Automatic investment selection is built into the platform. Investors set their criteria for the loans they want to invest in, and when one becomes available, the system invests your money for you. After that, you have 24 hours to perform due diligence on the loan. PeerStreet is the most transparent and elegant real estate crowdfunding platform I’ve used. Unfortunately, it’s for accredited investors only at this time.
When you create a website, you can become an affiliate of several major e-commerce platforms, the most popular of which is, of course, Amazon. Your affiliation partner pays you a monthly commission, based on the number of referrals you’ve generated from your site (trackable via a code). Their behavior on the affiliate partner’s site is also relevant, i.e. purchases obviously matter more than simple clicks on affiliate links.

You also get to see specific details about each loan, including what the borrower is using it for, the state they live in, how long the pay-off period is, what the monthly payments are, and what rate the borrower will pay. It helps you get a better picture of what type of risk you’re exposing yourself to, and you get to take more control over your investment.
I own several rental properties in the mid west and I live in CA. I have never even seen them in person. With good property management in place (not easy to find but possible) it is definitely possible to own cash flowing properties across the country. Not for everyone and not without it’s drawbacks, but it seems to be working for me so far. I’m happy to answer any questions about my experience with this type of investing.
If you're looking to get started in real estate, look at a crowd funding solution like RealtyMogul. It works similar to LendingClub - you commit as little as $5,000 towards a property. When the property is fully funded, you become an owner, and will receive your share of the earnings and appreciation in the property.  Check out RealtyMogul to learn more.
