Are there team members (RE agents, wholesalers, lenders, PMs, contractors, etc) you'd recommend?

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.

Wholesale?

Quote from @Andre Lemberg: I've been using  Smarter Contact for over two years as a real estate wholesaler.

There are plenty of deals in Philly on and off-market from wholesalers, who are pretty decent in Philly compared to other places.You will need to get your GC license here and learn the permitting process and necessity here as well.

I am working on a wholesale deal in the Morning Star area on Franklin Blvd and the seller is interested in a quick closing.

Your best bet is to find and contact all of the top local wholesalers and go to work for one of them and see what they do right and wrong and see if it's even a business you like.

I do SMS, cold call, mail, online, wholesalers, etc.

I see the HUDs and wholesalers are on a lot of our deals I fund.. 

One of my wholesale lenders used to be willing to finance these, I can't remember the CLTV requirement of the top.
