Your friend bought and sold a condo in the same year or so? Maybe I'm interpreting this wrong. Cause the transaction costs alone are about 10% on a home sale, so it's not something you want to treat like switching apartments every year when they jack up the rent 10%, even if the general rental market doesn't call for such an increase (they know most people won't want to deal with moving, deposits, etc).
