Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
This is what I am thinking. I understood about the 30 day rule; however, in that vain am I to understand that after a product is delisted for not making a sale, if it then goes on to make a sale while delisted, it will be relisted - PHEW, a lot of listings in that sentence, I think I confused myself - I think this is the case and sounds logical to me.

Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. [7]

Amazon Associates — Amazon sells millions of products (books, music, electronics, toys, and more) that fit into virtually any niche, so its affiliate marketing program is a natural choice for almost anyone. Comparatively speaking, its payouts are generous, too: They vary based on product type and sales volume, but commission rates start at 4 percent and can reach up to 15 percent for specific product lines. However, note that Amazon’s program is now illegal in several states (although there are some work-arounds).
Some businesses may be interested in adding other types of paid content to your website. This could include videos, podcasts, or any other material that would work with your site and help a business market itself. Always make sure that paid content isn’t too promotional. It needs to add value to your audience first and foremost, and not just present as an advert.

Understand how a niche website works. A niche website focuses on very targeted, specific information. The content must be specific, useful and interesting to your target audience. Successful niche websites get anywhere from 1,000 to 10,000 visitors per month.[5] You build content on a particular keyword, and you make passive income with Google Adsense or through affiliate links.[6]

The key is to make the class sound unique and irresistible. Don’t just teach a cooking class; come up with specialty cooking classes. You might teach a class on how to make artesian breads, or cinnamon rolls that rival Cinnabon. The possibilities are endless, and if you consistently offer educational and fun classes, you’ll have people signing up over and over again.
If you have a good idea for an app, and the skills to create it, then producing your own premium app can be profitable. However, with so many free apps available, it may be hard to convince people to pay. If you want to go down the premium app route, consider having a basic free version to encourage people to download the app in the first place. You can then provide the option of upgrading to a premium plan once users realize how useful the app is.
