True, I don't know you, but you've now given some information to work with. With a 300k income, you should be able to put away 50k a year without problem. That's a 20% downpayment after 3 years for a 750k house. (If you can't save 50k a year then that's because of lifestyle choices like what car you drive, when and how much you eat out and where you go on vacation. That's fine, but your choice, so don't complain.)

No. That's basically the definitions of those concepts. They are relative to how well off everybody else is.
