This is a common issue, but having stricter cost control measures or a contingency buffer in place could help on future projects.

Would love to hear from other pros.For California investors with out-of-state properties, common asset protection strategies include using separate LLCs per property for liability isolation, though this incurs California's $800 franchise fee per LLC and administrative overhead. 

That is fairly common in small town mid-state areas where COVID shot up prices and then fell flat when rates skyrocketed over the last 12-18 months.Mid-Term rentals are always +/- depending on time of year and how the property is marketed.

Look at where you are advertising. 

Do I need advertising?

Thanks for posting however your video is essentially an advertisement for Bright Investor doing exactly what I did to generate my findings.  

This is a great website, the only thing that everyone have in common is that everyone invests in real estate.

Is this common to see?

But there is a lot of missing info that makes it hard to even begin.As other's noted, it could be any number of things, some more common than others.It might not even be bathroom related, i.e. a roof leak that is showing itself in a bathroom (but presumably this would be present when raining and shortly thereafter).Toilet, could be wax ring or the O ring that connects tank to bowl.  

Look at properties up for rent in the neighborhood that are advertising for the rent you are looking to achieve.
