In my area (near the beach) its mostly families and they want cabanas, baby items, chairs, coolers etc that we do not provide but I have a local vendor that delivers and picks up these items and charges a few dollars per day for each item, and give me a 20% referral. 

You said in your post  "If the notice was delivered by mail then the notice period begins when the Tenant actually receives the notice."

Almost an impossible way to “get started” as you’re going to need full purchase price in cash on hand or a HML willing to instantly fund you. 

However, some amenities consistently deliver high value because they attract more bookings, increase nightly rates, or result in better guest reviews.

More great news, our market just keeps on delivering. 

We specialize in short-term rental investments through our integrated real estate, mortgage, and property management services, delivering expertise at every stage of the process.

Honestly once the doc was signed, most of deal was on me to deliver. 

I believe that you don't get returns (failed to deliver) with bulk mailers so you don't know which addresses are bad.That's the simple stuff.My advice is to do various mailings that you or some prepares locally, that go out immediately, using 1st class postage.

It has surprised us delivering nearly $60k in gross revenue annually.

There is also a provision in the promissory note that states in the event of default, we must deliver the property back in the same or better condition from the time of purchase. 2: We will deed the property back to the seller & execute a contract for deed.
