I have sent them a "Notice of Default" with 14 days to correct.

They should postpone it for 30 days.2. are any of you open to closing a deal like this (happy to share all details and make a connection) Does not sound like there is enough money in the deal. 

My wife and I are more than willing to change our address, license, etc and sleep in that house to satisfy this as we want to be truthful.So, does “majority” of the year mean 6 months and 1 day?

Since it is the same address you will designate 1 unit A and the the other unit B.

For a first deal it felt safer than a single family rental due to the fact that while possible, the chances of all units being vacant at the same time is much less than a single family being vacant.

For the last two years, I applied to a heloc at the same bank and was basically laughed out the door.  

Hopefully the questions are worded correctly, I have just been thinking about this over the past few days and figured someone might have some insight.

In our same $400k LA example the payment on a cash out DSCR would be nearer $2500+/- (interest only) for the first 10 years and then amortized over twenty years with a payment of $3280ish.

Does Tampa and surrounding areas have the same rules?

It can help take them out of the bidding war zone and they get a better home for the same monthly payment.
