Like others have said, there is always room to trim the rehab costs, but I wouldn't say you "over improved" simply because you left some cash in the deal after refinancing.  

All wood trim was painted BLACK by her in her apartment.

Specifically the current competitive rates for new construction trades and materials (e.g. foundation, framing, plumbing, electrical, drywall, trim carpentry, painters, tile work, brick layers, roofers). 

Dead branches over the property line are the responsibility of that owner . if you trimmed them you would be trespassing on anothers property

Or maybe after a few years you decide one or two are just your "problem child" and you want to sell them to reduce your headaches by trimming the fat. 

You can do that with construction adhesive or you can let it float and secure it with nailed stair-edge nose trim, which you're going to need anyway to cover the edges of the laminate.

The cost to completely paint the interior of a house (walls/ceilings/doors/trim) will run you $3k to $5k alone.

I'm searching for a quality tree trimming service in the St.

I found the property, financed it, and spent a half-day doing the below list of fixes which amount to pretty much nothing if you ask me: installed new white trim/base boards under the kitchen countersSwept and moppedCleaned counters, sinks, bathroom, bathtub, windows, and so forthNew caulking here and there.Cleaned backyard a little. 

This house does need about 15k in cosmetic updates (paint, trim, door hardware, cabinet paint and hardware, counter tops, appliances).
