Now, let me say, obviously, it doesn't happen like this on every deal and I had a list of buyers I've cultivated over 3 years so it helps to have real buyers in place BUT still its nice to know you're in a business that can generate that kind of cash that quickly. 

The 15-year note is nice because every month about $1000 goes directly to principal with the downside being the high cost.

Besides that everything in the house else looks well so far.What repairs are absolutely necessary, what is nice to have and what is no need?

You provide the WiFi password because you're a nice guy and don't mind letting someone else use it.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

It is known that the house flipping industry is growing and that to be successful in the business of flipping, you will want to buy homes at a discount in order to have nice margins when you go to sell. 

On one side I am an active real estate investor with experience and (knock-on-wood) some nice properties. 

FHA is such a nice option for first-timers that many think it's a first time homebuyer program (it's not), but once you start getting into multiple rentals and this "nomad" strategy, FHA is rarely the model match.

Repairs - Because the house was just remodeled completely I added in 3%Vacancy - This townhome is in a hot area for rentals, less than 5 minutes from a top hospital and in a nice area overall.

Sounds nice.
