., major systems like plumbing/electrical)Full Gut/Studs Down: $85-$120 per sq. ft.Luxury Finishes: $150+ per sq. ft.For ARV (After Repair Value), you’re absolutely right—it’s all about comparable sales ("comps").

@Jorge Caceres Is this with electric baseboard heaters or  heat pump/minisplits.

I would be more hesitant if they were added on (new plumbing and electrical) vs just upgrades to existing.

I have a bachelors in Construction Managements and run substation electrical jobs for a living while my wife is a stay at home mom with the kids.

My husband did 90% of the work himself, only using contractors for large electrical, plumbing, and construction projects.

The company managing our property as a vacation rental was unable to get the power turned on in our condo for months because we had to get the meter switched into our name with the electric company (which is much more difficult to do in CR than in the United States).

Get a degree in Finance or Engineering and you'll graduate with a world of possibilities. 

@Anade DavisHi Anade, You’re on the right track with reaching out to your survey and engineering company—they often have strong connections to local contractors.

@Phil SheltonYou would need a civil engineer to provide a drawing to get submitted to zoning and get a permit if it passes zoning is most common This also depends on the road - if it’s a state road forget it as it will take a year to get approved and cost a fortune - if it’s a local road process not as cumbersome but don’t expect this to happen quicklyIn some instances you may have to prepare sight distances etc to make sure it’s safe to add a curb cut

Many properties will need specialized attention, especially with plumbing, electrical, and historical elements.
