Make sure you have GREAT broker relationships.

I know the relationships between a real estate investor, their team and mentor should be organically established, and honestly I would not have it any other way.  

What I wrote above does not create an attorney/client relationship between us.

Building relationships is powerful and can help you in a number of avenues, some outside of real estate.Granted, I can't speak for the other side.

We're actively seeking SFH buy-and-hold deals in Savannah (GA) and have need for an excellent PM company.Does anyone have a referral they can share?

If you already had a great relationship with an agent then you would likely use that agent but what if not?

Is it through an app, excel, or old fashion pen and paper? 

Say there is a syndicator raising $10M for an apartment complex.Say I personally have $100k to invest, but there are other friends/family of mine that want to invest, they just don't have the relationship or time to build a relationship/trust with syndicators.Am I allowed to "sub-syndicate" a group of my own network of investors to invest in the actual syndication? 

The most effective technique is to call the owner and start building a relationship.

If it were me, I'd much rather concentrate on fewer, but more impactful, relationships.
