Can they automatically re-new, if so, how do those projections work financially.5. 

You cannot close an RE purchase or sale without using an RE attorney.

STRs in non-traditional vacation markets like Stuttgart or Wiesbaden aren’t t just about breaking even they’re re about creating consistent cash flow that also serves as a long-term hedge against inflation.5.

Proximity to mass transit (mentioned by another poster re following them), proximity to downtown (maybe not so much now with work-from-home being a thing), proximity to airports, highways, pollution-belching industrial plants, hospitals, universities, the lake, etc., all help to define which South side neighborhoods have what it takes to overcome market inefficiencies and become "up and coming."

I just listed my last property for sale, a fourplex in Pocatello, because now I focus more on commercial RE and syndications to be a true passive investor and not deal with tenants and repairs.

-RE prof is a bit trickier. 

@Andreas Mathews admirable, but make sure you do some research so you understand what a PM can make.Starting your own PMC business will require 75-150 doors to make a decent living, depending on gross rents and your fee structre.Working for a SFR PMC as a PM, will require a RE license and you usually get paid a percentage of the gross rents the portfolio of owners/properties you manage generates.

Hey Jessie --what other passive RE models are you referring to?

A lot of investors provide comps (residential RE) but I avoid doing it because it's like telling them how to do there job.

I personally use the mass text capabilities through my Resident RE CRM.However I have a few friends who wholesale and invest and use Mobile Monkey to mass text and from what they say the price is pretty reasonable.
