So person A invested 200K, person B invested 100K.

I'd be interested in hearing people's thoughts about or experiences with the La Más Backyard Homes Project https://www.mas.la/affordable-adus.

I would not label crowdfunding as risky overall (plenty of people get conned in person as well) but I agree with @Chris Seveney and others who have said that due diligence on the sponsor/operator is paramount.

There is also the idea to rent out a room as an office to another person as well.Trying to find info on this question online has been tough, so I thought I'd ask all of you!

I got an impression that they want to buy the entire property using the exchange funds, and then after the fact write in the other person as a co-owner.

Then you can develop investor personas and really hone and refine your marketing campaigns to attract the best investor candidates for your product type, duration, etc. 

You most likely will not have to accept that person as there is an incredibly high correlation of a repeat offense after a first one.

@Rinee John de Leon is right each person walks a different path and what works for person A won't work for person B.

If you’re not sure if your processor issues 1099s, be sure to check their terms of service.You paid the person a total of less than $600 during 2019The person who worked for you is a corporation, and you made payments to his corporation.

As a new investor, I'd be happy to use this person as it would be a way for me to learn the construction portion of a reno project for future projects.
