Have them help you crunch the numbers and take all your expenses into account, including HOA dues, taxes, etc.

As far as keep or sell I'd crunch numbers.

I have crunched the numbers myself as this is a familiar town to us.

I haven't crunched the numbers in detail to know if they work.

Currently I'm working towards learning how to crunch numbers and analyze if this deal would be a good fit for me.

I crunch numbers and put deals together in both types of markets. 

In other words, if I want to invest in someone else's project or go in as a JV on a project that someone else has already crunched the numbers on, I need to be 100% confident in my comprehension of it.

My goal was to have that mortgage paid off as early as I could so that I could stash a sum of cash away for when my son begins college, have 100% equity to draw off of if necessary, and have a substantial cash flow from rent to offset his college expenses.This summer, I crunched the numbers again and realized paying extra didn't make sense any longer and the extra money in my pocket today was worth more than continuing to shorten my loan.  

There is a serious crunch going on right now.

After crunching the numbers on a spread sheet it really starts to snowball if I were to use my current savings rate and I am really excited in that kind of potential.
