I worry that if I try to compete in too many directions, I'll wind up with a service that technically competes in all fields without actually being very competitive, if that makes sense.I hear that you like the blind review process, and can definitely work to take some inspiration from Airbnb's setup, but can I ask what specifically bothers you about the star ratings?

Best part is you wouldn't even need to find the buyers, more money if you did but good chance you don't need to.Anyway give it some thought & good luck to you as it's a much more sophisticated way to learn.

I am an engineer turned to technical sales from Tennessee. 

Technically, it is not required to buy or sell property. 

 @Nancy DeSocio,Hi Nancy,If the property is in Cranston  technically there is no overnight parking on the street allowed longer than 2 hours between 1:00am - 7:00am. 

I've been on the LP side of a few deals, and generally avoid them because while things may start out well, a few years down the road things change....The only LP deal I've entered after I got some degree of sophistication was a commercial deal something like this:1-It was a good deal, rehab of an existing building with a planned tenant.2-I put my money in, and it accrued 6 or 8% interest.3-The first series of payments were 100% return of capital and of interest, with a 95/5 split (95 to us LPs)4-all payments after that were 70/30 (70 to LPs)5-If building is sold after all capital and interest is returned, 70% of net proceeds go to LPs.The thing I really liked about it was that my exposure was at 0 after 2-3 years in.

If your investment will make you more interest than you are paying for debt it technically makes sense to invest. 

@Or Basan - Well, no, not technically. 

His first job out of college was a technical sales job $75k plus commissions- in his best year there he made about $160k.

I'm pretty sophisticated and I can't rely on the Stock Market even with puts, calls, day trading or margins to make this kind of money "Safely"!
