Typically the HELOC/Line of credit is set up as a fixed term interest only where you pay a minimum IO payment until it recasts/matures. 

do you have any experience with 3rd party websites that charge for identical information?

As of this October we are now parents of not 1, not 2, but 3 beautiful spontaneous identical triplet girls. 

I'm looking at a couple of NPNs right now that are balloon notes, 1 of which has a maturity date in 2017 and the other matured in 2015.  

If the house next door sold for $140,000 and is almost identical, this house should be valued at $140,000.

Int rate; pmnt amnt; date paid; & maturity are secondary.

That's like paying cash, but make sure you pay it off before the maturity date.

However, if you're buying notes correctly by 1)not having all your eggs in one basket; 2) have laddered maturity dates; 3) discounted the notes to give superior returns; and 4) monitor and enforce your notes properly, you'll do a lot better than someone who simply puts their money in a 2% CD.

When is the scheduled Maturity Date of the Note?

You won't get fantastic stores, sales hype about their information or strategies to be a wheeler dealer, you'll just find the facts and professional opinions.I understand people being lazy, especially younger investors starting out that want to be spoon fed their way to instant riches, that's naive in youth, foolish for mature investors familiar with the business world.
