Must have had a fat wallet to buy 65 properties and 300+ syndications in 10 years

Sounds like you skipped cap-x and just took a hit of "hopeium" instead. ya, that stuff will rot your brain and drain the wallet fast. 

Replacing old hardware with modern finishes like brushed nickel or matte black can also make a big difference.

Paint, flooring, landscaping, some new appliances, fixtures, hardware, etc.  

For hardware, go with brushed, nickel or brass gold.

They will be much more frugal if the bill is coming out of their wallet.

The main house is completed and as far as labor, I spent $40,000 on just labor and that includes everything from full gut demo to finishes.We are talking about a 4BD, 3BTH two story 2400 ft.² home with a bonus room.This was a full gut job, replaced…12 Windows (new construction)2 sliding doorsTook out all carpet throughout.Took out this ugly 2” thick tile from half of the downstairs portion.Removed popcorn throughout the entire houseTook one wall downA little framing workReplaced entry door 80” x 92”Drywall patchingSmooth drywall work50 recessed lightingAll electrical neededAll plumbing neededNew cement walkway instead of one walk to the front door I created two steps with two lights in each step.Install kitchen cabinets, excluding countertopInstall all three vanities3 bathtubs with one being a modern standalone tub in the masterAll tile work (bathroom wall & floor, kitchen backsplash)Installing of all hardware, faucets, showerheads, etcInstalled 8 single panel doors with hardwareAdding self-leveler after tearing out that thick tileNew LVP flooring throughout the entire house except bathrooms,all baseboards, trimsPainting the entire house, painting all the doors, painting the outside trim.Reframing the outside balconyReframing the fireplace to install new linear modern electrical fireplaceand they took care of the two trash bins.I mean, completely redone.The only thing that was not included in the $40,000 is landscaping, counter top cut and install and of course the ADU which I’m currently working on now.So my question for my fellow investors and contractors did I pay too much?

Still, some exist so keep your wallet at home for these.
