The house's electrical system seems to be functioning properly, but given its age, we're wondering whether it would be beneficial to replace it entirely( I.e update the whole electrical system) My question is this: Would installing a new electrical system increase the value of the house and make it more appealing to potential buyers?

I like to point out to my potential tenants that I added insulation or replaced a FPE electric panel to show that I don't just slap lipstick on my properties to make a quick buck....I would think the same would be true of appraisers.  

It should not need much in the way of electrical, HVAC or plumbing.Can this be done for between $60-$100k?

Anything built before the 70s will most likely have issues with plumbing or electrical, and roofs last about 20 years, and should be permitted most the time on county websites. 

I'd feel just like Bugs Bunny and Yosemite Sam, looking at that pouty-pouty king in the dining room demanding, “Bring me my Hasen-pfeffer!!”

Here are some other facets of a rehab which may be more expensive, roofing, windows, HVAC. electric service exterior and interior.

I contacted the city of Edmonton and was informed that moving a mobile home is treated the same as building a new home, and all the following applies:Development Permit ApplicationCombined Building, Mechanical PermitBuilding & Mech Safety CodesWiring Electrical PermitUnderground Service Cable PermitElectrical Safety CodesConstruction Water Rates 44¢/$1000 Construction Value Sanitary Sewer Trunk ChargeLot Grading FeeTo my knowledge, unlike a new home, all we would be doing is reconnecting the infrastructure, and considering that no modifications are to be made to the existing plumbing, electrical, sewer or the lot itself, so do all those permits apply? 

The house needs all new electrical.  

I purchased a 1 BR 900sqft condo in 2021 with a depreciable tax basis of ~$275k and spent most of 2021 and first half of 2022 renovating the property (new appliances, flooring, painting, furniture, bathroom renovation, new kitchen countertops, new electric heaters, insulation, fireplace/pellet stove).

It is completely finished except for the electrical utility hook up.
