What computer should I invest in?

[Ashton Karp]

It's time for me to buy a new computer but unfortunately I am not tech savvy. I am more than willing to learn but to get going I need advice for what brand or model I should be looking into based on my needs. My real estate future will include being an agent and running a buy and hold business with construction being a part of my model. That's a general idea but that's what I want. I want the ability to edit videos, make virtual tours, work with CRMs and that sort of thing. I only know what I know though so tips on what I may require from a computer is appreciated. A laptop may be preferred due to portability but if there are suggestions of desktops I will look into them. 

Thank you, BP.
