Upscale master suite addition
Who doesn't want to wake up in a five-star-hotel-quality suite with an attached spa bathroom and a kitchenette that affords you coffee and pastries before facing the world?
Once you see the price tag, it won't just be the coffee keeping you up at night.
For a super-deluxe master suite addition -- which adds square footage and uses only top-dollar materials -- the average cost is about $232,062, according to the report.
That's 460 nights at a posh resort with enough left over to raid the minibar.
In years past, this project was "sort of a trend in vacation homes" that migrated to primary dwellings, Alfano says. Sellers can expect to recover about 52.7 percent at resale.
Your buyer can purchase a newer house with the same features as part of the original floor plan that "probably lays out better anyway," says Loren Keim, author of "How to Sell Your Home in Any Market."
So while the next buyer may appreciate your luxury accommodations (which could even tip their decision in your home's favor), chances are they won't want to pay the full tab for your remodel.
