Even simple things like making sure each photo on Airbnb has Alt text and that is fits into their SEO categories, I was surprised that more people weren't aware of it. 

There are never full photos of the mechanicals and basement and roof line so you will never have even a bare inkling of what the potential repairs will be.

It's likely a scam anytime they sound like AI or the grammar is weird or they use the word "kindly", if they ask for you to respond to them off-platform, if they say their employer will pay for it, if they ask if the dates they've specified are still open (when they can clearly see they are open on your calendar), if they ask for a video of your property (they probably want to set up a duplicate listing with your photos and video and scam others out of money), or if they want a long term booking and they have just joined the platform and have no reviews (could have been evicted from somewhere else, and hope a newbie will let them in with no background check, they'll end up not paying or credit card is bad).  

Did have high quality photos/ great listing title and description?

HI, I wold defimitley update  the photos.

If so, this would be a huge unlock for someone wanting to split their property and build a second home.

However, if you're concerned about the cracks in the photos above, I think most would agree that they are normal settling cracks and that no further precautionary measurements need to be taken.

Focus on key areas first (like floors, walls, kitchen, or bathroom), which may help you handle the costs more gradually, even if it means moving in furniture or updating fixtures down the line.Also, since the tenant left it in rough shape, be sure to document all the damage (photos, receipts) in case you decide to pursue reimbursement through their security deposit or in court.

If selling is your priority, focusing on completing this one first could unlock the equity you need for the next steps.Your idea of forming an LLC is smart, especially if you’re considering investors.

Now the photo came thru!
