Information for buying a house

Hello,

I want to know how easy it is to buy a house. I dont know much about mortgages and different types of taxes to be filed after getting a mortgage/house. Those who have gone through the process of buying a house can give some guidelines. What should I look into before buying a house. Lets say if I decide which house I need to buy. Do i need to see any documents from previous owner ? Do i need to involve a housing company ? Does buying a house change my tax filling ? How to know about property taxes ? Do i need to tell government that I have bought a house so that they can send me some tax documents . I would really appreciate if someone can give me step by step process of buying a house
