I keep comparing to Aussie and other countries world wide.Buyers agents pretty much don't exist and only listing agents do.true, US is almost always the most complicated one, in other country no need to have buyer agent but there're more, no need to pay tax when selling house, no need to put all 2000 pages disclosure when selling house  , no need to have house with so many certification (required in some states ) before renting it out , no need to hire expensive licensed american-born General contractor when repair house, no need to call specialized licensed educated electrician / plumbing with ipod because it's just .... plumbing. no need to pay tax with annual increase .... no need to pay ridicilous amount of insurance every year no need to check their credit score and immigration status when renter is impying LOL the list is on and on

Locating, marketing and negotiating the deal, understanding the underwriting, using escrow and title, and all of the basics are used so that it prepares for the more complicated techniques.

It's about to get a lot more complicated and I suspect they couldn't answer any specific questions right now as everything is in flux.

It depends on how deep is your knowledge, your experience, your willingness to invest in automation technology, always having a backup or two, your location in the community around you, of your property is in pristine or run down shape, whether you use the cheapest appliances or make things complicated or not,You didn't mention whether self-managed whether you mean you are on location or remote.

This gets complicated and is not a DIY project.And, depending on the specifics, various other limitations can come into play.

its not that complicated.

Why over complicate this? 

This is very complicated.

Further, if there is Structural work being done that can complicate which companies will quote.  

It's a super powerful platform but can be very complicated.
