Business owners looking for storage or car fanatic looking to securely store their "toys"How did you find this deal and how did you negotiate it?

Infrared toy shows cold spots - but not where the air might be coming from.

@Joe Villeneuve Block Buster, Toys R Us, Sears, Kmart, and Borders all were corporate guarantees with solid credit at one point in time.

I've been toying with the idea of scrapping the building and starting fresh, creating a six-story building with at least six units, one per floor to rent out.

I have also toyed with the idea of building true generational wealth and ruling from the grave where I scale to a larger amount of houses in a family trust and pass the income to my heirs in perpetuity. 

@William Kuczmera - I have been toying with this idea myself.

I come from a data science background, so I'm accustomed to creating models to derive the incremental ROI of each variable.I hear some people saying "get the $10,000 hot tub", and I get that, especially if it's a "table stake" that your property needs just to be considered by guests.However, when thinking about less standard amenities, like putting greens, gaming rooms, billiard tables, pool toys, etc. what tools or methods do y'all use to evaluate if a given idea will deliver a positive ROI?

I have not built anything more than duplexes, but are toying with the idea of my first fourplex.  

Plumber goes out and says its stuffed with wipes, tampons, plastic bottles, condoms, toys.... you get the idea.
