Building your own shed is usually cheaper than buying an already built shed.
However you have to factor in your time and usually the shed can be built faster by a shed builder than someone who has never built a shed before.
Most sheds can be bought and delivered to your house or property for only $100.00 down and the first payment or sometimes not even the first payment.
I have a small portable shed that I bought and will have paid off in about 6 more months.
I only had to pay them $85.00 and they delivered it to my house and set it up.
In total the shed is gonna cost me $1,800.00
I could've built it for a few hundred dollars less but the good thing is that it was already built and all I had to do was move my stuff into it.
It's cheaper than renting a public storage unit and I will own the shed.
