The sooner that you can have crews actively working on-site, the better.

I'm fairly new in the industry as well, and most of the sources I've checked at first require a subscription (CoStar, WSJ), but I found this newsletter called Zeroflux Real Estate who consolidate real estate news from such sites.

I see advertisement in Zillow, redfin etc. sites.

I do try and tweak pricing just so it sees that there is active updates on the listing sites.

However, on my back burner is a direct booking site and I'm leaning toward OwnerRez (once I get through Ski Season).

It makes it easier when you put things into sites like Air BnB and whatnot.

Make sure that your area states it directly.Otherwise, let the booking site handle things. 28 days isn't that long IMHO depending on the area or reason for traveling. 

With Airbnb prices rising, we loved the idea of investing in a few different small apartments scattered around the world so we would have a virtually free place to stay, and when we were not there we would make money off of sites like Booking and Airbnb.

Is it an official inspection or some notes on paper? 

Once again, love the site and community here thanks everyone!
