Is the rate or tax different if its not your primary residence?

I currently have a VA loan with the primary lender being Wells Fargo.

The complaints of note investors trying to purchase or invest in notes via crowdfunding platforms is that by the time they see the listing, the investment has been fully subscribed.  

I just wanted to use this platform to introduce myself and get to know some of the BP community! 

I'm new to the RE investment , and new to the biggerpockets website at the Same time .I need some help guys to understand how it is possible to use the HELOC several times.I've got a relatively good grasp on how to use it the first time , based on the equity of your primary residence. 

If you're a realtor, there are some slightly better platforms for managing listings like Placester.

I’m getting ready to temporarily move back into my rental property, while searching for a new primary residence in the coming months.

We've also paid our primary residence down so we could get a HELOC for future investments.

The mortgage is still in my primary name and he as the secondary. 

My primary concern is that we are not handing large sums of cash to someone who, despite great referrals, runs abroad with our money.
