The only way I see this being possible is if I become a PM, collect all fees, take my cut, then redistribute to the owner.

It looks like cut & paste.    

We have now cut our liquid capitol in half.  

going to depend on age of house how extensive updates, etc, etc, etc, there is no short cut number that will work 

Like anything is sales (and you are in sales even when you are trying to buy a property), the less clean cut the deal, the more likely it is to get rejected.

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?

While you may not make significant passive income renting the other side or the other three units, you can probably cut your living expenses in half or even live for nearly free in a 4-plex.If I had to do it all over again, I would have taken this approach at your age and purchased a 4-plex every year or so with minimal down payment.

The realtor tried to talk me up to at least 175 but… that’s cutting a bit into my profit margin and I’m not that eager to buy it because that’d also be my biggest renovation project.

You are already losing money on it so you should either cut your losses and sell or be comfortable losing money on a monthly basis with the expectation to make it up on the sale down the road (see you're in FL so you might need to wait a few years).

Mortgage companies, heirs, Bob's construction company that put a workman's lien on the property, Credit card company, etc etc... exception being local municipality liens ( grass cutting, demo etc.)
