First Rental Property w/ Adjacent Vacant Lot Included, Options?

[Jarrod D Day]

Hello everyone!

I'm asking the community for help in turning an adjacent lot that came with the purchase of our very first property into a cash-flowing asset!  This our brand-spanking new foray into investing, and the property we had our offer accepted a couple of weeks ago.  We are finishing up the the due diligence  and are ready to close.  In the deal, the property comes with an adjacent vacant lot measuring 0.45 acres.  Not huge, but we need ideas on how to cash flow this area.  The property itself comes with a detached garage.  I am thinking of a storage unit here for the renters, but I'd like to know--for those investors that have built storage units before, what was the estimated cost?  How much did you charge per month?  Is that even a smart move on Single Family units, or should storage unit investments be reserved for Multifamily units because of a higher return?

We also considered mobile homes but I think it's too close to the property...

My wife and I appreciate any creative ideas from the community!
