Not firing a bad property manager fast enough.

Purchase price: $8,450,000 Cash invested: $2,600,000 Built in 1986 and situated on a 1.51-acre site, the boutique apartment community offers a unit mix of 30 two-bedroom/two-bath apartments.

You can offer a 40% discount on midweek stays.

 ...buy a 40-55 unit 1978-2000 value add preferably (town-house style) apartment complex in an A-B neighborhood.

It costs more now to replace/fix a car.

It may seem trivial for $3-4K/yr, but just consider it as a necessary action to be able to sell one day, otherwise you're likely to be in a serious bind later. 

All you need is a key box and key labels.

Again I have a fully executed contract.

Not once in a blue moon. 2.

It's a little bit tricky.
