Conclusion


This feasibility study highlights the viability of financing the Sovereign Downs project with 100% debt.


  • The property generates a gross yield of 6.71%, ensuring strong rental returns.

  • The total interest paid before rental income begins is $16,964, which is reasonable given full debt funding.

  • Over the long term, at a 7% annual capital growth rate, the property's value is projected to reach $1.08M in 5 years and $5.92M in 30 years.


With both strong rental yields and capital growth potential, this project presents a compelling case for investors seeking a fully leveraged investment with long-term appreciation potential.
