I should have added that I'm a guy. Typically thats the attitude you can expect in the OC dating scenehaha
It somewhat makes sense to me though; you've got teenagers driving down Jamboree in Lamborghinis, why would a girl be interested in a 25yr old guy living at home haha. My friends that still live with their parents have had the same experience...
Literally everyone I knew in my 20s rented an apartment. As long as you're not doing something dumb like renting a $4k amenity building unit, you should be fine.
Honestly, I went on a shitton of dates while still living in a jr 1bd apt in Irvine and driving a Honda Accord just fine. I definitely was making less money than you. Right before I met my future wife, I was online dating like crazy, like 6+ dates/wk.
I think you gotta ignore all this conspicuous consumption.
If you are really fixated on buying a home, you should consider a smaller property in the area (e.g. Keller Dr in Tustin Ranch) or moving to a lower cost area.
