Investing in Port Richey Area

[France Calle]

Hello Everyone, 

I am new here. I am also new to investing in real state. I am currently under contract to purchase property 9121 Gray Fox Lane, port richey. The inspection showed the house needs some repairs. It also needs a new AC and I will eventually need to replace the windows as they are 40 yo. Roof was changed 2016.

Could I ask for your expert opinion on what is a good offer for this house? There are no real comparable home  that have sold around.

Thank you and look forward to learning a lot about investing in real state.

France.
