A "perfect brrrr" is hard to come buy with today's financing.

In a perfect world all defects would be removed prior to closing and there would be no claims. 

Acquired on the market, this 4-unit rental needed a full remodel, creating a perfect BRRRR opportunity.

The next guests will almost certainly be upset that the hot tub is out of service for their stay and are likely to injure my near perfect streak of 5 star ratings which will injure search rankings and possible lose me bookings.

It's not a perfect system, but past behavior is a great indicator of future behavior. 

Instead ask them what they would like to get in a perfect world.

I'm only bringing this up because you mention 1) rent is always paid on time; 2) neighbors have no issues; 3) The tenant's are hardly there (which means less property wear and tear) and 4) I will also assume becuase of the first 3 here, that your property is also being cared for...... seems like picture perfect Tenants.... 

Perfect! Ive

Start with a basic system and improve incrementally it will not be perfect.  

This is the perfect place to start learning and building connections for your real estate journey.
