For example, not having on-site storage can cause a lot of logistical and financial issues.

The buyer would need to show solid financials also of course (good credit, experience operating rentals, proof of funds for down payment and adequate reserves to cover any unexpected cap ex).

While real estate investing aims to achieve financial freedom, this is only possible if you invest where rents outpace inflation and there is significant, sustained population growth.

Financially it's amazing, but there are a few things to keep a look out for.1. 

If you’re looking for an REI strategy state your financial objectives, resources and time frame and ask for suggestions.  

But I agree with @Stuart Udis - when making offers on occupied rental property, I always review the Financials including the RR & T12.

If you come across a property with tenants in-place, you might ask for a financial report if available.

And IMO that has been decades in the making.I saw a recent survey of 4000 Gen Z and they said thay would need to earn 270k to feel financially successful.

To scale, I’d focus on defining financial goals, targeting specific property types, diversifying, and building a solid network.

A frank, hopefully insightful, dive into real estate and financial markets.
