If I get it sparkling clean quickly, attract a great pool, show it smoothly... 

That is the million dollar question.

Based on this, it sounds as though this is an attraction option for my wife and I that have a part-time small business as well.

I walked into this house with around 25k in equity and its turnkey in a good neighborhood that will attract good renters.

Because of regulations, a bank could face millions of dollars in fines if specific policies aren't followed and they get sued.  

His focus is in the high end of the residential market(> 4 million). 

Again the goal would be to provide them with an attractive package, while still allowing me to profit off the property and preserve as much of my capital as possible?

As well, I find that many consumers are ill informed and don't really care about the windows... they see all the nice shiny, new things/rooms in the house and if the windows are letting light in, they often don't give it a second thought.A contractor once called me up as he was putting a large addition on his brother's million dollar plus home in Northern Virginia.  

No construction manager or project manager with a degree will understand the minds of an investor, we act quick and fast and usually have a 2 week timeline, whereas projects in millions will have more slack time to act on things, in a 2 week period, you have hours to solve the problem.

Start out and run your business like a business and plan to make millions and you will. 10X from the start!
