have excellent credit and down payment 

I have been using residentresearch which is $32 and does an excellent job.

Their product is net leased portfolio DST.

A lot of forum members are very knowledgeable in their respective fields related to real estate investing, whether that is real estate sales, wholesaling, flipping, rentals, lending, self-directed IRA and Solo 401k investing, or tax and legal guidance.Discounts on some products and services are offered to BP members: https://www.biggerpockets.com/perks/proThe site has quite a few tools that can be helpful for new members.

As always, @Katie Noe of Commonwealth Homes Group - Keller Williams Louisville was excellent.

I’m an agent from Los Angeles that has sold going on 5 multi-units to LA investors for the purpose of both TV Production housing and AirBnb.Their cash flows are very healthy thus far, although this will depend on how you finance the acquisition.

But I started my journey with a realtor who's name I found here on BP, a PM I found on Roofstock (one of their "preferred" PM's), and an inspector I found online that had excellent reviews.

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?

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

@Nick Brubaker, this all depends on what loan product you are looking to get into.
