You want someone who lives and breathes lending.

Deep breaths!

Here is what I would do:Take a deep breath and try to look at this from the 1000 mile view If you are worried about calling, send the tenant a careful polite and friendly text reminding them to sign the lease Let it be for a few days, then send another text and ask directly: is you plan to stay?

Just take a deep breath and be yourself.

That's known as having commission breath. 

Don't let them know you have access to money but see if you can find them a deal.Don't worry about how much money you make you're first deal or two because what you're learning is worth millions down the road and at 18 you've got a very long road ahead of you.just a little math with 350k if you had a HM/private lender give you 80% and covering rehab costs you could quickly be leveraging over 1.5 million dollars in real estate and turning that several times in a year (assuming your paying cash for properties with the proper margins) you could clear high 6 figures pretty easily (maybe more). but if you don't educate yourself you could lose 350k in a few short breaths. just my 2c.

#1:  take a deep breath

That hasn't happened yet so I'm not really holding my breath. 

Candor and frankness,  such a breath of fresh air.  

It’s either that or you’re tired all the time and then you realize 15 years later when you get your new furnace that you’ve wasted so much of your life being tired and unmotivated because you’d been breathing carbon monoxide.
