Valuation Engine.
Your Turn.

There are thousands of companies that will make you a cash offer on your home.

Every single one of them uses some kind of formula to calculate what they'll pay you.

Not one of them will show you that formula.

Think about that. They're asking you to trust them with the biggest financial transaction of your life — and they won't tell you how they came up with the number.

We think that's insane.

So we did something about it.

The Code

This isn't a marketing gimmick. It's real, functional code that powers our actual offers:

// Install: npm install valuation-engine
import { calculateOffer } from 'valuation-engine';

// Every variable is documented. Every calculation is visible.
const offer = calculateOffer({
  estimatedARV: 350000,      // After-repair value
  repairEstimate: 25000,     // Documented line by line
  marketDaysAvg: 45,         // Local market data
  holdingCostMonthly: 2100,  // Carrying costs
  closingCosts: 8500,        // Title, transfer, etc.
});

// Returns: { offer: 285000, breakdown: {...}, margin: 0.12 }
// You see EXACTLY how we got there. No black boxes.

Every input. Every assumption. Every calculation. Published.

If you think we're wrong about something, you can literally open an issue on GitHub and tell us.

What We Published

The Wall of Silence

Now let's look at what the biggest players in our industry have published:

Why Won't They?

I've thought about this a lot. Here are the only explanations I can come up with:

1. The math is embarrassing. If sellers saw how much margin these companies build in, they'd never accept the offers. Hiding the formula hides the profit.

2. There is no formula. Some companies just lowball everyone and see who bites. Publishing that would be... awkward.

3. They don't want competition. If the methodology is public, anyone could build a better version. (Good. That's the point.)

4. They've never considered it. Transparency isn't part of the industry's DNA. No one does it because no one does it.

None of these are good reasons.

Why This Matters

Selling your home is probably the largest financial transaction of your life.

When you sell to a cash buyer, you're trading convenience for money. That's a legitimate trade-off — but you should know exactly how much money.

Without published methodologies, you're flying blind. You have no way to know if an offer is fair, aggressive, or predatory. You're trusting the buyer to be honest about a number that directly determines their profit.

That's not a market. That's a guessing game where only one side knows the rules.

We think sellers deserve better. We think transparency should be the baseline, not the exception.

So we went first.

Your move.
