Change windows?

[Priscilla Z.]

Working on my numbers for my next rehab project and I need some input. I haven't had to change windows in the houses I've rehabbed so far, so this would be a first.

There's nothing wrong with the windows, except that they are old. They are the ones with the thin silver frame and the thin glass.

My partner and I are debating it, he says there is no need to change them since they are in good condition, and I want to change them since we are planning on changing all the A/C ducts and the inside and outside A/C units so changing the windows will be a plus and make the house more energy efficient by keeping the cold air in.

Advice? I know it's a big expense and it will be a big item on my estimate sheet but I think it's worth it considering the price range I will be able to sell this house in.

Also, I've been pricing them out on home depot but I'm assuming that just going directly through a company that installs windows I can probably get a cheaper price on the windows than the prices I am seeing at Home Depot?

Any help is greatly appreciated :)
