6-plex rental property financing

[Seyed Hamidreza Mohammadi]

I was wondering what is the best money borrowing option (private lender, bank, etc) for the following situation and what interest rate would I get?
- A 6-plex apartment complex with a ~500k price
- For rental purposes, I would not occupy
- This is my first home-buying ever ( I rent myself)

- My credit is Excellent (750+) and salary is 100k+ range (household 200k+)
- I can put in 10-15% down

Thanks for the help.
