What kind of investor are you?

Before you decide how to invest that $100k, ask yourself these questions:

  • What is my investing goal? Is it to save for an upcoming expense, such as a car or a down payment for a house, or are you saving for retirement? This is important because a short-term goal will require a different approach to a long-term goal; 
  • What is my risk tolerance? Investing is inherently risky, and your risk tolerance will determine your asset allocation;
  • How much do I want to be involved? $100k is a substantial amount of money, and investing it can seem daunting. Therefore, you might want to take a more hands-off approach and consider getting help from a financial advisor. 

Ultimately, your age, risk tolerance, investment time horizon, and financial goals all factor into your investment style. And understanding who you are as an investor can help you adjust your method as you age and your financial goals change.

1. Buying individual stocks

Investment type: Long-term growth

Risk Level: Varies

Broker to consider: Regulated, secure platform eToro.

Disciplined investing in the stock market over decades is generally the best way to build long-term wealth. And though returns can fluctuate from year to year, if investors reinvest their profits, they may even see compounding gains, which only grow more handsome as time passes.

For example, the S&P 500 brought a 26.89% return in 2021 amid the post-pandemic recovery. And even though the benchmark was down a whopping -19.44% in 2022, it’s still averaging 10.21% since its inception in 1957.

So, once you know what industry, sector, or company you want to invest in, you can shop for an investing platform. For the hands-on types, this typically means a brokerage account, such as eToro or Interactive Brokers. However, for those who require more assistance, opening an account through a robo-advisor is a suitable option. Alternatively, hiring a financial planner or investment advisor for stock recommendations might be a wise choice, particularly when a lot of capital is at stake.

Pros and cons of investing in the stock market:



  • High returns: Investing in the stock market can potentially generate higher returns than more conservative asset classes such as bonds;
  • Liquidity: Stocks are highly liquid, meaning you can easily buy and sell them at any time;
  • Low barrier of entry: Most retail brokers offer commission-free trading and no account minimums, so you can start investing with as little as $10; 
  • Build long-term wealth: Generally, stocks yield a generous annualized return over the long term. For example, as of March 7, 2023, the 10-year annualized return for the S&P 500 was 12.9%. So at the minimum, you’ll be able to stay ahead of inflation. 


  • Returns are not guaranteed: While stocks can outperform many financial assets over long periods, they may not do well over your chosen investing period; 
  • No short-term gains: Generating profits through stocks generally takes decades, not weeks or months;
  • Volatility: Share prices rise and fall minute to minute, taking the investor on an emotional rollercoaster. The best is, therefore, to check your investment only periodically;
  • Time: When buying individual stocks, you must manage your portfolio yourself. That means regularly following various company health indicators as well as overall market conditions and adapting the asset allocation in your portfolio as necessary. Unfortunately, doing all of that can take a lot of work.

2. Index investing

Passive investing is a long-term investment strategy for building wealth in which investors buy and hold a diversified portfolio of assets with minimal active trading in the market. 

Index investing is the most common form of passive investing. In this buy-and-hold strategy, investors purchase exchange-traded funds (ETFs) or mutual funds that track major market benchmarks, such as the S&P 500 or the Dow Jones Industrial Average and hold it over a long time horizon. The objective is to reproduce the financial index performance overall, to match, not beat, the market. 

The three most broadly tracked indexes in the United States are:

Pros and cons of investing in index funds and ETFs:



  • Low costs: The lack of frequent trading means transaction costs (commissions, etc.) are low with a passive strategy. In addition, while management fees charged by funds are unavoidable, most ETFs fees range from as little as 0.05% to about 1%;
  • Less risk: Indexing, by its very nature, offers greater diversification, minimizing portfolio risk;
  • Tax efficiency: The buy-and-hold method doesn’t generally result in a massive capital gains tax for the year;
  • Convenience: Owning an index is far less complicated to manage than a portfolio of individual stocks that require constant research and adjustment;
  • Simplicity: Taking a hands-off investment approach can eliminate many of the biases and uncertainties that can arise when you pick stocks individually. 


  • Volatility: Index funds follow their benchmark index regardless of the state of the markets, meaning if the market conditions are poor, the index funds will also follow the indexes downward. In this case, a good active manager may be able to limit the downside by hedging the portfolio or moving positions to cash;
  • Slow gains: Buying and holding can be a winning tactic in the long haul, but evening out the risks also flattens out the rewards;
  • Many index funds are formed on a market capitalization basis: For example, the S&P 500 gives higher weights to companies with more market capitalization. So, if, say, behemoths such as Inc. (NASDAQ: AMZN) and Meta Platforms Inc. (NASDAQ: META) experienced a weak quarter, it would have a significant impact on the entire index.

3. Real estate

In this section: How to invest $100k in real estate and rental properties, REITs?

Investment type: Long-term growth

Risk Level: Medium

In addition to stock market exposure, you might also want to invest in real estate. Here are five methods for adding real estate exposure to your portfolio:

1. Real estate investment trusts (REITs)

REITs are companies that own, operate, or finance income-generating real estate. REITs (as well as REIT mutual funds and REIT ETFs) are publicly traded and can be bought or sold via a brokerage account, making them the most liquid real estate investment available. 

Pros and cons of investing in REITs:


  • Pay dividends;
  • Highly liquid;
  • Diversified;
  • Takes the manual work out of owning real estate.


  • Dividends are taxed as regular income;
  • Hypersensitive to interest rates.

2. Crowdfunding real estate investing platforms

This method entails pooling money from several investors to fund a real estate project or investment.

Pros and cons of crowdfunding real estate investing platforms:


  • Possibility of investing in specific single projects or a portfolio of projects.


  • Require you to commit for longer periods;
  • Management costs.

3. Residential home

Buying your own home (typically by taking out a mortgage) is the most common way most Americans invest in real estate. However, while investing in your home can help you build wealth over the long haul, after property taxes, maintenance costs, and insurance, average annual returns are far less juicy than expected. 

Pros and cons of buying your own home:


  • Possibility of appreciation; 
  • Building home equity; 
  • Tax deductions and deductible expenses;
  • Government support for mortgage buyers.


  • Various costs like maintenance and repairs, insurance, property taxes, and the home loan interest;
  • Illiquidity;
  • High upfront costs;
  • Potential depreciation.

4. Rental properties

Rentals can offer steady cash flow and the possibility of appreciation over time. However, they are one of the most labor-intensive approaches to real estate investing.

Pros and cons of investing in rental properties:


  • Income-generating;
  • Properties typically appreciate;
  • Many expenses are tax-deductible.


  • Managing tenants and ongoing maintenance costs;
  • Vacant properties will result in losses.

5. Flipping properties

Flipping involves purchasing a property not to use but with the intention of selling it for a profit. However, like rental properties, flipping takes lots of work, including renovation work as well as learning to identify up-and-coming neighborhoods that will allow you to sell at a premium.

Pros and cons of flipping properties:


  • Ties up capital for a shorter period;
  • Can offer quick returns.


  • Requires substantial experience in real estate valuation, marketing, and renovation;
  • High out-of-pocket costs.

How to invest $100k for retirement?

If you just aren’t quite sure yet how and where to invest, here are a few of the safest ways to park your money:

  • Savings accounts: These are interest-bearing deposit accounts offered by most banks and credit unions. While savings accounts typically pay a modest interest rate, their safety and liquidity make them an excellent option for holding cash you want available for potential short-term needs. In addition, the money in a savings account is insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per bank;
  • High-yield savings accounts: Though the interest rates on high-yield savings accounts can be up to 25 times greater than with traditional savings accounts, they often require a minimum balance, and access to the account is limited;
  • Certificate of deposits (CDs): A certificate of deposit is an FDIC-insured fixed-term savings product. Unlike in savings accounts, the deposited funds must remain intact for the entirety of their term or risk penalty fees or lost interest. The trade-off for this reduced liquidity is higher interest; also, longer periods generally have higher rates. Investors with balances of $100k or more can even opt for a jumbo CD in return for higher interest rates;
  • Annuities: An annuity is a financial product offered through insurance companies that provide a fixed stream of payments to an individual, typically in the form of monthly income in retirement. The payout amount for immediate annuities depends on market conditions and interest rates. Because invested funds are illiquid as well as subject to withdrawal penalties, they are not recommended for younger individuals or those with liquidity needs;
  • Treasury Bonds, Bills, and Notes: Treasuries are debt instruments in which investors lend the U.S. government the purchase amount of the bond. In return, investors are paid interest or a rate of return. Then, when the bond matures, investors are paid the face value of the bond. Treasuries have different maturity dates and can pay interest in different ways. However, all have zero default risk since they are guaranteed by the full faith and credit of the United States government. Remember, treasury yields can fluctuate depending on the market and economic conditions;
  • Money market funds: Money market funds are mutual funds that invest in highly liquid, near-term instruments, such as cash, cash equivalent securities, and high-credit-rating short-term debt instruments. They should be used as a temporary placement of funds before investing elsewhere and are unsuitable as long-term investments;
  • Money market deposit accounts (MMDAs): MMDAs offer higher interest rates than traditional savings accounts, as well as check-writing and debit card privileges. These financial vehicles are FDIC-insured and provide a safe place to store your money, though they are generally more helpful in the short term than as a long-term investment. 

How to safely invest $100k — things to consider 

While you may be eager to begin investing your $100k, it’s essential to assess your financial standing as a whole and ensure the following factors are satisfied first:

  • High-interest debt is paid off: Ensure you have repaid any high-interest debt before investing. That includes credit card debt and debt from other loans, such as payday loans. For instance, the average credit card interest rate in 2022 was 19.42%, significantly higher than the average annual stock market return. Low-interest debts such as mortgages or auto loans, on the other hand, do not need to be repaid before you start investing;
  • You have an emergency fund: Establish an emergency fund in case of unexpected expenses, such as medical bills, car repairs, or job loss, before you start investing. A good rule of thumb for most people is to put aside six months of living expenses on a deposit account where there’s no risk of losing principal, like a savings or money market account. Importantly, having that cash available will also mitigate the need to withdraw money from your portfolio, use high-interest credit cards, or take out loans;
  • Space out your investments: Instead of investing all of your money once, try utilizing a dollar-cost averaging (DCA) strategy, in which the total amount to be invested is divided into periodic purchases of a target asset over a period of time. Spreading out your investment this way can lower the overall impact of price volatility and decrease the average cost per share; 
  • Don’t put all your eggs in one basket: To spread your risk and protect yourself from large losses, allocate investments across various financial instruments, industries, and other categories. In addition, a diversified asset allocation is essential because it has a massive impact on whether you will meet your financial goal. For example, if you don’t add adequate risk to your portfolio, your investments may not earn a significant enough return to meet your goal; 
  • Stay wary of fraud: Scams are getting increasingly sophisticated. Fraudsters are often particularly articulate and charming as well as financially knowledgeable, with credible websites, testimonials, and documents that are difficult to distinguish from the real deal. But as always, if it sounds too good to be true, it probably is. That’s why researching and understanding an investment is so important before you give someone your money. Start by looking for the company’s financial statements on the Securities and Exchange Commission’s (SEC’s) EDGAR filing system. Check out the Financial Conduct Authority (FCA) list of warning signs here, as well as the SEC’s list of questions to ask about your investments here


As you decide how to invest your $100k, focus on building wealth for the long term. Fortunately, with such a substantial amount of cash at the ready, plenty of options are available, from the stock market to real estate.

However, before you invest, take care of the basics, such as paying off debt, setting up or continuing to fund a retirement plan, and building an emergency fund.

Finally, consider your risk appetite and financial goals and create a solid financial plan before making investment decisions. Chances are, if you invest your $100,000 properly, it won’t be long until you’re researching how to invest $1 million.
