I used our HELOC to get the property purchased. 

However, after doing some research on capital gains taxes  I may just keep the rental use my HELOC to purchase another rental.

I was able to get a HELOC on an investment property in Oregon. 

Thought of a HELOC on current townhome to cover investment property down payment costs, but not sure how that would be affected if we moved out of the townhome in a couple years.

My rental's that are in LLC's have had no impact on 1 refinance and 2 heloc's I have taken on my primary residence.

I also bought a fixer upper for my primary, but instead of flipping I'm working to get a HELOC instead because I love my neighbors.

I’d take a moment to work on mindset.  100k is a great amount of liquidity, if you can access all of it via a HELOC, great if not are you considering a sale?  

This house was supposed to be a flip and we opted to keep it and HELOC it after completion. 

Worst case scenario you purchase your first property using conventional financing and hard money/private money for the next, unless the first deal has enough equity to use a cash out refi or heloc.

Home Depot Card, HELOC, or a credit card), and then refinance into long term, lower cost debt (and pay off these debts) once the asset is stabilized. - The underlying goal of the BRRRR Method is to build a larger portfolio of real estate.
