3-5 years to cash out while making 10% or so in the interim is way faster than 8-10% mutual funds.
If you invest with the right people. Historically speaking, excluding the last decade, average annual appreciation of both rents, and real estate is only a couple of percentage points ahead of inflation. Unless you have a knack for picking undervalued areas or adding value consistently over the long term, it is not a given that over the long term you will beat 8-10% in the stock market with a generic strategy of buying and re-financing.
Over the last decade a guy who had no eye for value and thought “negative leverage” was Chinese could handily beat the stock market.
