I am getting close to affording that kind of downpayment (though my realtor tells me we can get in the market on a much lower percent down), and I'm still hesitating on buying. I dislike the inability to customize the place we live in but also dislike the theoretical lack of mobility and the actual necessity of having to do housework.
