My understanding is that the appeal of owning real estate yourself is housing mortgages gives you: (1) the cheapest leverage available to retail investors and (2) a loan that can't be margin-called. In an upmarket, this leverage lets you juice your returns. Say you only have $200,000. Then by getting a mortgage of $800,000 you get ownership of a house worth $1M. This gives you the right to the cashflow from renting the house out and in an upmarket, the appreciation in the house price. If the house appreciates in value by 20% or $200,000, then with your $200,000 investment your return is 100%. Buying REITs in he form of an ETF doesn't offer you either the cheap leverage nor the margin call-proof loan.
Another difference is that REITs own many types of commercial real estate, ranging from office and apartment buildings to warehouses, hospitals, shopping centers, hotels and timberlands, but usually real estate retail investors own are for housing.
The tax treatment of directly owning real estate is also extremely favorable to landlords in the US, particularly mom-and-pop scale landlords. Many will have businesses which make an economic profit and many of that subset will positively cash-flow, but for tax purposes deemed depreciation will cause their business to operate at approximately break-even or at a loss (offsetting other income). Then, when they sell the property, they either get extremely favorable treatment on exchanging for other properties (to defer taxes until post-retirement), ability to exclude capital gains, or capital gains treatment on income which was effectively business income [0] (and would therefore ordinarily be taxed at a much higher rate).
[0] This might be a little weird to wrap your head around. Suppose I am a landlord and, over the years, depreciate a building by $200k. That is a "phantom" cost. On my balance sheet, it decreases my cost basis in the building and decreases my taxable profits from the rental business. When I sell the property, because I've shifted that rental income into depreciation, my cost basis has fallen, so my gain on sale rises by $200k, but that $200k is now taxed at 0~20% not plausibly 50%+ (top individual bracket + state taxes + self-employment taxes).
(I have somewhat better than casual understanding of this because my father worked in real estate all his life and other family run mom-and-pop real estate operations, but feel free to run past your friendly local tax advisors.)
You could buy a house worth $500,000 with 20% down and a 30 year note. As long as you pay the mortgage, it doesn't matter how much the market value of the property changes. A drop of 40% in real estate prices that lasts for five years is not necessarily a problem.
On the other hand, imagine you put $100,000 into a brokerage account and were able to get 2:1 leverage. You could then borrow $100,000 and buy $200,000 of stock.
However, if the market runs into a bad patch and that stock decreases in value to $120,000, your equity is now only ~16.7%. This is below the minimum margin requirement (25%) for your account. Your brokerage calls you up and says you need to put an additional $10,000 in your account - that's a margin call.
If you don't have the $10,000 then your brokerage will sell enough of your position to bring your account back within requirements; possibly at the bottom of the market.
Real estate: 5:1 leverage, no margin call
Margin account: 2:1 leverage, plus margin calls
You can get around this by purchasing leveraged funds/etc. Although that should never be considered functionally the same. That said, you could consider real-estate interest+taxes+upkeep similar to the inherent loss/overhead in leveraged funds.
Ah okay very interesting, so I guess it would be fairer to say the REIT would be used in the case you were a less a real estate savvy investor perse and more someone who was looking to diversify I guess what I would call a layman's portfolio such as me.
