I never go off of a flat percentage on anything, I analyze the costs to get to a specific return I target and analyze the risk that is involved. 70% may be an initial metric to see if it is even worth pursuing, but every deal should be evaluated independently based on costs, time and risk involved.

Are there specific reasons you don't want to rent them out (e.g. bad previous experience with a tenant)? 

They can evaluate your specific case and guide you through the process effectively

I mean in general what sort of expert should I try finding first, but if someone has specific people in mind who deal with the UP that works for me too.

One of my first questions is always - "what are your specific goals?"

For us, the only time we pay contractors upfront is when it is for really specific jobs like full HVAC and full Electrical jobs, and these are somewhat large companies with vans and trucks, so we know that these guys aren't running anywhere with our $3k upfront payment. 

Be specific...."

I couldn't find anything too specific on the site.

So, the first question they usually ask a PMC is about fees - instead of asking about services and HOW those services are executed.EXAMPLE: PMC states they will handle tenant screening – what does that specifically mean?
