<prompt> Human: Lets say I live in a house with roommates. They each pay me their share of the rent each month via cash or check. I then write one check to the landlord.Lets say a full months rent is 2000. Each month I will always receive it, and I always have to pay it. So this is cash that comes and goes with a zero sum, but still passes through my hands.How can I take advantage of this extra temporary cashflow? Some ideas that I had:Talk to landlord about paying via credit card, and use the roommate cash to churn credit card rewards airline pointsOpen an online checking account with some sort of rewards to churn rewardsFront 1 month rent out of my own pocket, then put roommates rent into some sort of interest-gaining account. Pay rent out of account but instantly replace with next months rent to maintain 2000 balanceAnyone have any experience with this? Or is it not worth the trouble?  <response>: Front 1 month rent out of my own pocket, then put roommates rent into some sort of interest-gaining account.wat
