These postions are advertised on Craigslist all the time and are typically part-time.

Probably the toughest in the U.S. from our perspective (we are actively advertising/investing in that area for the past year).  

I advertised on postlets.com.

How do I advertise my real estate deals in biggerpockets. 

If the whole point of due diligence is to make sure everything is in order from what was advertised and offer an opportunity to re-state terms or back out legally from a deal, then it would seem those contractors that did all the engineering/appraisal/inspection work would still need to get paid somehow -- which would then come out of investors pockets on that deal that did not close.

I was reaching out to the GCs who advertised their services in the hope of connecting with someone who might be able to service my needs.    

While it may seem counterintuitive to advertise the open house to homeowners who already live in the area, there are two reasons why I do this: Local residents could have family or friends who are looking for a home, and they can help me spread the word.People will see how dedicated I am to selling homes in the neighborhood and be more inclined to work with me if and when they move.

Also why are the advertised syndication returns so much higher than DSTs?

I've rented/listed my MTR via both third-party booking sites (they screen) and self advertisement (I screen).For tenants that do not book through a site, my vetting process is no different from what I do for LTRs; application, background check, etc. and the tenant pays for the screening.

So it may not be the best way to determine if he is doing a good job of advertising the vacancies.Since you are happy with him managing your other properties, why not help him out some, suggest Graiglist, telling him the success you have had in the past.
