Yes, you need to ask yourself a lot of questions about noise levels, rooming size for a cage (the bigger the cage, the better, even for small birds), time you can spend with the parrot, as they're very social animals and they need time with their owners each day, mess you can handle (parrots are pretty messy), $$ for toys, food, cage, vet bills, etc. . . Will the bird only be yours, or with a family (some birds bond better with families than others). Do you have young children? Are you planning on having children one day? Do you cook a lot, if so, throw out that teflon cookware. Do you have the patience to accept a parrot even if it bites, or isn't hand tame? Will you be around for at least the next 30 years to be with this creature. Some parrots can live as long as humans or longer.
I find that "talking" is the least important attribute to me and it should be for most parrot owners, but unfortunately, it's placed too high in priority on people's lists. If a parrot talks or not, does not make necessarily make it a good pet IMO.
Some small birds are also deceptively noisy. I had an umbrella cockatoo for ten years, one of the noisiest parrots on the planet, and I when I hear what other people consider "screaming" birds, I laugh, but some people are a lot more sensitive to noise than others. If you want a "quiet" bird, then forget about a parrot altogether. Although some may be quieter than others, birds vocalize and one needs to accept this.
Good luck on your quest for the perfect parrot. I spent months researching a new parrot, and in the end, I ended up with a hand fed, very tame cockatiel, which I feel is perfect for our family.
