Unique investing question

[Christina Pope]

Short version:

My father recently passed at his owns hands and owned a beach house fixer upper. This has since passed to his girlfriend and I want to buy it from his as he had renovated half with his owns hands. It is one last memory of him and I am trying to find a way to buy it and once it’s fixed up, repay the loan with Airbnb or rental money. 
can anyone please give any advice?

Thank you
