Sadly, it’s sat on the market too long and I’m looking to get creative with bringing the attention of many buyers looking for a good deal on a property (online auction or something else with tons of attention??)

Check out other online guides available here: https://www.biggerpockets.com/guides3.

Unfortunately, ESA (Emotional Support Animal) letters are tricky, especially with how easy they are to get online.

Is it customary that they have their process displayed online or in a pricing guide so I can shop around?

Build your knowledge base through books, podcasts, and online communities.

Is there any online services/tools where I can do the above DIY?

You can also check their reviews online at Google, Facebook, or Yelp.

The way I do it is go to the property records for the county online find the owner's info and then Google search their phone number.

So, you'd want to go into it knowing you were going to: go all out to beat your competition, have a distinctive property, stand out online, and have your return compensate you for the headache of running a little hospitality business.Does that help? 

I'd recommend starting to network with local REIA and joining community groups or online forums related to real estate.
