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 property does have heated radiators through out each unit. everything is separated for each unit electricity, gas, and window units in each property.

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).

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

It is important to find something that was properly maintained, with modern plumbing, electrical and roofing. 

We've seen cases for example where clients want to send their brother or cousin to do electrical work that they aren't licensed for.What I don't think would work is to have a ticket come in, and then reach out to a client so they can shop around for plumbers.
