TVs
If a 4k UHD TV is the same price as an HD TV, buy it. However, if it's going to cost you more, it isn't worth it. No programming and few movies are transmitted in 4k, so it seems kind of silly to splurge on a TV with a function you can't even use. That being said, you should definitely temper your bargain hunting with a little television research.
Many inexpensive brands are so cheap because they aren't quality-made. In the long run, you're not saving yourself any money if you buy a product that's going to break on you a year or so down the road. That being said, there are still plenty of affordable TV options out there that won't disappoint you with quality issues.
Refrigerators
Today's smart fridges can play music and display weather but can't tell you what food is available or when it will spoil. Up to $4000 more for the same functions provided by your phone is silly.
When shopping for this product, stick to simple. You'll be much happier in the long run.
Steam Irons
With today's wrinkle-free fabrics and highly effective dryers, you'll rarely need an iron for anything an inexpensive model can't handle.
Plan to spend less than $50 when shopping around.
Closet Organization
Instead of splurging on custom construction that can cost thousands of dollars, create your own organizational system using affordable shelving, boxes, bins, and racks available from retail stores.
Your wallet will thank you when you only have to shell out $100 - $750.
Vacuums
A central vacuum system is convenient, but the benefit of not having to store and push around a portable one is overshadowed by the additional $1000 - $3000 you'll spend.
In this case, it's best to stick to simpler and more affordable options.
Countertops
Granite is beautiful, but it's also susceptible to cracks, moisture damage, mold, and staining.
For about the same price, choose quartz. Save money with brands like Corian.
Backup Generators
Unless you are medically dependent on an electronic device, the frequency of extended power outages doesn't justify the $4000 - $10,000 cost of an installed model.
Leave some wiggle room in your budget by purchasing a portable one, instead.
Exterior Paint
Liquid ceramic paint is thicker than traditional paint, costs about twice as much, and may not live up to durability claims.
Additionally, prep and application are best done by professionals, which adds even more cost. It may be more reasonable to DIY this project.
Ranges
If you cook on a regular basis, the additional BTUs on a professional style range may be benificial For most of us, they aren't necessary.
Instead, choose a standard range and save $1500 - $5000.
Built-ins
With some simple tools and minor hacks, you can make affordable freestanding units look built-in.
Save $6000 - $8000 and retain the ability to redecorate without needing wall repair. Seems like a win-win to me!
Microwaves
Circulation of hot air gives convection microwaves browning power.
However, unless you plan to use the microwave as your primary oven, you won't recoup the additional $700 - $1500 in purchase cost.
Interior Doors
Interior doors aren't exposed to the elements, so it's a good idea to try and save some money when purchasing them.
Instead of solid wood, choose less expensive solid core doors filled with composite wood. They're actually heavier than solid wood and provide superior noise blockage.
Cabinets
Custom means you can have anything a cabinet shop is willing to make for the price they set.
Semi-custom gives you the cost-benefit of factory production with customizable options. I know which one I'd pick!
Bath Tubs
Jetted and air tubs cost between $600 and $2000, plus installation and wiring fees. Additionally, a llack of frequent jet cleaning results in nasty gunk.
A soaking tub requires less maintenance and will save you a little without making you sacrifice luxury.
Lawn Sprinklers
Expensive to install and tedious to maintain, sprinkler systems aren't necessary for a beautiful lawn. Buy sprinkler hoses or landscape with native plants.
You'll save $1500 - $4000, but your lawn won't look any less amazing.
