Should I offer to pay them for their consultation, or are these types of questions common as part of the PM vetting process and is a "courtesy service"?

You'll typically find that travel nurses want a 13 week term as that is the most common length of their contracts.

Now if you're pitching to the common landlord that is more dabbling in LTR and not business minded, that's a bit different.

And one more question I've worked with 3 REA thus far but so far none of them communicate timely (it usually take 2-3 days to get a response even when I'm letting them know I want to offer on a property) is this common?

Don't be dumb, use common sense for when to call. 7pm on a Friday is dumb, so is 6am on a Tuesday.

Same with anyone who gets 20 experienced-backed responses to their question yet ghosts the thread. non response or proper thank yous on PM's have caused me to not do those anymore I might write one sentence but it is weird how common courtesy does not resonate  with so many people on SM or maybe just on this site..

I've got the common sense items such as clean the lint trap, report leaks ect.

., what is common for your area?

They are not allowed in certain master planned communities.Summerlin, including Sun City Summerlin▪ Town Center▪ Skye Canyon▪ Cliff’s Edge▪ Symphony Park▪ Grand Canyon Village▪ Las Vegas Medical District▪ Providence SquareAnd these restrictions I find would be the most difficult for you to overcome - A short-term rental license does not provide authority to violate any common-interest community’s covenants,conditions and restrictions (CC&Rs).
