You think you're ready to buy your first house, but you're not sure if it's worth the investment? Our rent vs. buy calculator will tell you which option will result in lower monthly payments over a month, a year, seven years, and 15 years. Once you get your results, don't forget to think about other costs associated with renting and buying--like insurance, the cost of moving frequently if you rent, or home repairs if you buy. You should also remember to factor in other one-time fees for buying a home, like closing costs and realtor fees. Think you're ready to take the plunge?
