Financing through credit unions

[Corey Bogaski]

For my first property I used a broker who has access to over 20+ lines of financing. 
someone told me to go through a credit union, specifically Clearview. 
I was going to set up an account there (keep my RE investments separate from personal banking) but another person told me Clearview was a bad option to go through. 
This is a 2 part question; what is the best experience yinz have had with credit unions and what would be a good recommendation for me to open up another account for my RE investment (1 property so far so mortgage/utilities and savings for said property). 
thank you !
