I'm wondering what the general Mustache stance is on keeping large amounts of money in different funds. For example, I know most people recommend having an Emergency fund. We keep 5k. For us that's a good number, that's two months of expenses, it's nice and easy. We've never had to use it for emergencies, even going through unemployment because we have multiple sources of income. But we've used it as opportunity money before and quickly replenished it.
We do have a budget and we save every month for things we will eventually use like car maintenance, life insurance premiums, clothes,etc. Those never get too big. But what about the really large funds? Like home maintenance? That could get enormous! Where do I draw the line? I hate having money sitting around doing nothing. We've never really kept a huge home maintenance fund but most people suggest 1-2% of home value... that's too much. Or is it?
