1. It is a UK Gov legal requirement to have your registration number on your website, is there a reason you are lacking this fundamental requirement?
I found 27 separate companies for their different locations registered under Kexgill, so I am not sure how that would work with what you are describing. Did you find any discrepancies or a cause for concern about Kexgill?
My first concern is just that. Why don't you have your registration number on the website? What are the possible reasons for not listing your registration number? Registration numbers are for identification purposes. You said it yourself, you found 27 different listings. Which one is this? You can have 1,000 subsidiaries but your holding corp. still has 1 registration number.
It's not what "I" am describing, it is what is REQUIRED by the UK Govt. for EVERY company. Just seems dumb NOT to use it (if you have it).
Other concerns?
Why are they crowdfunding if they have 27 other companies and thousands of units? Isn't crowdfunding for startups? Why are they using an ICO? What purpose does it serve them? Why not equity? Why not any other traditional financing or crowdfunding?
What are they using the money for? Just more property? They are a successful company that wants "me" to pay for their property (which they will own) and then they will "maybe" give me back a 6%? So I can get my principle back in 15 years?
They do have a "30 Year Bounty" so maybe they are just really, really, long term thinkers?
To be honest, I was excited to see a student housing project but the deeper I look, the less appealing it is. Who know? I know it's not easy to be under heavy scrutiny and maybe they can answer all this stuff. I would even give them more leeway except for what you said, there are 27 companies so again... why do they need MY money?
