Just when is a good time to buy a home? Do you feel you've achieved steady employment? Have you maintained a decent credit history? Do you really desire to own a home? Do you want more space to have to keep clean? How about yard work? Be prepared to have at least a small lawn to maintain, unless you move into a condo where you don't have to maintain any yard or amenities, or move into the city where the only grass you see is a tiny bit creeping up from the cracks between the concrete, no wait, that's a weed! I'm getting off track here, sorry.
The point is, there are things to think about before buying a home other than whether you have enough down payment. Actually down payment isn't really an issue nowadays.
