I have over $200k equity in my primary and I will be taking out a HELOC to fund my first deal but looking ahead - I'm not sure how long we're going to hold on to this house so I'd like to focus on building a business line of credit that I can always depend on. 

I'd be very wary of this setup.

Well then from what I have seen in the past the majority of these investors end up losing their money as they have no idea what the rules are, I can only imagine how they are handling your money - and it appears this entire post is a case study for what I am saying.

I'd love to!

I'd appreciate any recommendations.

In regards to learning more about real estate and maybe how to answer those questions I'd recommend listening to BiggerPockets (Rookie and Real Estate Podcast), there are also some market specific real estate podcast you can check out depending on the area you want to invest in. 

i personally use my regular phone but you could use a google voice number or an actual physical work phone with a different line. i'd do google voice so you're not carrying around 2 phones. :)

Hey @Seallington Touch I'd recommend attending some local meet ups and listening to the podcasts.

Thank you,Matt MortgageNewsDaily.com is a very good resource for daily tracking of conventional rates and they also have good content explaining the reasoning behind the moves (MBS, treasuries, etc.)DSCR Loans a little harder as its going to be a range and based more on deal specifics, I'd check youtube, etc - also would generally track the 5-year treasury yield and add about 3% to get a general daily ballpark

I'd go with a flat to keep things simple.
