Why We Open-Sourced Our Secret Sauce

Most real estate companies hide their formulas. We publish ours. Here's why.

Our Offers Hold Up to Scrutiny

Companies hide formulas when their numbers don't make sense. Ours do. We have nothing to hide because our math is defensible.

Trust is the New Margin

In a market flooded with "we buy houses" scams, verifiable transparency is a competitive advantage. Sellers can confirm we're legitimate.

The Industry Should Be Better

If more companies showed their math, sellers would benefit. We're MIT licensed because transparent valuations should be standard, not secret.

Here's a preview of what's inside the package

example.ts
import { calculateOffers } from '@lhbusa/valuation-engine';

// Calculate all offer options for a property
const property = {
  arv: 350000,        // After Repair Value
  repairCost: 25000,  // Estimated repairs
  market: 'standard'  // Market conditions
};

const offers = calculateOffers(property);

// Returns transparent breakdown for each option:
// - Cash Offer (immediate, ~75% ARV)
// - BKPP™ Partnership (88% ARV, we handle repairs)
// - Traditional Listing (net after all fees)

console.log(offers.bkpp.sellerNet);  // $308,000

Cost to get the home market-ready
ARV (After Repair Value)
What your home would sell for on the open market if all repairs and updates were completed. Think of it as your home's "best case" sale price.
Estimated Repairs
The cost to fix everything a buyer would expect — roof, HVAC, cosmetic updates, etc. Our estimates are based on local contractor rates and comparable sales. Call us for a personalized estimate.
Agent Commission
The fee paid to real estate agents, typically 5-6% of the sale price, split between buyer's and seller's agents.
Closing Costs
Fees for title insurance, escrow, recording, and transfer taxes. Typically 1-3% of sale price for sellers.
Buyer Concessions
Credits buyers often negotiate to cover their closing costs or repairs found during inspection. Common in buyer's markets.
Holding Costs
Money you spend while waiting to sell — mortgage payments, property taxes, insurance, utilities, HOA fees. Adds up fast if your home sits on market.
BKPP™ Payout Rate (88%)
The percentage of ARV you receive through our Bee's Knees Partner Program™. We handle repairs, closing costs, and risk — you get certainty and more net proceeds than a traditional sale.
Cash Offer Rate (75%)
The percentage of ARV for an immediate, as-is cash sale. Lower than BKPP™ because you're trading equity for speed and certainty — close in 7-14 days, no repairs, no showings.
About our estimates: Repair costs vary by market, condition, and scope. The numbers above use regional averages. For a personalized estimate based on your specific property, call 1-800-858-0588 or request an offer.
