Start by thinking about your situation. Make sure that you know exactly what situation you are in before making any decisions. For example, be sure that you are ready for the financial responsibility of owning a home, be sure that you have found a home that is big enough for you in the present and in the future, and be sure that the home that you have chosen is in the area of town that you want to settle down in. All of these variables can make your experience a negative one if you are not completely sure, so sit down and carefully consider each of these before making a final decision.
Buying is almost always better than renting! The only advantage of renting a home is that you are not responsible for the maintenance costs of the property. Other than that, it is always better to own because it gives to the opportunity to build equity and provides you with tax breaks. It also protects you against any rent increases that your landlord may try to force on you and you can paint or alter the house in any way, without having you answer to anyone.
Owning your home is an investment, while renting one is the equivalent of paying into someone else's investment. Since you are more worried about your own future than your landlord's, it makes sense to buy as soon as possible. The real estate market will always be around, which makes this a relatively low risk investment as well. While this investment does bring about responsibilities, they are not overwhelming for anyone to handle and they are offset by the freedom and you will enjoy while owning your own home.
By using an experienced real estate agent, you leverage their confidence and experience. The more experienced your real estate agent is, the better the chance that he or she can get you through any difficulties that may arise while buying a home. These difficulties can arise if you try to buy a home for less than market value because this can drive the market as a whole down. Seasoned agents, however, will have dealt with this in the past and will likely be able to get out through anything with little problem.
