Systems and softwares will be your best friend.
Definitely purchase a PMS, Guesty for hosts and Hostaway are well reviewed. This will handle all of your guest communications and make sure that your calendars are synced across airbnb, vrbo and booking.com
-Splurge on the interior design, often times the interior design is a major differentiation between like properties. If it isn't your strong suit find a friend or family member who can help you out there.
-Spend on the professional photos, all of the work/money you are investing is going into 20-30 photos, hire someone who has shot Airbnbs before if possible stage the property in a way that makes them emotionally connected to the property. Think smores by the fire place/ floaties in the pool/burgers on the grill etc.
- Pricelabs for dynamic pricing is an incredible tool to help you manage your pricing. You can get pretty granular here with things like orphan day pricing, adjusting minimums as it gets closer to the actual date and creating seasonal pricing too.
-I'd also purchase Airdna for your market for the month. It is 10 or 12 dollars and it will show you all of the top performing properties in the area. Look and see which ones are performing the best and try to incorporate as many of those elements as possible into your property.
There are a few other things, but if you do all of these you will set yourself up for success.
