I would compare to dorm style living.

Plus differences in management style and financial input.

I worked hard and sacrificed a lot as a 26-year-old RN to finally own a property and was excited to implement the strategies that I have learned through the biggerpockets community.

When I renovate a property I try my best to tenant-proof the property as best as possible without sacrificing cash flow.

It's not like in the US where you have the cash-flowing low appreciation Mid Western-style and the negative cash flow high appreciation Californian-style market.

I'm sure you can agree the property management style differs depending on the answer!

One can also or should also take into account the emotional/mental and life style factors that may come into play too since everyone has different preferences on what they'd like to do with their free mind / time space.I think for some the 14 hours is more than acceptable however if a person was willing to trade that 14 hours and perhaps reduce it  down to 20-30 minutes of calls/emails per month by hirining a professional manager it may make sense as well depending on the cost.

I installed a cassette style mini split on a ~600sqft project of mine.

For example, I'm interested in a 3/2 ranch style house built in the 1960s.

Talk to people doing that style of investing - but instead of asking them the technical know how questions - ask them their opinions of their experience.
