Building a home has a ton of potential perks. You can live in a house with the layout and design you want, and you don't have to shop for a place or duke it out in a bidding war.

Building a home comes with costs you wouldn't have to think about when buying a home, though. Building is often more expensive than buying, and while you may decide it's worth the cost, it's good to be prepared. Here's what you can expect to spend:

You'll notice some of these expenses vary drastically. That's because costs can depend on factors such as where you live and which materials you're using for your home.

You may also spend money on clearing land to build your home on a plot, repairing an existing foundation, or structuring your home so it's built on stilts.

Building a house based on your budget

Remember, the actual cost of building a home will be based on several factors, including where you live and whether you're hiring a production builder or customized builder. You'll also save money if you build the home yourself rather than hire someone, but you'll need a license and a special type of construction loan.

You may be able to afford to build a home for $100,000 if your house is 1,000 square feet or smaller. You should be able to fit two bedrooms and one bathroom in a 1,000-square-foot home.

Can you build a house for $300,000? Chevron iconIt indicates an expandable section or menu, or sometimes previous / next navigation options.

You might be able to build a 3,000-square-foot home for as little as $300,000, but that's leaning toward the conservative side. In a 3,000-square-foot house, you can fit four or five bedrooms and three bathrooms.

Frequently asked questions about building a house

Is it cheaper to buy or build a house? Chevron iconIt indicates an expandable section or menu, or sometimes previous / next navigation options.

It's usually cheaper to buy a house than to build one. There are some exceptions — for example, you can probably build a tiny house for less than what you'd spend buying one.

Costs depend on several factors. For example, you could spend less building a relatively small, modest home in a low-cost area than building a larger, luxury home in Los Angeles or New York.

What is the most expensive part of building a house? Chevron iconIt indicates an expandable section or menu, or sometimes previous / next navigation options.

Framing will likely be the most costly part of building your home. It will depend on which materials you use, the square footage of your home, and how many stories and rooms there are. According to HomeAdvisor, framing can cost up to $50,000.

Do I need a special type of loan for building a house? Chevron iconIt indicates an expandable section or menu, or sometimes previous / next navigation options.

If you can't afford to build a home entirely in cash, you'll need a construction loan. You'll probably need a 20% down payment for this loan.

You can choose a construction-only loan, or a construction-to-permanent loan that rolls your construction loan into a regular mortgage once the building process is complete. If you plan to build the home yourself rather than hire a contractor, you'll need an owner-builder construction loan.

Building a house can be expensive, but that doesn't necessarily mean you shouldn't take that leap. Just be sure you're comfortable with the costs before you start the process.
