I would explain it’s the procedure:
- got through all the viewings
- register all the interests (this can be done over a day or even weeks depending on when you are satisfied with the level of interest) and includes info on perspective tenants.
- inform the chosen person, do background check and get the full deposit before you let everyone else know the place is no longer available. This can easily last 3 days.
i find aggressive perspective tenants are not a good fit in general.
it could also mean you are underselling…
Hope this helps.
