Whether you should re-design your interior space completely, spruce it up or start all over is a BIG decision. It is part of a complete evaluation of your house or apartment's needs, your budget and your commitment/ desire to stay in place.
Last week, I was part of a group presentation with my husband Mark (who is an architect), realtor and a mortgage broker. Lots of fine points were covered...Some essentials:
If you are a renter, you must know or have to find out how much you want/can should do to someone else's property. Painting, carpeting, redoing (though not structurally) a rented apartment or house used to be common. In fact, I've done painting, built-ins, window coverings in rentals for myself. Maybe the landlord will help pay, or maybe you're confident you'll be there long enough to make it worth the expense.
Planning to move in a year or 2? Consider that you should be able to take the portable stuff with you: furniture, rugs, accessories, even blinds or drapes, chandeliers, track lights, and all of the artwork, accessories, etc. When you build in you will be leaving: recessed lights, kitchen or bath cabinets, entertainment units and closet built-ins. If you are crazy in your self-confidence and/ or get very good advice, you can be creative, unique and daring and HOPE your buyer will like your ideas.
Paint is the most changeable thing you can do. It's "just a coat of paint" and you can have fun with it. Wallpaper is very much in style again and if it's good quality and not too unusual, it would add to the uniqueness and design quality. Carpet is pretty reasonable too. It's much less than hard-surface floors and if you are leaving.....consider the carpet option.
Biggest changes will involve hiring an architect and a remodeling contractor for just gutting rooms or kitchens and baths. Consult a realtor to see what's being done in the building or in the neighborhood and decide if you will be pricing yourself out of the market.
If you OWN a place has not been worked on in 7-10 years, its likely time. I think that the longest any of my clients had gone was in the 25 year range of (realistically) NOTHING. Right now, I am redoing MOST of the parts of a bathroom in an 80 -year-old house. I told them that prospective buyers will look at this "before" and it will keep them AWAY. (Should be done in March, and photos will be posted). A number of other spaces have been redone over time....
The longer you are staying, the easier the budget considerations will work themselves out, since only hard surfaces last forever (tile, hardwood) as well as built-in lights, etc. Done well, all this shows consideration for the property and that's a good thing, not a strange thing.
If you are committed to stay, conditions don't much matter - do it for your enjoyment. Plainly, you are considering the next guy: remodel Vanilla and if it's for you, go from Daiquiri Ice or Rocky Road
And---IF it's too much work or too much money, or both, and you are not going to make this your dream home or something close to it, maybe it's time to look around and (literally) "get moving"!
