Burning Bridges With Banks After Refinancing?

[Sean Salandy]

I am planning to purchase rental properties by using a HELOC on my primary for the down payment. The goal is to then refinance the new rental property after about 6 months then rinse and repeat. My question is, would the original bank that I used to purchase the rental property, frown upon the fact that I am refinancing after such a short period of time? Would this lead to them no longer wanting to approve a mortgage for me in the future?
