The main reason to borrow money to buy a home is this: If you try to save while renting, you still have to pay the rent every month. If you borrow money to buy the house, then you're not paying rent, but all the money is going toward the house.
I have no idea what price range you're in but just suppose for the sake of discussion you have $1,000 a month available for housing. You could rent for $800 per month and save the remaining $200 toward buying a house. Or you could get a mortgage for $1,000 per month and put all $1,000 toward this house. If you save while renting, all the money that you put toward rent is money that COULD have gone toward buying a house.
The main reason NOT to borrow money is to avoid paying the interest. When you get a mortgage, you typically pay a LOT of interest over the life of the loan. Depending on the length of the loan and interest rates, it routinely ends up that 50% to 75% of what you pay goes toward interest.
Which decision is better for you depends on many factors. I couldn't begin to give you advice without a lot more information.
Other things to consider:
When you buy a house, you are responsible for maintenance. If the roof needs to be replaced or the furnace breaks down, you have to pay to fix it. When you are renting, the landlord is responsible for maintenance and your rent covers all these expenses. People often say, "Oh look, I'm paying $1,000 a month for rent and I could buy an equivalent house with a mortgage of only $800 per month. Buying is a much better deal." Not necessarily, because the $1,000 rent includes maintenance but the $800 does not.
How likely are you to want to move in the next few years? If you rent and you decide to move, you just move out and stop paying rent. Worst case, you may have to pay for a few months remaining on a lease. If you own a house and you decide to move, you have to sell the house. Depending on market conditions at the time, that may be easy or it may be hard. It may be impossible to get back what you paid for it, or even to get what you still owe on the mortgage. You'll have to pay a realtor to help you sell the house, which in the US is typically 6 or 7% of the sale price. In the worst case you might find it impossible to sell for months or even years, and you'll be stuck paying a mortgage on a house you're not living in.
