Here is where I would like to try to separate the house from the Frog/roommate area and ideally still have one Garage and a little storage space.

What kind of investment do you want single family homes, multi unit, commercial, trailer, storage etc.

I have the intention of building an 8 unit boat/rv storage building with an attached office; and later scaling up to more units.

Yes  get the basics as i have every receipt for anything ever purchased for this property from paint flooring. etc neatly sorted by year and month both physical and in cloud storage.

Indoor mailboxes, package lockers (Amazon hub), dog parks, pools, playgrounds, storage garages,etc.

Portion of land being subdivided will be used for potential development of Self Storage.  

Look into properties that have room to build another unit, a garage you rent as storage, maybe add a tiny home to the backyard or something.

B) Put the original washer and dryer that I have in storage back in and sell these two that my previous tenant left behind (with my permission)?

(There are several closets in the basement that can additionally be used for storage already)I am sure there are some liability issues and I would need to make all tenants sign a release of some sort.

I have 3 rental properties and a car storage for classic cars.
