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

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. 

Hi Daniel,I think what I have been seeing for the most part is that duplexes up to four plexes are not necessarily marketed at certain cap rates but whatever the market and comparable properties have been selling for.Maybe a factor that contributes to this is that anyone with a traditional home mortgage can purchase up to a 4 unit building without getting a commercial loan.

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

Like a traditional refinance into a 30 year at a lower rate?  

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. 

Please any advice would help $50k can get you $200k worth of real estate using traditional financing.

Only that you must establish your intent to hold for investment.But nothing prevents you from later converting a property held for investment into your primary residence.
