According to the sales person, I don't need to handle PH level, adding chlorine or even changing water due to sodium level they maintain. 

Quote from @Stuart Udis: The riskiest  strategy will be whichever new investment strategy the gurus come up with next to maintain a captive audience...can't wait to see what these creative minds come up with next.I don’t know what the next BIG STRATEGY gurus will come up with, but I do know it will include the following1.

This protects against potential claims and liabilities specific to the rental.For tax purposes, maintain clear records of rental-related income and expenses, allowing deductions for insurance, utilities, maintenance, and depreciation proportionate to the rental unit.

Focus on undervalued properties, prioritize high-ROI renovations, and refinance to pull equity for future deals while maintaining 20-25% equity.

How many weekends do you want to drive up north to find, purchase, setup and maintain an STR?

STRs also avoid automatic classification as passive if rented for seven days or fewer per tenant.To maximize tax benefits, maintain detailed logs of all hours worked on activities like tenant communication, cleaning, maintenance, and marketing.

This concerns me about the potential to maintain a solid tenant base and would likely cause a higher vacancy factor.

No one's perfect and honest mistakes happen and a PMC often needs guidance as to what level an owners wants to maintain their property.Wasn't trying to solicit your business,so I'll respond via DM about the rest of your questions:)

However, if you clearly communicated a $15K budget, I’d stick to that and ask them to discuss the overages with the contractor to find a resolution.As a side note, always try to maintain reserves for your properties.
