@Chris17565 I honestly think you'd do well to have a local co-host. Even if you set up the "perfect" system for you to be able to host remotely, what happens if something happens? Someone local needs to be around to handle issues that may arise. I think it *may* also help to keep guests on good behavior if they know that there's somebody local, and they've also seen a person- in person- associated with your property. For example, instead of having the security people show guests in, perhaps a co-host could do it. They could also check after your cleaning people, who may not be doing the *best* job, as your cleanliness rating has already taken a hit.
Now, about your cameras.....ultimately, they'll get you shut down. It's against AirBnB policy to have interior cameras. Even though you've "disclosed" them, the minute a guest complains, your listing will be suspended, and the guest will likely get a refund. By the way, disclosing them down in the section under "Safety and property" doesn't cut it. Guests don't read, period.
If you choose to keep the cameras, you need to put that out front and center in your listing description, but not even that will save you when the first guest complains. Seriously. And it will happen. You might be better off turning off instant book, and carefully screening your guests before accepting any reservations. That's likely a better deterrent for any badly behaved guests, than cameras.
Your price seems very, very low, but I don't know what the going rate is in Abuja, Nigeria, so that my just be my US economy-skewed brain. Anyway, good luck, whatever you decide to do.
By the way, I also use the TT lock app. I had purchased their "bridge" for Internet connectivity so I could program codes and see lock activity remotely, and the bridge was the biggest waste of time and money. It never worked properly, and messed up a lot of the lock function, so I eventually disconnected it and never looked back.
Cheers and good luck, Kia
