If you're anything like us, you're probably constantly on the prowl for ways to make life at home sweeter and more luxurious -- while, not incidentally, boosting your property's value and without breaking the bank.

Luckily for you, you can indeed have it all. Here are some big-impact improvements you can pull off that can be surprisingly cost-efficient -- especially when you take into account the return on investment. Because it's all about the ROI and living the good life.

1. Spruce up your patio

Average cost of a new patio: $3,007
Increase in home value: 3% to 4%

It's no secret that more homeowners regard their backyard as an extension of their living space. So it shouldn't come as a surprise that outdoor kitchens and furnished patio areas alongside a fire pit are increasingly popular.

Irene Medina, a real estate agent at Medina Group Real Estate in Coral Springs, FL, says an outdoor kitchen is "a big plus in homes [priced] from $350,000 and up." This can be anything from an area in the patio with a built-in grill and sink to a full-blown kitchen.

Low-hassle option: Don't have the money for an all-out kitchen? Try adding french doors that open to the outside. This simple change will make your home feel lighter and brighter, and will appeal to potential buyers -- all for an average cost of $879.

2. Add a hot tub

Average cost to install an above-ground hot tub: $321
Increase in home value: 1% to 4%

"Having a hot tub on the property is a great selling point if the home doesn't have a pool or a water view," Medina says. If the property has a built-in pool, a hot spa attached to it or nearby could also go a long way, she says. Prices run the gamut, depending on how elaborate you want your spa to be. At the upper end, these babies can cost thousands, once plumbing, electrical, and the tub itself are factored in. But they don't have to.

Low-hassle option: Don't want to heat things up that much? Potential buyers are simply looking for a backyard oasis. Consider a simpler (and cheaper) upgrade by adding a hammock surrounded by lush landscaping -- your costs will start around a whopping $30 for the hammock. (Cost of fresh caipirinhas not included.)

When it comes time to sell, any special extras that can paint a picture of leisure and relaxation out back can be an incentive for those in the market for a new home. Leisure is a good thing, right?

3. Get smart

Average cost to install a home automation system: $1,282
Increase in home value: 3% to 5%

These days, smart intercom/doorbells that can show a homeowner video of a visitor at the door (and use remote communication) are becoming the Main Street version of the urban doorman. Smart garage door openers, security systems, and thermostats are also becoming more common.

Not only will these smart gadgets help you feel more secure in your home, they are also a big draw for the tech-savvy buyer looking for innovative and practical home features, says Mike McGrew, treasurer for the National Association of Realtors and CEO of McGrew Real Estate in Lawrence, KS.

Low-hassle option: Consider a small splurge on just a Wi-Fi video doorbell. For as little as $100, you'll have a fancy amenity that can provide convenience and some peace of mind.

4. Add an in-law suite

Average cost of a basement remodel: $18,618
Increase in home value: 5% to 10%

Real estate agent Nancy Itteilag of Washington Fine Properties in Washington, DC, says she recently was "thisclose" to selling a home, but for one major obstacle: The property wasn't fit to accommodate the prospective buyer's au pair.

In her market, where double incomes are at an all-time high, there's big demand for homes with an au pair suite, in-law unit, or a flexible living space (often on the lower level of a two-story house to maximize privacy for both au pair and family). So while the initial costs seem quite high, they could pay off in spades when it's time for a sale.

Low-hassle option: If you already have a finished basement, you're in luck. Want to give the feeling of privacy without doing a total remodel of the space? Throw up some temporary walls. For just over $200, you'll have an extra bedroom instantly. And if your basement has a separate entrance, it's all the better -- it can double as a living space that can be rented out for extra income.

5. Create a wine room

Cost of a wine cellar: Starts at $4,000
Increase in home value: Varies, but can be as much as 2%

We're not talking about a dark closet where you hide your best reds (although those pay off, too). We mean a next-level wine space -- possibly furnished with a small island or table -- for entertaining guests and igniting conversation.

For some wine collectors, this room is becoming more of a showpiece than simply a repository to let wine age. Accordingly, in high-end homes, these cellars are also moving from the lower level to upper floors -- often housed in glass walls and under LED lighting.

While Realtors agree that a wine room can increase your home's value, this home improvement should be thought of first and foremost as a treat just for you. Because you deserve it!

"Wine cellars are a bit like swimming pools. They come in all shapes and sizes and costs. And the next folks that look at your house may want nothing to do with them," McGrew says. "So do a wine cellar because you want a wine cellar, and don't try to justify it by an increase in value when you sell."

Low-hassle option: Carve out a space in your home to display a few decorative wine racks and a wine fridge to keep bottles chilled and ready for entertaining. You could create your own wine enclave for as little as $200!

6. Change up your flooring

Average cost of installing new flooring: $2,853
Increase in home value: 5%

It might not sound sexy, but flooring is also high on the list when it comes to features that pay off in a big way. Whether it's made of reclaimed hardwood or picturesque tile or features heating, it can set the tone for the whole house.

Want to step it up even more? Heated floors in common areas such as kitchens and bathrooms are a nice amenity for cold winter mornings -- and, of course, add a sweet touch of luxury to your home.

Low-hassle option: If you're looking for a home makeover on the cheap, consider new carpeting in neutral colors, which can go a long way in pleasing prospective buyers. The best part? The price tag, with an average cost of just $1,491.
