You're asking someone to spend a lot of time and energy to share what they've spent years - maybe decades - learning and developing.

This can be a huge time and cost saver, especially if you’re managing the property remotely or using property management.Energy Efficiency: New buildings are generally more energy-efficient, which can be a selling point for tenants and lower operating costs for you.Builder Warranties: Many new builds come with warranties, providing some peace of mind for unexpected issues within the first few years.3.
