What

What type of home are you after. Start with the basics:

How many bedrooms do you have to have?
How many bathrooms do you HAVE to have and How many do you want?
What level of quality are you looking for?
Will you improve the quality of the property to meet your needs?
Do you need Garage for storage or for a car?

Is a carport sufficient?
Just off street parking?

Are you looking for specific features?

Victorian?
Edwardian?
Californian Bungalow?

Are these types of properties available within your search area?

These are just some of the questions that will get answered throughout the search process. Very few people would be able to answer all of these questions at the first meeting.
