It has custom fields, unlimited storage for photos.

My business partner has a hypothesis that spending extra money to build an abundance of storage space into a rental unit will keep tenants "sticky".

Just plan to clean up and fix up for utility (and possible storage).

Someone I know owns a few storage facilities.

I also look for ways to bring in more income (such as coin-op washers/dryers), storage, etc. 

We started with these goals:Business partner wants to retire in ~6 years.I want to retire in ~20 years.We want to have $120k in cash flow by year 6 and $600k in cash flow by year 20.After buying and improving each business or property we want to outsource management.With these goals in mind we came up with a plan to invest $220k per year for the next 5 years ($1.1m total excluding capex), purchasing one passive income business (apartment building, storage units, ???)

@Nate Burgher the value add is the lot is large enough to add an airstream in back, add a storage locker since two of the units are super tiny, so they aren´t huge, just passable to maybe give me an extra 550-700/month which would almost give me free rent.

Thank you for the shout out Scott--hope all is well in the self-storage and development world!!

Let's pretend it's storage. 

I have an 8 unit apartment building that has two separate entrances (one for each 4 units) and each side has an internal door to the basement where there is laundry and extra storage.
