If I'm not getting my principal back, personally I really don't care about whether they were theoretically accruing interest on day one or not.No platform is perfect, and investors have to do their own due diligence on Crowd Street just like anywhere else.

You can almost always pay down principal if you have surplus cash and want to pay off the note early.

It should have the names and addresses of the principals.

Negative cash flow of $816/month plus the cost of the $60K loan and expenses.If you could mortgage the property 100% at a 4% mortgage ($280K) the interest, no principal,  on that would be $933/month.

: What are the components of a mortgage, is it only interest, principal, tax and insurance?

Ensure the principal or deal sponsor has a strong resume.

Since you didn't finance the purchase of the house itself, it is likely that the partner will offer to pay you principal + interest rather than a share of the profit (at least that's what I would do).

In this scenario:  1) I would borrow somewhere between $1,000 and $4,000; 2) Lender would get all of the monthly payments until they were paid back in full (principal and interest); and 3) repayment in full would take between six months and two years.Of course, such loans would be secured by the property.  

I've helped 3 couples  in the past 3 months house hack duplexes since they're friends of family and extremely happy with their purchases as their total outlay is between $0-$400/month so when you include principal pay down, they are living for free. 

If you intend to pay off the loan sooner then the commercial is the loan to choose as you will be pushed to pay more principal down faster.
