Just to let you guys know, As a Buyer you don't have to pay anything to hire a REALTOR. REALTOR fees are paid by SELLER. If you are not working with a REALTOR as of yet, I can provide you my service and assist you to find a property you are looking for and share my personal home owner experience and professional inside knowledge with you.
From my own experience, I can say it is always a best bet to go with professional. Interview few REALTOR's and see for yourself which one can work with you as a team.
You want live in your home for long time. Don't make a MISTAKE of buying by yourself, Unless you have previous experience of taking crucial decision like this which require huge investment of life savings and you know what you are doing. Good Luck to you on your way to Become a Home Owner.
