Before making an offer on a house

Before diving in headfirst with offers, there are a few steps to take that will put you in the strongest possible position. Proper preparation is what separates successful buyers from those who overpay or miss out.

Do your research

Define your requirements clearly

Consider what you want – location, size, condition, property type, and anything else important. Make a wish list of must-haves and nice-to-haves. Know what's non-negotiable and what you can be flexible on.

Ask yourself things like:

  • How many bedrooms/bathrooms do I need?
  • Urban or rural area?
  • Is it important to have a garage?
  • What kind of garden do I need?
  • Move-in ready or fixer-upper?
  • Will I need a home office?

Research local house prices

Research house prices in the same area using the Land Registry sold property tool or Zoopla. This gives you a sense of market rates and how much you may need to offer.

Look at both current asking prices and recently sold prices for similar properties.

Pay attention to how long properties are staying on the market in your target area. If houses are selling fast, you'll need to move fast and potentially offer closer to asking price. If they're lingering, you might have more negotiating power.

And if you're doing this for the very first time, check out our first-time buyers guide.

Being flexible widens options but stick to your non-negotiables.

Know your financial position

Figuring out your budget before making an offer is key. Unless you're a cash buyer, you'll likely need to secure a mortgage and understanding your financial position gives you confidence and credibility.

Get a mortgage in principle

Getting a mortgage in principle (MIP) gives a good sense of what you can borrow. You can get an MIP for free from most lenders. They'll usually have an online tool. You'll just need to provide some basic information about yourself and your financials, and they'll give you a rough idea of what they might lend you.

Calculate your budget

Also remember that you need to consider all of the costs of buying a house, and make sure you can afford more than just the mortgage deposit. Factor in:

  • Survey costs
  • Legal fees (conveyancing)
  • Stamp duty (if applicable)
  • Moving costs
  • Immediate repairs or improvements

This preparation ensures you know exactly how much you can afford to offer and prevents you from making commitments you can't keep.
