They haven’t listed the place on their own website yet.

I'd stay away from any mechanical work requiring clients come to the location, could just bring so much trouble on you.  

There is a time during the meetings to bring up deals like this. 

You need to incentivize them to mentor you or partner with you, either you work pro bono for them or bring something to the table of value.To your comment about "shady" or dishonest, I would encourage to you be as honest and forthcoming as possible, I don't know about you but I got into real estate because I wanted to do something meaningful, profitable for my family's benefit, I wanted to benefit from my level of effort rather than giving it to someone else, and most of all I wanted to make the world a better place by improving whatever it is I am working on; I want to be able to lay my head on the pillow at night knowing I did everything I could today to move forward in a positive direction and did so with integrity in order to prevent any form of regret. 

I would only ever bring in a plumber/electrician if A) it was a large multi-family (a dozen or more units - which I haven't yet graduated to) or B) I knew there were potential major electrical/plumbing issues.

If so what evidence did you bring?

However, I've been using the Bigger Pockets website and resources for long enough to add a few tips for you!

@Kevin Solomon , look for a portfolio lender that will allow you to bring all your properties together into one loan.

Do not underestimate the risks that brings with it.
