Hi. Both of those life events are certainly worthy of a celebration. In 2017, I visited your chosen coastline while housesitting with THS.
You can certainly add that preferred sit information into your profile. For example, my profile currently states my chosen travel limitations based on the pandemic. However, there’s no way this will be brought to a homeowner’s attention, at least as far as I know.
What you can do instead is seek out homeowners and sits that fit your criteria. You can do a saved search on the website, narrowing it down to the coastline. You’ll then receive a daily email with new listings fitting that criteria. I’ll add a link here to a recent post reply I did. You’ll just need to apply the theory, as it was for a different area of the world but it covers
Searching for a specific area for sits.
Also, ‘favourite’ sits that meet your criteria. Take a look at @Petermac’s recent post on that.
I hope you’re successful in your search.
