Would it be worth putting money in my “safe” money in a Money Market ETF?

I am interested in using the interest/dividends from the MM ETF to pay my rent ($1,500/m). In my bank, I'm sitting on 40k liquid capital. It's not gaining any real interest. Would it be wise to move 30k to a MM ETF and keep a minimum of 10k as a reserve in my bank, which would cover 4-5 months of rent + minor expenses?

The ETF I am eyeing is the Vanguard VMFXX ETF. Which on average yields %5.04 compounding interest.
