More than likely you would need to give up around 70-80% of equity and own a minority - some deals would allows you to buy it back at a set price as well. 

Alternatively, happy to be a resource, run analysis on deals etc.

But the most realistic goal I have is to get better at analyzing deals.

For those, each has its own LLC because I need to segregate investors in different properties (in other words, the ownership is different so the entity has to be different) and because our lenders for those size deals require single purpose entities.But if I formed a separate LLC for each of the 700+ properties that I’ve purchased in my career (all of the houses and small multi), I’d need a full-time legal team just to handle entity administration.  

How did you find this deal and how did you negotiate it?

Although most such fund operators only deal with accredited investors directly, you may also be able to find some among the crowdfunding sites.  

Then when you see some tractions or close some deals, you can reinvest in your website.

If it is a direct lender you are able to work to find more favorable terms because they usually determine their terms on a deal by deal basis. 

Usually the type of work has to be dealing with the real estate itself, not just providing a service that is applied to a part of the house/building. 

Some new investors think of it as a no-money down deal and given those other costs, it really almost never is.
