One of the great rewards of life is finding just the right house to call home.  People tell me how happy they are that they found the house they wanted.  This does not happen without a lot of work and planning.  How you go about it and how much work you do is a choice you make.

Your choices are to go out and drive around looking for homes and do the whole process yourself and some people this every year. 

Your second choice involves less risk and less work where you can search the internet at all the real estate portals and look at neighborhoods and homes until you find the right house.  Then you could call the agent on the sign, who works for the seller of the property, to write the offer for you.  This may not be your best choice in terms of who represents you, the time involved, and did you see all the best choices.
