Anybody buy building and then apply for historic designation for tax benefits?

[Peter Fokas]

I have come across a unique property - 1890 colonial farmhouse that has a separate carriage house that has a 1 bedroom apt that is rentable. The house has been nicely kept but it needs new floors and definitely  paint jobs. Would it be worthwhile to apply to get on the historic registry to take advantage of the tax credits?  My goal is to buy and hold and live in the house while rent the 1 bedroom apt. Was thinking perhaps the tax credits would make it feasible to buy an old house.
