Combining two rooms

Probably about $75,000

No chance at $10K. There will be a big difference if the walls are load bearing and if you need to move some electrical. I think you should assume it is at least at the high end of your range ($75K sounds pretty high though). Ask the broker if they know anybody with that apartment line that did it and ask them. Good luck.

if you remove walls you'll potentially have to redo all the floors or live with an obvious indication of where the old walls were.

You will probably need permits from the City and you'll need to check with the board how they handle construction projects.

I would think ~25 if this is in manhattan. You would need an engineer/architect letter stating its ok and no walls are load bearing, and licensed and insured contractors.

i agree with others who said you are likely to need to repaint, do floors, moldings etc. . .so that adds additional costs.

why would you make a 2 BR a 1 BR. You'll only reduce the value. I just looked at a 1 BR that the guy made into a loft and could not believe the stupidity.

I'd talk to your realtor & see what their opinion is on the resalability of your plan; you don't want to shoot yourself in the foot !

Original poster...thanks for the responses, helpful. BTW, not converting a 2BR into a 1BR, basically converting a 2BR with a small alcove (a BR, in NYC speak) in a normal sized 2BR. Appreciate the responses.
