i originally just wanted 150k loan cash but they told me i should apply for 500k and pay off the other two loans for a better rate with themhttps://www.suntrust.com/loans/equity-line-of-credit

Weekly stays beyond 28 days and you now have yourself a regular tenant.Same applies if you initially agree to anything more than 28 days, like accepting payment for and agreeing to let them stay a month.

@Sean Beksinski thanks buddy, but no honestly there's many more experienced pros on here then me I just happen to be like a sponge with information and not scared to apply it.

Would they simply apply the roughly 1/3 Debt to Income ratio regardless of the heloc facility one has in reserve? 

I started the old-fashioned way, by making sure my credit/income was good and I applied for loans with banks and mortgage brokers. 

The "wiping the slate clean" will not apply.

My understanding is the 120 days only applies to Servicers of over 5000 loans correct?

Your personal umbrella almost certainly will no longer apply on these properties. 

I feel like I have built up a wealth of knowledge and am now ready to begin applying it.

And from most of the landlords I've spoken to, the multi share is great in markets that are super competative (like Seattle) but in smaller markets the fear is that they're making it too easy for an applicatant to apply all over the place without making any commitments.
