What level of finishes do you use?

[Trudy Hoekstra]

I'm working with a semi-experienced flipper (3 years of about 4 houses a year) who is giving me advice (my first two flips flopped). She typically does top-of-the-line for the neighborhood and then prices at median price. She says this sells fast. For instance, if 2 out of 5 houses in the area have dual pane windows, she puts in retrofit dual pane windows. If some but not most houses use granite countertops, she uses granite. If most places have tile tub surrounds, she'll do tile with some kind of border/accent/design. This goes against the advice I've read in books saying that a rehabber should stick with what the average house has in the area.

What level finishes do you use? If 2/5 of houses in the area have dual pane windows, would you replace unbroken single pane windows?

Thanks for your advice! I overdid my last house and I'm so afraid she's telling me to make the same mistake again, but I know I need to trust my mentors.
