Precast concrete is a low margin business overall but seeing as this is very special, it would be more that simple stock tanks and the like.I would go for in-ground all the way.

No paycheck can be a nightmare when the economy tanks.

In my case, I have residential rentals in one LLC, commercial properties in another, self storage in a third, and my real estate company operates in a fourth.

So we went into the commercial space and pivoted to self-storage.

Ample room inside and out for not only your vehicles but also for a workshop, storage, home gym, perfect for car enthusiasts, business owners or hobbyist.

If I want to get into self-storage, how do I find potential sellers? 

Their rent helps to tremendously offset my high rental expenses (apartment rent, building storage fee, parking).

Then, there are many other companies that sell every plumbing product for more-retail prices.A sewage ejector pump does not cost more than $300 to $450 at the very max and they take about 15 minutes to install after the tank is opened and the crap is removed.

So, most investors are turning toward small multifamily or other hands-off type commercial real estate properties.Aside from buying an entire storage facility or small multifamily complex on your own, another more affordable entry point into commercial real estate can be found through real estate investment funds.

Any recommendations on type  of tank or warranties?
