Where to keep your money while saving up for a long time?

[Tanner Shore]

Hey BP fam,

I am currently saving up to buy my first OOS deal and its taking a bit longer than I expected. I am able to save a couple thousand a month, but I am still a ways away. This made me start thinking that instead of just having that money sit in a high interest savings account, where else can I have my money grow while its waiting to be used to buy an investment property?

Possibly a dividend stock account, very conservative growth stocks, etc, etc. What do you guys do while you are saving up for a long time?

Thanks for any and all advice!
