I would check out the selection of electronic pushbutton standalone door locks at the link below (no affiliation, just a site I've used) if you're still looking for a Yale 8800 series replacement. Many/most of these would probably fit the bill, at least in terms of functionality -- price tags vary quite a bit. But everything in this category is designed to work on a single 'standalone' door -- i.e. nothing that requires wiring or networking, and most combine a pushbutton keypad with a mechanical key bypass (so you could give a code out to renters, but keep the key for your own use). The catch would be that with one of these types of standalone keypads, you couldn't change the code without being physically present -- if that's a concern, you might want to consider a 'smart lock' like the "August" or "Remotelock." There are a number of these now if you search for 'smart locks with remotely changeable codes,' and some of them even interface with the Airbnb API to automatically grant access to people who rent your property. I don't have hands-on experience with those, but it could be worth shopping around and comparing reviews, depending on your specific needs.
