We had an ultra high efficiency furnace put in a few years back when we were living there so the yearly heating costs are fairly low.

I was reading the "Who pays $1300 for rent" thread and many of the replies mention ultra high rents in NYC & SF, etc.  

I looks like last year Home depot came out with allure ISOCORE which is apparently different from Allure Ultra.

Every major city in the US is setting records when it comes to the building of luxury apartments.  

We could have reduced the negative of the project by keep the budget of rehab ultra low or just selling out of the project but we went over budget on the rehab by adding a new bathroom and converting a room into a bedroom.

That just wouldnt be my personal choice.4) Depends if its a flip or a buy and hold, luxury living or low income housing, etc, etc, etc.Hope some of this helps though I know I didnt answer as concretely as you might have hoped. 

I help investors and luxury buyers and sellers.

Currently working on a triplex in Strawberry Mansion 

We don't have the luxury to have real estate that makes sense to invest in across the street.  

Its in my notes somewhere from my broker courses.I handle all types of properties: luxury condominiums.
