Vacation property down payment pros and cons

[Steve Bell]

Looking at a STR to make first real estate deal on. Can anyone tell me why a lender might discourage 10% down on a vacation rental? I understand it's possible that interest rates would be higher than putting down 20%, but would there be any disadvantages of putting only 10% down on a vacation rental other than interest rate? Especially if I am trying to minimize out of pocket funds to begin investing. Thanks for any advice.
