I'm not a facebook person but @Julie McCoy brought this point up earlier and I thought I'd ask the forum. 

Would it be worth it to put our website up and see what happens? Has anyone tried this? 

@Lucas Carl for both my LTR and STR, I never really had to buy advertising. There are enough free sites to fill my LTR quickly I never bother paying. Then for STR, I found a combo of some or all of the following Airbnb, Homeaway/ VRBO, Flipkey, Tripadvisor get me all the bookings I need. Right now, we were booked 3 out of 4 weekends in January, all of Feb & March, and have some bookings already for May, June & July.

I would be curious if others have used PPC and it generated additional bookings.

I used it for a couple of months, and I honestly didn't find it to be worth it.  I felt like I was spending for no reason.  Although, they don't really have a way to show who saw the ad and actually booked.  It's possible that I have several guests who saw my FB ad, but somehow they ended up booking through VRBO or AirBnB.  I just don't like the setup.  Maybe if they improve it in the future . . . .

I have a Facebook page for my STRs.  I get 2-4 inquiries per year from it.  None have panned out.  They just wanted to stay a night or two.  My minimum rental is 7 days.  My Craigslist ad gets 1-3 inquiries per week.  Most don't pan out, or the phone goes dead when the conversation goes like this..."How much do you charge per month?  I don't charge by the month, I charge by the week.  OK, how much do you charge by the week?  $400 to $1200, depending on the size of the house. <silence> <click>"

If I get passed this point and they are still on the phone, they usually rent from me because it costs less and has better amenities than a motel room.
