Concernedly time purchase a home

[Truong Vu]

I would like a feedback on should I buy a home now or wait for opportunity. I am able to make 50% down payment but i wont have much financial available for at least 1 years emergency fund if something went wrong. I dont want to tap on my 401K because that is set for retirement, period!!!. I must have another vehicle due to my current vehicle is due to replace. I try to keep it up as long as I can so I can save more money for a new or decent used car. I dont know what happen in the future. I prefered two or three more years that I can work and save money to buy a house ( $300k) and car (30k) with cash. I am living with my parent and they dont hesitate but I am desire to move out cause I had family and son; and want some privatecy. In the area where I want to purchase; house is in the $400K for OK house, nice one is $500K in orlando Fl area. What should I need to do? Wait or looking for a house to move out now? I am really wandering for months and even years about this.
