He says he will volunteer for any open slots if I don't cancel the lease. 

Tennyson Street/Berkeley is an awesome location in Denver, but those slot homes are pretty tiny, and you're right -- no storage, no parking.

Proof of how many slots were rented for what length of time.

If the potential partner can't be slotted into one of these 3 reasons to be a partner, then DON'T have them as a partner:1 - Do what you can't do2 - Do what you don't want to do3 - Do what you shouldn't do.

Just my quick 2 cents on this, I would say the following might be some: Flexibility of termsNo credit impact (don't use one of your Fannie/Freddy slots either)Ability to quickly negotiate and adjust if something comes up where you can't payI'm sure there are more, but those are just a few

Some of the habits I am implementing are setting aside certain time slots for tasks per day such as reading a book for 30 minutes, posting or networking on BP for 20 minutes, analyzing deals for 30 minutes, listening to a podcast for 30 minutes and analyzing stock for 20 minutes.

Just heard one guy got in pretty quickly and he just did the same strategy you did....just continually check the availability until he found a slot.
