no brainer.
Buy the property.
I did my CPL/IR when I was 35/36 and am now flying 757's for a living, and I did it with my own money, because I got on the property ladder when i was 25.
I did not give up my previous career until I had the airline job. I did all my training part time with my income still coming in, including the IR training.
If it were me I would buy the property. Get the PPL if you've got the money and enjoy private flying for a few years. Follow your dreams, yes, but not at the expense of the rest of your life!
