She then tells me that her dad is a home builder of luxury homes, and that she is used to high quality and homes in perfect condition. 

For paint i use home depots BEHR Premium Plus Ultra paint with primer.

The condo unit is on the outer circle of two circles of units that surround an old Mansion with a pool that sits atop a hill.

The only problem was that it was in a rough neighbourhood, and condo fees were over $2,000 per month.There's a unit in a luxury building close to where I live listed at $4,500,000, and condo fees are $4,500/month!

Not all double-pane windows are created equal, and you could end up with a buyer who wanted the ultra high end ones than the ones you have - and result in no value created.I know there are glass replacement companies out there, if the window frames are still good.

Or, go ultra-modern with some dyed concrete.

I found some guys out in CA that do exactly this, but on multi-million-dollar luxury properties where the margins can be much higher.

I have an offer in on my first deal: an elegant old mansion conversion and negotiations have stalled.

@Matt Maluchnik, I live in a luxury apartment (for 2.5 years now), have good credit, an experienced partner that does 60 flips per year, and liquid cash to put down and was also told by 2 different HARD MONEY lenders that I am not eligible to receive a loan from them because I don't own my own primary residence that they could use as collateral, LoL.  

I think that Luxury Viny Plank (LVP) or the slightly more expensive Engineered Viny Plank (EVP) would be better choices.
