This utility helps you make the decision of whether to rent or buy. It considers such factors as the costs of owning and then selling a home as well as tracking the appreciation of the home. It then compares this to the money that would be spent paying rent. This tool then tracks the net value of the investment in a home during the time you want to spend there and tells you whether the home is a good investment or not based on the time of occupancy. Of course, there are numerous other factors that should be taken into account before purchasing a home and this calculation cannot possibly take all of these into account. The final decision should be yours, weighing all of the factors.
