A good resource for information is Consumer Direct.
Here is an overview of how the process works:
- Find out what your buying power is by finding out how much you will be able to spend on a house. This can be done by going to a bank. They will discuss the mortage options available to you. This maybe 3 times your income.
- .Find a house. An estate agent can help you this. You might have to visit a few estate agents as they only show the houses listed with them unlike in the States.
- Agree on a price.
- Get a mortgage.
- Move in.
Another resource about buying a house is the Housing office.
