Buy these ASX ETFs in July for passive income

There are a growing number of exchange-traded funds (ETFs) to choose from on the Australian share market.

This means that whether you are a growth investor or an income-focused investor, there is likely to be an ETF out there for you.

With that in mind, let's now take a look at three ASX ETFs that could be top options for income investors in July. They are as follows:

BetaShares S&P 500 Yield Maximiser (ASX: UMAX)

The BetaShares S&P 500 Yield Maximiser could be an ASX ETF to buy for passive income.

This fund has been created to give investors access to the top 500 companies listed on Wall Street. This includes many of the largest companies in the world such as Apple, Exxon Mobil, Johnson & Johnson, and Walmart.

And while the S&P 500 index itself only has a very modest average dividend yield, this ETF's actively managed covered call strategy means it has been able to pay out significantly more.

For example, its units currently trade with a trailing 4.7% distribution yield.

Vanguard Australian Shares High Yield ETF (ASX: VHY)

A more traditional option for income investors to look at is the Vanguard Australian Shares High Yield ETF.

This popular ETF gathers together a group of ASX dividend shares that brokers are forecasting to provide big dividend yields. Importantly, it does this with diversity in mind and doesn't just load up on banks and miners. Vanguard limits how much it invests in any particular industry or company.

Among its ~70 holdings are dividend payers such as BHP Group Ltd (ASX: BHP), Coles Group Ltd (ASX: COL), Commonwealth Bank of Australia (ASX: CBA), Transurban Group (ASX: TCL), and Wesfarmers Ltd (ASX: WES).

The Vanguard Australian Shares High Yield ETF currently trades with a dividend yield of 4.9%.

Vanguard Australian Shares Index ETF (ASX: VAS)

A third ASX ETF that could be a good source of passive income is the Vanguard Australian Shares Index ETF.

This ETF has been designed to track the local ASX 300 index. This means that you will be owning a slice of Australia's leading 300 listed companies.

And while not all these companies are dividend payers, there are plenty in the fund that are. Among this diverse group of shares are companies such as Lovisa Holdings Ltd (ASX: LOV), Macquarie Group Ltd (ASX: MQG), and Woodside Energy Group Ltd (ASX: WDS).

At present, this ETF trades with an attractive dividend yield of 3.7%.
