would she be in profit today if she had bought at that time?

It doesn't matter if she profits or not. She wouldn't know at that moment of time. If she had proceeded, it was speculation. It is gambling.

My biggest concern is she's spending beyond her means. How on earth is she gonna pay back if the place cannot be rented for 2-3 months? Cry also no point. Every night sleep with toes shaking look at ceiling remember bank statement chasing for money already.

Please, invest responsibly.
