You shold always get one, it's only a few hundred dollars and for that you get another pair of eyes that are looking for issues.

For some, I think pairing up with an investor is wise.

Do you own marketing or try to find a wholesaler to pair up with.  

From this post and others I've read I feel like my best option would be to pair up with a Realtor at least while I learn the ropes since I'm starting small.

Ex: John was really well-spoken, Susie constantly interrupted me, Steve clearly had no idea WTF he’s talking about, etc.By calling 10 accountants, you’re “pairing them up” against each other, cross-referencing their information and getting smarter (and more confident) with each call.At the end of all your calls, you’ll be mentally tired, yes, but you just learned a ton! 

It was for a pair of Duplexes ,class D area . ( LOL ,Check us out trying to come out the gate in a blazing fire)The COMPS are $74 , Asking was $105K for one and $99K for the other. 

Have feasibility done by Integra. doing lots of legwork and talking to lots of people in the industry to pair up with the right ones now.

However, I'm pairing them up to the targets on my list.  

Just think about them on an individual basis...or even as pairs, where when there is a problem with one, it leads to one of the other "targets" as the solution.  

Your income has to cover that, plus any maintenance to the machines, as well as your time to collect the money.For a single pair of machines, a speedqueen could cost $1000 per unit or $2000.
