You can do some sourcing yourself through Facebook groups, and online RE communities , and even pick up the phone and cold call some homeowners that may be tired landlords, don't owe anything, and have built up some equity.With enough volume, you should come across some solid deals.  

You can find templates for joint venture agreements on BiggerPockets or other real estate investment websites.Next, consider joining local real estate meetups or online groups where you can network with other investors.

Run online marketing for a small business...everyone needs help with this. 

Quote from @Emma Johnson: Yes I checked It is listed as an option on their website everything online looks legit.

Becca,   glad to help.How did this guy find you in the first place or was there something on line that you saw and responded to..

You might be able to find a lot of this info online, on YouTube, here, etc and piece it together however as a busy professional I didn't have the time personally to try and fail - nothing wrong about choosing that path however I knew I didn't have time and I was in peace with hiring a coach to help me through my first deal, 8k is affordable in comparison with the 30,40,50k programs out there.

You are only really assessing based on CAP rate which tells me you are only looking online and assuming their CAPs are correct.

No reviews- can't find anything about it online. 

Or you can order online.

This probably sounds a little like wholesaling or being a Realtor, and it is.If you don't want to spend $1,000's to build this out and take on the associated tasks, there are other, more cost effective, options.I'd recommend looking for potential deals via free (or low-cost sources) i.e. local meetups/networking, Courts (probate & lis pendens lists), Realtors, Wholesalers, properties for sale online (especially those with 90+ days on market), etc.All the best!
