Building a portfolio that generates reliable passive income has become a priority for many investors, especially retirees and those seeking consistent cash flow. While income-focused opportunities have expanded over the years, traditional dividend-paying stocks no longer offer the yields they once did.
The S&P 500 (SPY) currently delivers a dividend yield of about 1%, well below its 30-year average and close to the low levels seen during the peak of the dot-com era in early 2000. Although that does not automatically point to another technology bubble, it does suggest that broad market valuations remain expensive from an income investor’s perspective.
As a result, many investors have shifted attention to three specialized investment structures: Real Estate Investment Trusts (REITs), Master Limited Partnerships (MLPs), and Business Development Companies (BDCs). Each offers a different way to generate income while benefiting from favorable tax structures.
What Are REITs, MLPs, and BDCs?
Although these three investment categories operate in different industries, they share an important feature. They generally function as pass-through entities, allowing them to avoid corporate income taxes by distributing most of their taxable income to investors through dividends or distributions.
REITs
REITs primarily invest in income-producing real estate. Their portfolios may include apartment communities, shopping centers, industrial warehouses, data centers, office buildings, healthcare facilities, and senior housing properties. Rental income collected from tenants supports the dividend payments made to investors.
MLPs
MLPs operate mainly in the energy infrastructure sector. Their assets commonly include natural gas and oil pipelines, storage terminals, petrochemical processing facilities, and port infrastructure.
One important consideration is taxation. Investors who own individual MLP units typically receive Schedule K-1 forms instead of standard tax documents, making tax filing more involved. MLPs also may generate unrelated business taxable income, making them less suitable for retirement accounts such as IRAs.
BDCs
BDCs serve a different role. These companies provide financing to private, middle-market businesses, primarily through short-term floating-rate loans. Some also take equity positions in the companies they finance. Because of this model, BDCs are often described as publicly traded private credit firms.
Software companies represent a meaningful portion of borrowers across the industry, although firms such as Main Street Capital (MAIN) maintain relatively limited exposure to that sector.
Despite operating in different industries, all three investment vehicles share a common objective. They seek to earn returns on assets that exceed their weighted average cost of capital, allowing them to generate steady cash flow for shareholder distributions.
Market Performance So Far This Year
Performance has varied noticeably across these three sectors.
Among the group, MLPs, represented by the Alerian MLP ETF (AMLP), have delivered the strongest price performance this year. REITs, tracked by the SPDR Real Estate ETF (XLRE) and Vanguard Real Estate ETF (VNQ), have also posted relatively stable results.
BDCs, however, have experienced the weakest performance. The VanEck BDC Income ETF (BIZD) has fallen by roughly 12% year to date, making it the biggest laggard among the three.
Several factors explain this decline. Interest rate cuts implemented by the Federal Reserve during 2025 reduced earnings growth for many BDCs because floating-rate loan income declined. Yet market sentiment appears to have played an even larger role.
Why Investors Have Turned Cautious on BDCs
Concerns surrounding artificial intelligence have created uncertainty in the private credit market. Many investors worry that AI could weaken the business models of software companies, reducing profitability and making it more difficult for borrowers to meet their financial obligations. Since software firms account for a notable share of loans across many BDC portfolios, these concerns have weighed heavily on share prices.
At present, however, those fears have not translated into widespread financial problems. Revenue growth, operating margins, and interest coverage ratios among many borrowers have remained relatively stable. The possibility of future disruption still exists, but current financial results have yet to confirm the market’s worst expectations.
This gap between investor sentiment and business fundamentals has created an interesting valuation picture.
Dividend Yields Tell a Different Story
Current dividend yields provide another perspective on these investment categories.
Both REITs and MLPs are trading with yields that remain close to their respective 10-year historical averages, suggesting their valuations have stayed relatively balanced.
BDCs stand apart. Their dividend yields now sit well above long-term averages, largely because share prices have fallen while dividend payouts have remained mostly unchanged. Higher yields often reflect greater perceived risk, yet they can also signal attractive value when business fundamentals remain intact.
Whether this discount proves justified will depend on how private credit performs over the coming years. For investors who believe current concerns have been overstated, BDCs may offer a more appealing combination of income potential and valuation than either REITs or MLPs.
How Economic Conditions Affect Each Investment
Economic trends influence REITs, MLPs, and BDCs in very different ways. Interest rates, inflation, economic growth, and recession risks all shape future performance.
REITs
REITs generally perform well during periods of moderate economic growth and falling interest rates. Lower borrowing costs support property values and reduce financing expenses, while stable occupancy and rental income provide an added layer of resilience.
During recessions, many REITs benefit from lease agreements that often extend from one year to several years, helping stabilize cash flow even when economic activity slows.
MLPs
MLPs tend to react differently to interest rates because their performance depends heavily on energy infrastructure demand. Commodity prices often have a greater influence than borrowing costs alone.
Many MLPs operate under long-term contracts that provide relatively predictable cash flow. Strong economic growth can create additional opportunities for new infrastructure projects, although contract structures often moderate earnings swings compared with more cyclical energy businesses.
BDCs
BDCs have one of the strongest relationships with interest rates. Since many loans carry floating interest rates, rising Federal Reserve rates typically increase loan income. Falling rates usually reduce earnings potential.
Economic growth can also support lending activity by creating more financing opportunities for private businesses. However, BDCs often face greater pressure during recessions because middle-market borrowers may experience more difficulty meeting debt obligations.
These characteristics make each investment category suitable for different market environments. Investors who expect interest rates, inflation, or economic growth to shift in specific directions often evaluate these sectors differently based on those expectations.
Which Investment Fits the Current Market?
The best choice depends largely on expectations for inflation, interest rates, and economic growth.
If inflation remains elevated and interest rates stay higher for longer, MLPs may continue to perform well because energy infrastructure businesses can benefit from strong demand and stable cash flows.
If inflation eases and interest rates gradually decline over the next few years, REITs could regain momentum as financing costs decrease and real estate valuations improve.
BDCs become more attractive for investors who believe concerns surrounding artificial intelligence have been overstated and expect economic conditions to remain relatively stable. Current valuations already reflect a significant amount of caution, creating opportunities if loan performance remains healthy.
On the other hand, investors expecting a recession, especially one driven by weakness in technology stocks, may prefer carefully selected, financially strong REITs due to their relatively defensive characteristics.
Examples of Companies Drawing Attention
Several companies illustrate how investors are identifying value across these sectors.
Among REITs, Rayonier (RYN) continues to attract attention because of its extensive timberland holdings. The company owns a large land portfolio that can gradually be sold or leased for more valuable uses. Shares also trade below the company’s estimated net asset value, allowing management to sell selected assets while repurchasing discounted shares.
Within the MLP sector, Energy Transfer (ET) offers a dividend yield close to 7% while distributing only a little more than 50% of its distributable cash flow. Its broad network of natural gas pipelines and midstream infrastructure could benefit as additional gas-fired power plants begin operating over the next several years.
Among BDCs, Morgan Stanley Direct Lending (MSDL) has received attention because most of its portfolio consists of first-lien, senior-secured loans, which are generally considered lower-risk investments within private credit. The company’s non-accrual rate remains relatively low, while its shares trade at roughly 80% of net asset value (NAV).
Around 20% of MSDL’s loan portfolio is tied to software companies, an area that has raised concerns among investors. However, the company limits risk by keeping individual loan positions relatively small and maintaining disciplined underwriting standards. The discounted valuation has pushed its covered dividend yield to approximately 11.7%, making it one of the higher-yielding opportunities in the sector.
Why Diversification Still Matters
No single income investment performs well under every economic scenario. REITs, MLPs, and BDCs each respond differently to changes in interest rates, inflation, and business activity, making diversification an important strategy for reducing portfolio risk.
Current market conditions have made BDCs particularly interesting because investor sentiment has weakened more than underlying business performance. Even so, REITs and MLPs continue to offer valuable income opportunities depending on an investor’s economic outlook and risk tolerance.
Rather than relying entirely on one sector, many investors prefer holding a mix of these income-producing assets. A diversified approach can provide dependable cash flow while reducing exposure to any single part of the market, especially as economic conditions continue to evolve.
