Step 2: Get a Mortgage Agreement in Principle
A mortgage agreement in principle (AIP) shows sellers you are financially prepared.
Benefits include:

Most estate agents in London will ask whether you already have an AIP before accepting an offer.

When searching for property, consider:
- Transport links

Popular London property types include:
- Flats
- Terraced houses

Step 4: Make an Offer on the Property
Once you find the right property, your estate agent submits your offer to the seller.
At this stage:
- The property is not yet legally yours
- The seller may accept higher offers
- Negotiations may continue
This is why acting quickly after your offer is accepted is important.
