All being performed at a reasonable rate for a small business owner/investor. 

I wouldn't sell one of the rentals to do so if they're good performers but I'd for sure use every drop of cash flow to do so. 

Are there sites other than AirBnB and VRBO that you would recommend that have a more extensive screening process? 

A developer typically will not buy a piece of land without getting site plan approvals, zoning, LOI's from tenants,etc.

I have a seller financed performing note I would consider selling. 

I've had success, and have also been burned on properties that reach this so-called 2% thing - which really is not a rule (the 1% rule isn't a "rule"), it's just one of many metrics used to evaluate an opportunity and the performance of an investment.  

@Jaz PatelIf you want lower risk then I suggest either performing notes or being a hard money lender. 

Have you looked into getting these properties to perform better before making another move?

You can find them via BP and meetup sites.

Just wasn't sure if there might have been a site that may have held the answer.
