Hi Joselyn,
1) You can compare the current PE with the historical average PE of the company. Personally, what I use is that if the company is a quality one I am willing to pay PE between 10-15x depending on the growth. Higher growth I am willing to pay 15x. Most of the time I will not pay more than 15x unless the company is those medical company or brands like Starbucks, Macdonald.
2) To keep it simple, use PB for property companies only.
3) Only use EV/EBITDA when the company have higher depreciation. If the company depreciation is not high than PE is more applicable
