I'm also interested in self-storage and mobile home parks.  

Storage Parks2.

I’m posting today to ask if anyone could give me any information on getting into owning storage units.

I also started a portable self storage business which has been great for me. 

Sometimes a cat or dog is a chill well cared for and awesome addition to the house; other animals can pee everywhere, chew the door and window frames, bark all the time, go bananas and stuff their nose in the crotch of every visitor, or the owner simply will not spring for flea meds or vet visits, leading to problems all housemates can feel.Like many aspects of this, it's a balancing act, and something to be mindful of.While I'm thinking through it, other things to keep in mind include furniture, storage space, parking spaces, and visitors.

The good things are that all is resolved and I was able to convert the storage/garage room into the 4th room with city permit.

You said the lot is huge so maybe there's a way to use that extra land to make more money (add a unit, add storage sheds/parking spaces you can rent, create a garden/gazebo/outside work space that will enable you to raise rents, just spit balling here)...

Also, Boomers are notoriously fond of their "stuff", so self-storage facilities should continue to do well.Bolster your portfolio with those assets.

I have commercial residential rentals, storage facility, single family home rentals, and i and also buying houses and selling lease to own/lease purchase.

Next in line will be office buildings, followed by self storage, multifamily and industrial.
