Putting down less than 25% on rental property

[Soup Nikk]

Hello BP experts,

I am just getting started with my real estate investing and I wanted to know if lenders would allow putting down less than 20-25% down on a rental single family home, knowing the following

- The person has excellent credit (FICO > 780)

- No outstanding debt

- Has a good salary and a history of stable full-time job. 

If yes, how much down is possible and are we looking at same rates as a traditional 25% down? Also, is this method recommended?

I had read somewhere that smaller/local credit unions can be flexible on their lending terms if the buyer doesn't have enough cash reserves but they feel confident as a repaying client and don't associate a lot of risk.

Regards,
