So I think you have a great advantage being in central Austin.
As a HO, I’ve learned to take a critical eye at your listing and how you present your offering. For me, my home is not small but it’s certainly not fancy, ocean-front, upscale or any of the things that get listings a billion applicants in a day. But, that doesn’t mean I don’t have other strengths that I can emphasize in my listing. Take a look at the 5 sub-categories that THS ‘grades’ HO on: Communication, Hospitality, Cleanliness, Pet Behavior, and Accuracy of Listing.
To me, if I have just an average home, then I need to be above average in other categories. So I level up on hospitality (offer use of my car, welcome dinners, flex days on the front and back end of a sit), Cleanliness (deep clean before every sit, or hire a cleaner), Communication (always cordial, concise, and professional - but not cold - and also includes having a clear welcome guide available timely - sitters should not have to chase you for this), Pet Behavior (be realistic - and if your pet has some needs, think about having some help available for sitters to be able to get out and about one or two days a week - a drop in sitter, doggie daycare, etc - just some help to make it a good exchange), and lastly Accuracy of Listing (be upfront about any issues with your sit - eg I have a hairy dog and my home will never be fully free of dog hair, my pets wake up early, my cats like to sleep on your head - or you only have a couch for sitters to sleep on - whatever it is, just put it out there in the listing. Best to be transparent vs it coming out in an ugly review later!).
So if your place is small, that’s ok. Be upfront about that, and what sleeping arrangements you can offer sitters. Then down the rest of your listing highlighting how awesome Austin is, bragging about how well behaved and easy your pets are, and how you as a host want to be welcoming and accommodating for sitters who, in exchange, will care for your pets.
So, don’t worry if your home isn’t a fancy castle. There are so many aspects that can make a sit fantastic for all involved - focus on excelling at those - hospitality, communication, etc. That’s how you make THS work when you have just an average home - make it super clean, make it super welcoming, be clear in your listing, and be accommodating for sitters who want to take a day or so and look around.
I think you’ll definitely find great sitters if you embrace the spirit of the exchange! Good luck - it’s great when it works as intended!
