurance (different from homeowners — $800-$1,500/year), property management (8-12% of rents), routine maintenance (budget $100-$200/month per unit), CapEx reserves ($150-$300/month per unit for roof, HVAC, appliances), and vacancy reserves.
How do landlords calculate how much rent to charge?
Start with comparable rentals in the same neighborhood for similar size and condition. Verify with free tools like Rentcast, Zillow Rental Manager, or Apartments.com. Price 5-10% below top of market to minimize vacancy. Freddie can pull local rent data to validate your pricing.
What is the 50% rule for landlords?
The 50% rule says operating expenses (excluding mortgage) typically run about 50% of gross rent. On $2,000/month rent, budget $1,000 for taxes, insurance, management, maintenance, and vacancy. Use it as a quick filter — always run precise numbers before buying.
How do I know if a rental property is worth buying?
The property should cash flow positively after all expenses including a mortgage, generate at least 8% cash-on-cash return, meet the 1% rule (monthly rent at least 1% of purchase price) in most markets, and score at least a B on Freddie's deal analysis before you make an offer.
