1. If I have an expired RUT, is there a process by which I am authorized to rent out (or let) my property in Santiago Centro without beginning a new residency application?
2. Is it unlawful for me to continue using my expired RUT for services that were already established while the RUT was valid? For example, I continue to use it for online activities like banking, paying my mortgage, property taxes, and even local delivery of groceries during COVID restrictions, etc.
The FULL story here:
I own an apartment in Santiago Centro which I purchased in 2018 with a mortgage while living in Chile as a legally authorized permanent resident. I left the country unexpectedly in Sep 2019 and I lost my residency status entirely by staying gone for more than a year (I know, I know, there are easy ways to extend, but I "dropped the ball" and have now officially lost it!). In december 2020, my cédula and residency card were confiscated at the airport "border" by PDI but I was granted entry as a "tourist". I am now awaiting a decision on my temporary visa application (based on ex-residency). I have had to get an extension of my tourist card to cover my waiting period.
During the last 2 years, a local friend had been renting the apartment from me with a notarized contract. Luckily I had zero issues because he was a trusted friend of mine prior to that; otherwise I would never rent directly because of the many nightmares I've heard. The apartment is now vacant and I had hopes of contracting a legal entity/property manager to handle leases/rents going forward.
I understand that my original RUT is now considered expired and INVALID because of this residency status loss. I continue to keep my mortgage, taxes, and community expenses paid through pre-registered online accounts (opened during my valid residency) and I make payments online using the same (now expired) RUT. But I cannot "negotiate business" with an expired RUT and I can't even withdraw a cashier's check (vale vista) from the bank without a valid cédula - I have 2 different bank affiliations in Chile and neither one will accept my foreign passport as a valid ID for in-person transactions. Likewise, the property Management company will not activate activate my contract until my credentials are valid again and I have a cédula to produce to sign the documents!!Waiting for my temp VISA was not originally going to be a problem because I would just wait for the approval and simply go get my new cédula - back to life as normal!
BUT, a few days ago, I learned that I must return to where I've been and leave Chile yet again. My VISA has not yet been granted or even officially stamped "en tramite" (in process). I only have their notice that a packet with my "mail code" had been received - the process status has not been provided/updated online for more than 4 weeks now. But even if it comes before I need to leave in a few weeks, I will likely lose that status as well since I will be unable to fulfill any physical presence requirements over the coming year.
I have researched this topic with Sii today and they offer foreigners an "investor RUT"... but then they immediately told me I would not qualify for it because those are not issued to people who were registered with a RUT in the past and they are given for purposes of paying taxes on "purchases" or "investment returns", NOT for paying taxes on "income" (which is what the rental payments to me will be considered). I have waited on the phone with extranjeria for hours without success....hence, the reason I reach out to everyone here...hoping for faster, but thorough, advice.
BTW - I have been an avid "reader" of the site for some years, but admittedly, I only registered officially today when I was unsuccessful to find a "clear" topic already posted on this subject. I have quite literally NEVER visited this site and been unsuccessful finding specific answers or help from related topics - this community is truly informed and its maintenance is completely on the point (nothing vulgar or rude lasts long and admin really adds value rather than detracting like most sites!!!)....Right on ALL CHILE, keep it up.

Many thanks in advance for your time and your support!
