I believe they are a much more secure and predictable investment.  

Nothing wrong with this approach but what you want is a measurable, predictable number of potential deals flowing your way so I wouldn't recommend relying solely on the passive deal search.You may have access to information to help you prospect for these deals on your own.

Think Indianapolis is a great market for investing - we just released a list of our top 5 markets for BRRRR Investing for 2025 (just an analysis and prediction) and we put Indy at the Number 1 spot

It can also be hard to predict how your own personal strategy may change over time.

With the population in Texas predicted to double by the year 2050, it is a good place to invest. 

Have you been more or less successful than you predicted?

The property is in a solid area where Neighborhood Scout puts it at the highest rating for appreciation, predicting 40% appreciation over the next 3 years, and we'd look to refi or do a HELOC in 3-5 years to realize that gain, and I'd probably buy them out with my portion at that time.

Market Appreciation is the least predictable, but historically, where you will make the most money.We still use the BRRRR strategy in Jacksonville, FL.

So, the length is not really predictable...but there are unique options that will give you more control over this, like Cantor Fitzgerald has some 721's , and then there is a secondary market that Inland Capital has..I think it is them.. 

I predict interest rates come down, and perhaps housing prices in certain areas but not in most areas.
