Thinking about buying a new home? We know sorting out your mortgage can feel like one of the trickiest parts, but it really doesn’t have to be. That’s where our mortgage calculator comes in.

It’s quick, easy and gives you a clear idea of what your monthly repayments could look like, so you can focus on finding your perfect home (and picturing yourself in it). 

What is the Strata mortgage calculator?

It’s an easy-to-use online tool that helps you estimate your mortgage repayments, based on a few quick questions. You don’t need to be a numbers expert, just fill in the boxes and let the calculator do the rest.

Here’s what you’ll be asked for:

  • Mortgage repayment type – Repayment means you pay back the loan and interest together, this is the most common option or Interest only where you pay just the interest, with the loan repaid later.
  • Mortgage purpose – For example: first-time buyer, home mover or buy-to-let.
  • Property value – The price of the home you’re looking at
  • Loan required – How much you want to borrow (not including your deposit)
  • Mortgage term – How long you’d like to repay the mortgage over

Once you’ve entered these, you’ll get see your Loan-to-Value also known as LTV, that’s the percentage of the loan compared to the property value. Then hit search and with seconds you’ll see a list of current mortgage deals for new-build homes that you might be eligible for!
