I need help!

I'm stumped. It has always been my dream to have a condo unit. Finally it was built since January this year! And it's just there, waiting for me...
- I hired an interior designer, check!
- Our design has been approved by the engineering department, check!
- True, it took me a while to get a contractor, but check!
- I have the funds to actually implement it, semi-check! (Bye to Europe for now... sniff!)
- Dad will help me out in the project (supervision wise), check!
I've been agonizing over this back-and-forth "sell or keep" question literally a thousand times. Why sell?
1. Our house in BF has 4 bedrooms. Come July, it will only be Dad, Mom, and I left to live there. Oh, and Ginger. The point is, we have a lot of space.
2. The monthly expenses of having a condo is huge. I have my amortization, monthly dues, electric/water bills, blah, blah, blah. I can afford it, but I will need to sacrifice some luxuries.
3. I want to be close to home so I can look after my parents. Monitor what they eat (as I promised my sister)... and just be with them because I love them to death.
4. I can use the profit to pursue my other dreams - like travel the world!=)
5. Other reasons you can think of?
Why keep?
1. It's MY DREAM.
2. I'd like to give independent-living a shot. Heck, I'm 27 and I still live with my parents. Okay, that last statement did not sound convincing enough. Heck.
3. I've always wanted to have my own "gallery" of artworks... it's the most perfect place!
4. It's near my office. It's near the prime malls of Metro Manila. Location, location!
5. Other reasons you can think of?
I'm stumped. Wish I'm the type of person who can decide with just a snap of a finger. Why is life getting so complicated by the minute? Or am I just complicating it? Hmmm... where's my Magic 8 Ball...
