@Adam ShaThe only person that can properly answer this question is someone that analyses markets on a national level or someone that invests in all 3 of these markets.The answers you're going to get from everyone on this forum that falls outside of the above is going to simply tell you their market is the best market. 

I am trying to decide if this is a worthwhile endeavor.From what I have read, the main benefit is early access to MLS for purchasing homes and saving on commission costs while selling homes.This leads to two questions: - Is simply having early access to new listings worth $600, or is it only worthwhile if I plan on flipping and selling a property on my own?

I have hate for no one.This is simply an observation or something that is important to understand when you are in this business- because when you go to turn certain units you may run into this big extra cost.

The best cities I've done it in are actually the more expensive one's because there's more willing of a seller to let me buy deep(as they're likely owning the house mortgage free) and every fix I do makes more than a 1x on it simply cause of the neighborhood.

I would simply establish relationships with realtors and your investors. 

In her second post, Jen mentioned that simply keeping the two already occupied units would cover the mortgage.

Sounds like your bank simply wants your personal guarantee with your name on the loan and not that of your LLC.

This way in the event that something happens to me anyone can simply pick up the binders and run the portfolio.

But first try simply reminding them. 

don is just making excuses ...hes never done it and cant even speak of it -- a birds eye viewput simply - you have to do it -- all the other jibber-jabber on here just reads as complaining and excuses -  it is real estate to a degree.
