Important questions prior to first investment property

[Samuel Qandah]

I am a current home owner of a personal lived in condo, which is the extent of my real estate reach. 

I want to get into real estate investing, but have several important key questions:

1) Should I start a LLC/ S-Corp and put all investment properties it that? Any starting advice on which route to take and some beginner/ fundamental info on this topic?

2) Can I put less than 20% (3%, 4..5..6..7%, ect.) down for an investment property that I do not plan to live in? How about ways in which I'm not using much of my own cash, HELOC?

3) Is it possible to acquire a property and get it to a point of occupancy fully remote or at least almost fully remote (I'm aware this would require in the least networking with local agents, finding a good PM company)?

Any and all knowledge and experience anyone can share would be extremely helpful and appreciated!
