In our area, the housing authority does annual inspections to (mostly making sure the landlord is keeping up the units) review the tenant and the landlord. 

While the staff at RTR do try to work with you and accessible, it's important for potential investors not to be swayed solely by glowing reviews and comments.

A national buyer would review the BPO and maybe do some brief online research, but would not typically not know, as in your example, about the sewage issues or extent of interior rehab needed.

You need to review the assessment record for your property as there may be errors. 

Also consider all lenders will require to review your insurance when underwriting a loan and it's likely a violation of your existing loan documents to let the properties go uninsured even if they didn't require insurance escrows. 

They said they only review categories every couple of months so I patiently waited and called again.  

In 30+ years we've been sued 1x (legal blackmail over a tenant's drunken trip/fall) which the insurance company settled for $1,500.00).We've been using some privacy tactics to keep our names off the county recorder and the target off our backs.Further, we review our insurance coverage and premium annually, just to keep on top of any changes.As with all insurance, it seems to be a waste of money... until you NEED it!

Frankly, I'm surprised by all the positive reviews. 

It's a good time to review markets, but living in China there are a lot of other closer, international markets that could be options as well.

Rentredi seems to do it all but the reviews for it say there are a lot of bugs and a lot of hidden fees.
