Applying for expat retirement visa

Hello, and sorry to re-ask what I'm sure has been asked many times before, but I need the most current info so I can leave as soon as my house sells. (And whether on this forum or the internet in general, info really seems to vary.)

Because of the US political situation, I am moving to Ecuador permanently ASAP. I know I should have started with the paperwork a LONG time ago, but I really did not want to believe what happened would happen.

So, a few questions: IS the retirement amount required TODAY $1,275/month? And if it's just a little over that, will it be accepted? (I will have some money from the sale of my house before I leave as well as my social security.)

I THINK I found all the paperwork needed, but can I do this myself or is it better to have help? If so, can anyone recommend anyone/any company? I sent a query to one site, but got no answer back.

Will I need to visit a consulate in the US if I do it myself or can I start the process, come over on a three-month visit and finish it in Ecuador?

That's just a start, but if I can get those questions answered by one or two of you, I would really appreciate it.

Thank you. Karen
