A different approach

Our co-buy calculator isn’t like other mortgage calculators. When you’re considering buying a home with someone, it’s nice to get an idea of what you can afford together. So we ask:

  • How much can each co-buyer chip in for the down payment?
  • What can each co-buyer pay monthly toward the mortgage?

From there, we estimate the home price you can afford. Pretty cool, huh?

What you could have in the future

We’re no good with a crystal ball, so instead we use your financial contributions and an estimate of your home’s appreciation rate to predict how each person’s investment will grow.

Before you get started

Let’s go over a few key points before you dive in.

We’ve started with some standard inputs.

Namely, a 30-year mortgage at the current average interest rate. Experiment with others!

Appreciation rate = value growth over time

This varies widely, so we’ve used a conservative estimate (5%). Try others and see what your future may hold!

Equity = value minus debt

Equity is the difference between the current value of your home and the amount you still owe on it.

Purchase Price

This estimate doesn't include property taxes, insurance, or closing costs. Your mortgage lender will take all of these into account, along with credit scores and existing debt, when determining the purchase price you can afford.


How your investment could grow

If your home appreciates at a rate of % per year, it will be worth $ in years.

Home equity
Your home's equity is the difference between its value and the amount still owed on the mortgage. Equity is divided among co-owners according to ownership percentage. For example, a co-owner with a 60% ownership percentage would be entitled to 60% of the home's equity.

Ownership percentages
Ownership percentages can change over time. For example, if you paid 20% of the down payment and closing costs, your initial ownership percentage would be 20%. If you then paid 60% of the mortgage payment each month, your percentage would grow. Learn more about this in the Pairadime Agreement 101.

Now that you have an idea of what you can afford, let’s make it happen.
