I am getting a lumpsum estimate for things like electrical, plumbing, but I am not sure what the cost is for. 

The main reason/difference between this and the delivery of electrical energy is that the losses of transmission of electrical energy are generally less than 1-2% (that's why we use electrical transmission methods over long distances, generally speaking). 

I think flipping is the way to go on this project since it’s my first deal which has always been the plan but very grateful for some guidance. 5 weeks of tear out, wall paper removal 🙃, new electrical, deck supports, HVAC install…we start putting it back together!

You mentioned a career change, I think going into the trades like plumbing and electrical are great and you can make good money doing those, but I think you may be taking on too much by trying to do that right now.

Another consideration, @Jay Hinrichs, is whether the electrical infrastructure at the property can handle it. 

I did a lot of repairs myself but also hired a few skilled contractors for things like electrical work and plumbing.

If the house has the right updates for electrical it is a very in demand area for Section 8 tenants as well.

There are exceptions - some properties are set up such that installing a few electric baseboard heaters might be possible to save on the gas bill - but i would still just shy away if not metered separately at the outset.  10) do shop for a lender and compare (usually pretty standard but there can be some fluctuation) - dont fall for the ones that sound too good to be true - there are gimmicks out there - big bank or reputable broker should do you fine.  

You may not occupy your apartment without electric service except during brief interruptions beyond your control.

Here's what I've learned:Inspections Are Non-Negotiable: Always get a full inspection, but don’t stop there.Plumbing & Sewer: Have the plumbing and sewer systems checked specifically, as these are common problem areas in older homes.Electrical System: If the inspector flags any electrical concerns, bring in an electrician during the inspection phase for a detailed evaluation.
