Cameron, no apologies necessary. No offense was taken, whatsoever. I'm at the end of my career and won't be buying much of anything for my shop. I think I understand what you are trying to do. It's the reason people hate painting. Most folks have little patience and far too little experience, probably for the same reason. They look at a hallway with seven door casings, seven doors and a mess of base just for starters. And they try to do this in one coat. And, if you're not used to it, it's painful and slow. Spraying sounds like it would be the easiest, most effective way to paint. But, not always. For the home's exterior, an HVLP isn't the way to do it. It's not made for heavy, pigmented latex paints. That is when you need the airless. But, you'll need the proper spray tip for the paint you are using. You may need stilts, walk boards, paddle, brush, bucket, on and on. You also need to know how to properly operate your airless. It's not an easy project. But, if you take the job at hand in steps and complete each one in sequence, you'll have this project under control and the finished product will be much better. Concede that you will have to sand, prime, and use two finish coats. One guy, many hours of intense labor. I hate to see people seduced into buying equipment they really don't need, or won't be using after the project it is completed. There are few instances that spray painting are necessary for the interior of the house. If you have an airless, it should be perfect for painting the siding of your house. Just have everything you need set up before you begin. The first being the best paint from a paint store. Don't cheat yourself, buy the top of the line paint. I'm on your side, believe me.
