What should I know about purchasing a secondary home?

[Huy Le]

I bought a primary residence 5 months ago, and put a lot of money into it. I would like to purchase an investment property, but I would need a 20-25% down payment - which I don't have. 

Can I buy it as a "secondary home" and put down something less than 20% and rent it out right away?

Are there other alternative methods I can utilize to acquire this investment property?

thank you in advance for you guidance!
