@Herman2 You said you might be accessing the garage and you'll be caring for the garden, so it seems you live close by?
Yes, entire house rentals can be party magnets, but they are worse when they have remote hosts. If the host lives in another dwelling on the property, or next door, or down the block, and that is clearly made known to guests in the listing information, and in messages to guests, that normally kiboshes the party crowd. So does meeting and greeting the guests rather than having self-check in. When there is a human interaction with the host, rather than a faceless, off-site host situation, guests tend to behave more respectfully.
And yes, lower maximum guest counts lead to fewer problems. Even if the guests aren't throwing a party, a listing for 10 is going to result in more wear and tear and possible damages, even if it's accidental, than a place that's set up for 4 or 6.
And of course the amount of cleaning and laundry and sheets and towels needed is much more intense with larger groups.
It also depends on the location of the listing, the type of guests you market towards, and who it attracts. A house that sleeps 10, with trendy decor, a pool and a hot tub in LA will be much more of a party magnet than a rustic cabin that sleeps 10 in the backwoods of Maine.
And hosts need to become adept at asking the right questions when guests ask to book, picking up on red flags in their messages or bookings (someone booking a 4 bedroom house for 8 guests, but only listing 2 guests on the booking would be highly suspicious, for instance).
It would be really helpful for you to peruse posts on this forum on a regular basis to get an idea of the various challenges and situations hosts have to deal with, how they handled it poorly or well, and the advice given by other hosts
