What Carl said is pretty good advice, a couple of things that might help you plan is know where you want to buy and find out how much homes in that area typically sell for now and what they are estimated to cost in 5 years. I'm in a similar situation, except I'm wanting to buy now and I've been looking for a home in my area and I'm find out that the price is way higher than what it was 5 years ago. Also research what home buying assistance program are available in your area to find out what they offer as well as requirements, especially if you are a first time buyer. Some lenders may have programs that only require 3% verses 20% down payment at closing. But, basically you just want to start putting money into a saving that you don't have easy access to, so you won't be tempted to spend and see if your employer has any programs that will match what you will put into a savings. Hope this helps and good luck on exceeding your goals!
