Seeking input on which tenant to choose (small office)

[Uwe K.]

Looking for some opinions on the following situation. I know there will be no right or wrong answer:

Small office building, and upper floor has three tenants. A + B with me for about 1 and 1.5 years respectively. Good tenants, mostly no complaints. Tenant C recently moved out. Now A + B are interested in jointly renting the C space for meeting, training, whatever. Alternatively I may have other new tenants to choose from. Which would you pick based on the following?

A (while also speaking for B, presumably), bugged me already before availability of the C space that they want to  use it. When it finally became available, he said they were still very much interested for mid October start, latest 11/1. Ok, all good, I didn't bother advertising since it sounded like a pretty clear decision.

Now (in a simplified version), they  are dragging their feet, have note rented, have not reviewed the lease draft from weeks go, and wasted some time that I could have advertised already. There is some indecision, possibly funds availability (or rather willingness to spend it) seems to be an issue from talking to A. We're talking small businesses and a rent amount of $750/month.

With that background, would you rent to them, or a new tenant? My thoughts:

- Con: They are indecisive, and while they now say they have the funds, I don't know how long it holds up. What if in 6 months they flip and decide they don't need it, don't want to afford it anymore? 

- Pro: They have been good and reliable tenants, I probably don't have to worry about much.

- Con: What if they part ways for whatever reason? One wants to move out and doesn't need the space? Will the other continue? The lease is written accordingly, of course (jointly and severally liable) . But as we know, that situation can always create headaches and can cost time and money.

- Con: With a third tenant, I can diversify the risk: If one tenant moves, only one third of the space is empty.

- Pro: The new tenant is still an unknown. Will they stay? will they pay? Will they create trouble?
