I am worried that my property expenses will leave me in the red because of the current costly housing market.

You didn't mention each of those markets, but there are cities in those areas that are worth researching or learning a bit about.Best of luck as you get started and again, feel free to ask more questions or reach out personally if I can help you navigate and learn BP and get started investing.Best - 

You will see all over the classificados where people want section 8 housing, but not enough rentals to provide it. 

Another house might be a single family home with a fenced yard and LVP flooring and be more suitable for allowing pets. 3.

Like should I start at the roof and go down, or start under the house and go up?

None satisfied their very specific requirements; so i suggested that I build them the house they wanted. 

Interest is low on the house and has a great cash flow, always has been.

They can also sue you for damages if they incur temporary housing costs, feel you discriminated against them, etc.

This house is not updated.

Again, not an "at demand" a person can readily get, especially not in Victoria.
