In no way am I suggesting the OP jump into this without evaluating the whole situation. If you look at it, I am the only person to recommmend meeting with a financial advisor to go over his entire finances to evaluate what he can afford.
Yes, I did state the rates are extremely low right now and later will most likely go up. So, I can see how you can see how I placed an emphasis on that, but that is not the only factor in this. The OP wants to purchase a home. The OP will have a job where he will be able to afford a house (how big should depend on what he and his financial advisor determine is an affordable amount to cover cost of mortgage, insurance, etc.). Now, If the OP finds out that he cannot afford at this point the type/size/location of a house that he wants, then at this time I feel renting would be in his best interest until his skills increase to a point where he is able to bring in a larger salary. But, if he can find a house that fits into his budget where he is very satisfied and meets his long term needs, then there is no reason to wait and no better time to buy - low interest rates and it is a buyers market.
By curiosity Yappy, have you ever owned a home? Are you married? Have you ever been in the situation where you could afford to rent or own? I am married. I own one house outright and have one other that I live in now. I've also rented. I know what it is like to give your money away to another home owner. It is satisfying knowing that even though you have this leash called a mortgage, in the end every check you give to the bank benefits you in the end.
If the OP can afford it now and this is his desire, then there is no reason why he should wait for a few years. If ytou read his posts, he will be in a stable position working for his father. He will have a steady income. He won't have to worry about running the business. His biggest worries regarding his career will most likely be getting his dental skills up to speed for a seasoned general dentist. I don't see any risks he would be taking by purchasing a house now. If you want to bring conservative into this, I think that buying now would be more conservative than waiting until later. Now, you know the prices are lower than they have been in recent years. The mortgage rates are at very low levels. For someone with a dependable income who is purchansing a home within their means, then now is the best time to buy because you know this is probably as good as it is going to get. If you wait, you run the risk interest rates will skyrocket and housing prices will go up again. Waiting leaves a lot of uncertainty in the market.
Overall, everyone now knows how I feel. I am basing my opinions on my personal experience of being a homeowner. I have not regretted it one bit, but then again I have always purchased my homes wihtin a budget I knew my wife and I could afford.
