How do I choose tenants if there are multiple, very good pre-screened candidates?

[Muki Naseer]

I have at least 4 couples who (at least in pre-screening) score almost identically high. I have not yet asked them to apply, and therefore I haven't collected any application fee from them. I don't want ALL of them to unneccessarily pay the application fee and have their background/credit run if i'm only going to pick 1. Should I go with the background check on the first couple and do the due diligence on the references etc. and then move on to the next, and so on and so forth?

How do most of you handle this "good problem" ?
