The best thing you'll get from some of the intros is a few useful materials that will whet your appetite for more information.Your money might be better spent if you can partner with a mentor or coach who can walk you through your first deals in exchange for a fee.

They think they are investing when really all they are doing is parking excess cash with the hope of appreciation since the actual return through rental income is miniscule. 

I think 70% is a bit excessive but that's beyond the point, so long story short yes it might be a problem or at least it has been in my experience :)

I'd bet by the time you pay that loan off you will not be able to get a loan at 4% anymore.If you are a prudent investor you should be able to earn more than 4% elsewhere (SP traditionally has returned 6%, and is the most passive investment you can make) and as RE investors we certainly seek returns in excess of this, so don't worry about paying down that mortgage so quickly.

That seems excessive.  

Do I want to pull all the excess cash out?  

So, by buying it for less than market value, you might be causing yourself excess capital gains taxes later on.

@Cole Hagen my feedback would be: 1) don't commit income tax fraud by purposefully under-reporting your income, I may be wrong, but I'm pretty sure the IRS rule is that other/misc. income in excess of $600 must be reported, and 2) if you ignore 1) and do chose to not report it, it's probably not a great idea to post about the fact that you're considering doing so on a site where you have your full name posted, how easy would it be for a Google search to turn that info up or for someone to report you to the IRS based on this post?

She also was subletting my house out so there’s was a lot of excessive damage.

It depends on your appetite and financially where you are in your RE career.
