Insight on current value of inlaw suites

[Chris Christianson]

We're about to start a large rehab project in the inner Minneapolis suburb of Golden Valley.  We've completely gutted the house which was close to 5500 sq/ft when we purchased it.  Thanks to the new fire suppression law in Minnesota, we plan to finish as close to 4500 sq/ft as possible but not more.  $10k for fire suppression isn't in the budget.  

Question is, this house was configured with an inlaw suite in the walkout basement.  We're not sure if we want to keep this one, possibly two, bedroom suite or lose the second kitchen and add walkin closets to the lower bedrooms.

Any insight on the value of inlaw suites
