These guys are not players they are market makers.  

again nothing to stop the sound waves (my lease required 50% coverage by area rugs, I do not enforce that unless we get complaints).If is quite possible you are chasing ghosts here, you can spend a lot of money sound insulating the place, and decrease all the sound frequencies above 125Hz, but not effect any sound at 50Hz and then your next tenant is a bass player and everyone complains.You can get a professional sound meter from amazon for less than $20, those do not have frequency ranges, but they will let you know if the person who is complaining is crazy or not, and you can use that meter (that is calibrated) to compare against your local noise ordinance to see if there really is a problem.

Most times, the bigger players can be too busy to take on leads and opportunities even by doing simple things like answering the phone and/or returning phone messages.

This renaissance proves that investor demand for mortgage securities remains high, reflecting renewed confidence that stricter underwriting standards will make conduit lending an even stronger channel than in the past.Although the GSEs remain significant players in multi-family lending, regulators will continue to debate what their role should be in mortgage finance going forward.

I think  this is a decent list, but honestly there are some players to stay away from, especially if you are doing rehab and need trades, construction people, or project management in Indianapolis. 

So I noticed these podcasts on the media player and I started looking well I came across Dave Ramsey.

At this time flipping will be even more time sensitive than normal and new players to the game will suffer.

What other players should I include in this process? 

Really looking for a team player, as I am serious about purchasing multiple properties / asset types, and working with one person/team for the long-term. 

Those cash buyers do NOT buy via real estate agents, because real estate brokers don't have the distressed properties for sale in the MLS, because these properties are being found, "brokered", purchased, and rehabbed completely outside of the world the RE agents/brokers live in.And perhaps my biggest point is this:  The big players that are licensing our WeBuyHouses.com brand are almost all broker/agents AND investors, and those guys wholesale deals to cash buyers.
