Furnishings cast slotted for the property." - If you get creative on this maybe it's enough to the make the numbers work. 

We moved it to a 1 night minimum because we were having trouble filling weekend slots, which was rare for our listing.

Can I risk building a home at the slot and sell it which will be faster than selling a lot? 

It's only been a week, but what are my options if they do not return and the RV just sits in the slot? 

Please provide a fewtime slots for next week so we can coordinate sending someone to checkboth apartments at a time when the tenants are available.To help me better understand and to better identify the source of theleak, please provide a picture of your bathroom showing where the leakis located, such as above the toilet, bathtub, or another area.we’ve noticed that you’ve asked in almost every email, both now and inthe past to let you know when your ceiling will be repaired.

In this case, he gave us ample notice to (most likely) fill that slot, however, I'd like to protect us in the future.

Parking slots, shared parking?

But one can buy a pearl every now and again I suppose kind of like playing the slots looking for that 100k payout :)

(We switched to commercial financing when we ran out of loan slots with Fannie Mae.)  

Most seem to want a showing (i am currently making a quick google sheet with available time slots on a Sat morning for my dad to show).
