Do I just go for it?

[Jillian Kemmerer]

Hello everyone! This is my first original post- though reading and commenting has been fun!

Over the last week, an unexpected deal has fallen in my lap! It’s a cute place, with probably about 30k worth of work to do. However, I could sell for easily that much profit, or hold and rent out the two units for a great cash flow after expenses. 

Seems too good, right? But even my husband is on board- which is usually NOT the case. 
 Should I just go for it? House has been vacant for almost 3 years, so I know there could be a lot of surprises. But it was winterized before they left, and the issue that caused the family to leave has finally been settled in court, and should be handled by end of summer. 

Also- HELOC or Hard Money, if we're planning on holding?
Thanks, everyone!
