This is not what you asked, however I am going to throw another thought in: If you can find mobile home parks or certain RV parks, you can likely get more accelerated bonus depreciation than with other types of assets, multifamily, self-storage, etc.

So it's not uncommon after a project that there's a couple hundred feet of 12/2 still left, and that will go into our storage facility for the next project.

Where does everyone go to find out if a storage  facility is feasible in the area?  

My partners and I recently purchased a small self storage facility outside of OKC.

Killed the weeds in the lawn, put down sod, rehabbed the nasty garage and shop to make them look appealing, added a finished attic storage area to the garage, painted kitchen cabinets, installed new AC and all new plumbing.

I get the gist of the idea and don't necessarily disagree with it, only that everyone and their brother these days thinks their time is worth $200 an hour.No joke: at one of our rentals there's a storage shed.

You need a organized system to save and record your income / expenses.I save receipts to my google drive(Any online storage will work such as dropbox or apple drive)I record all my transactions within google sheets(excel will also work)I then make my accounting work easier within quickbooks(Xero, Stessa or quicken will work here)

I have a RV park, vacant land, and a self storage tactility right now with the RV park insurance renewal coming up.

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.

Like fold towels for storage a certain way.
