The real estate market is on the rebound (for today) and people are buying and selling properties in many locations across the U.S. That means a lot of opportunities for professionals who know how to navigate the legal, financial, and commercial aspect of real estate to build up a stable of clients as a side business idea, especially if you begin to scale your sales hiring and build a team of reps working to help you close more deals. If you consider yourself an expert in the subject, it won't be a walk in the park (hehe), but you can earn significant additional side income as a home-based consultant.
This business is good for photographers, as they will already know a lot about improving an image via specific editing. It can also be good for those with extensive skills in editing software such as Photoshop. Finally, it's good for those who use social media extensively, as such a person will be able to offer creative editing services to help customers build their online brand through unique visuals.
Renting out an extra room sounds like a pretty smart idea. App development also sounds like a pretty good idea, I found the link you left about how Benny Hsu made 30000 in 30 days quite useful. I have always been unsure on how you can start a blog but the 6-part video that you left was very helpful to understand how better. I also liked the idea of car flipping. I think it could work quite well especially here in Hawaii. I have personally found that dividend investing to be very useful in increasing income. I was also completely shocked that you can be paid to be someone’s friend. That is crazy that you found that.
