I am debating whether i should just fix the shower pan. or, rebuild shower as well just in case water leak is coming from shower walls. what do you think? 

Every area I know has gotten worse and worse and worse on it.Fifteen years ago,  when I was buying, rehabbing houses and holding, I oculd hire a licensed contractor and they were able to change toilets, faucets, even water heaters.

Regulation has slowed the market and made it harder to be an operator.I've never operated my Airbnb to its maximum efficiency because of the time it takes. 

This included installing new tile flooring at the front of the house to enhance curb appeal, upgrading the electrical panels for safety and efficiency, and putting on a new roof to ensure long-term durability.

High efficiency appliances were utilized including HVAC, light fixtures and water heater.The use of the accelerated depreciation strategy helps real estate investors to reduce the tax liability immediately which therefore increases their bottom line due to the offsetting of income.

About half of them because of heat, storms, fires and fresh water concerns.

Since electricity and water is included in our rent, we also have a clause stating that if the monthly bill doubles compared to the month-comparable bill from the prior year, then the excess will be assessed as a fee.

I'd like a systematic way, that's more efficient than my current excel sheet, to ensure I'm following up weekly with the same people while keeping notes etc.

I had a client buy an REO property and there was a water leak.

Water heaters need replacing, bank errors occur, tenants move out, real estate bubbles happen, etc.
