Utilities were only water and electric.

In 2024, I hit $200k in cash flow from my properties. 

In this room, I would have preferred to rip out the existing paneling, and do the electric and new drywall at the same time.

Push the button and hit "print". 

I am building ground up so any contractors that do framing, plumbing, electrical, roofing, etc.

Tenants stopped paying electric and water.

Sorry one additional item I hit post too soon...The reason I asked about TIA is because you generally want to get a contractors opinion of cost prior to lease during that negotiating phase so you know how much that TIA covers and what you'll be coming out of pocket for.  

The big unknown is how deep the electrical and plumbing work will go.Also, with the attached 1/1 unit, I’m debating whether this could work as a long-term hold instead of a straight flip.

Since you would be dealing with maintaining a gas tank I would have all electric except a gas fireplace. 

We had to replace 90% of the electrical, created an open concept, primarily all new drywall, new boiler, new roof, etc.
