Lazy investment portfolio - I would appreciate your feedback

Profile: Married without children, age 30, works in high-tech, free savings of about ~5.5-6k USD per month, living in Israel.

Investment time: 5-7 years, there is a chance that we will want to buy another apartment after this time, for that we may have to sell some.

Stategy: Lazy, passive, index funds, diversity, not "stock picking", "Buying the haystack not the needle".

Starting point:

• Real-estate: A house worth ~400K USD. I own 30%, and mortage of 70% (It is a common mortage in my country). The rent pays for the monthly mortage payments.
• Salary provisions: A monthly provision of approximately ~ 2K USD for a pension in the s & p track, and ~900 USD for a study fund in the equity track.
• Security fund: ~60k USD, do not intend to touch this money.

Blend:

I focus on the iShares stocks, it is easier to buy in my country.

Option 1: 

• S & P - 30%, iShares Core S&P 500 UCITS ETF
• MSCI Europe - 20%, iShares Core MSCI Europe UCITS ETF
• MSCI EM - 10%, iShares Core MSCI EM IMI UCITS ETF
• MSCI ACWI - 20%, iShares MSCI ACWI UCITS ETF
• MSCI World Small Cap - 20%, iShares MSCI World Small Cap UCITS ETF

Option 2 - remove ACWI, add to S & P and europe: 

• S & P - 40%, iShares Core S&P 500 UCITS ETF
• MSCI Europe - 30%, iShares Core MSCI Europe UCITS ETF
• MSCI EM - 10%, iShares Core MSCI EM IMI UCITS ETF
• MSCI World Small Cap - 20%, iShares MSCI World Small Cap UCITS ETF

Considerations:

• S & P "only" 30% because I invest ~2900 USD from my salary to pension and study fund mostly in S & P and the USA
• Geographic diversity: USA, Europe, Emerging markets. I understand it covers the most
• Do not pick specific countries / sectors - optimizing diversity
• I give 20% to small cap. Is it too much? would you choose a different weight? Would you involve medium cap as well?

What would you change?

Thank you :)
