This can often be broken down in different ways. Does a unit that typically has a 7-night minimum stay need a boost in business? Consider moving the minimum to 3 or 4 nights during slow periods. Take a look at your competitors. Is your pricing competitive in the marketplace?
Another area we routinely see as being a big hurdle in converting customers is turn days. Are your customers limited to checking in and checking out on Saturdays, and only staying in increments of 7 nights? That may have worked well in the past, but travelers are putting an extra premium on flexibility in 2018 and beyond. Do you really want to exclude the majority of your potential guests, who would prefer to check in on a different day? The marketplace is changing, and guests want flexibility with check in/out days and length of stay. Keep that in mind as you are making changes, or pitching the value of being more flexible to your property owners.
