Fueled by a robust education system, a supportive business environment, and an enviable quality of life, Austin continues to magnetize companies and is poised to lead tech innovation for years to come.

I’m also wondering if it’s a function of business structure.

Secure the unit for the dog and your tenants safety - meaning all doors and windows should be functional.

If the appreciation is due to great climate, no room for further development, robust economy, etc) then the long term appreciation is more likely. 

No on-site office, nearly autonomous functionality.

A robust medical community also. 50%+ of the population here are renters. 

Tenants don't see any difference between a den and a bedroom as long as it's a functional living space, so you won't run into any issues thereIt's unlikely that you would have to pump out the system more than normal with standard usage, but one thing I would recommend is to always ensure your septic alarm is fully operational.

No on-site office, nearly autonomous functionality.

Renters, ESPECIALLY those who know they are only looking to rent for a finite period are generally focused on function over aesthetics.

I'd prefer the bulkhead as it has more functionality, but not sure if that would satisfy code to make it a "legal" bedroom.I am hoping to refinance the property after I make the improvements to get my money back out, but that would definitely require the additional bed and bath to meet code and be considered legal.If anyone has the answers here, could point me in the right direction of where to find them, or just has any advice in general, I'd really appreciate the help!
