Where to invest cap ex, repairs, vacancy reserves?

[Adam Bearup]

Hello BP community, I'm interested to learn what most investors do with the portion of rental income commonly set aside for cap ex, repair, and vacancy costs. Does it go straight to the bank? Invested in CD's or a money market account? It makes sense that this money be liquid to use at a moments notice, but it'd also be nice to get a return on this money, wouldn't it? Best regards, Adam Bearup
