I think in the last few years the syndications cleaned up.

We added value by repainting interior, new floors, new roof, resurfaced the pool, added a fence for privacy, upgraded the landscaping, sealed and painted the exterior, added central A/C with new unit, upgraded the irrigation system, added gutters, added security cameras, added hurricane proof front and rear doors.

Your house looks very clean and new, but lacking a little character with no artwork. 

I hired a virtual designer for a few thousand dollars and after giving her dimensions/walkthrough she had a buy list and floor plan ready in two weeks.

If so, it will be nice and clean since you will be their agent.

How long for properties to be turned over with just cleaning and when repairs are needed?

The tenant fails to pay their last month of rent, moves out, and leaves some cleaning and repairs.

My heart sank to the floor when I received a text message from them telling me they will not be moving forward in the purchase.

Clean the above up, add to them, etc.  

I think the days of a fresh coat of paint and some laminate floors with nice landscaping isn't going to get the job done these days.
