I would agree with the prevailing sentiment. You can go ahead and interview 3 realtors and they would all probably tell you it is a great time to buy and blah blah blah… When you tell them you would be draining your savings and what would happen if you bought and lost your job I would be curious as to how they would respond.
I would consider trying to build up a strong nest egg before I did anything. You are only throwing away money on rent because you look at it that way. You feel tied to your rental because you refuse to consider a longer commute. Yet if you buy you will have a longer commute.
