Contractors are not cheap , if you have the skills , tools and time do what you can yourself , you will save big money . 

I’m all for doing the work myself but if there are tools to automate some steps I’m game. 

There're a lot of automation tools that can streamline the Airbnb listing and management.

I don't know about your state but mine (TN) has a lookup tool that will show you the agent's original license date, the brokerage incorporation date, etc. 

The fact is if you use NN the way it was designed, direct contact, regular calls, texts or emails with people you are contacting is essential.

Could you share what tool or website you use to determine the potential rent amount/vacancy rate?

Over here in the Reno Tahoe market we have developed a tool that has properties sorted for income potential, condition, asset class, and cap rates.

It's a tool. 

Most have a Market Analysis tool that will sort through listings in a specific area and give you yearly numbers for occupancy, average rate, total revenue, etc.Only use VERY SIMILAR properties for comps: Properties you're using for comps should be almost identical to the property you’re analyzing.

The tools that are offered are exceptionally useful and user friendly.
