All make careless mistakes. You accidentally under tip the waiter. You lock your keys in the car. You press "send all." It happens to the best of everyone.But some little mistakes can create big problems, like when you're buying a home.

To help you out, we have pinpointed some common ways home buyers botch their property-purchasing prospects so you can sidestep these snafus at all costs.

Flying solo

If this is not your first time on the home-buying, you might think: Why hire a real estate agent to hold your hand? Well, first, let remind you: It's generally free to use real estate website portals. And whether it's your first home or your fifth, you probably want a professional to help guide you through the making sure the deal is up to snuff.

Negotiating power

Be careful what you say when you're viewing a property at an open house or home showing. For instance, if the listing agent hears you say to your spouse, "I love this house, and it's way under your budget," the seller might try to play hardball when you try to negotiate on price. Keep private conversations private.

Credit score

Unless you're buying a house with all cash, you mortgage still has to go through underwriting to get approved. Since this process typically happens shortly before closing, you don't want to do anything while you're in contract that's going to hurt your credit score. That includes buying a car, boat, or any other large purchase that has to be financed.

Trusting a verbal agreement

Some home buyers don't realize the importance of putting everything in writing. Unfortunately, that can come back to bite you, hard. For instance, let's say a seller promises he'll replace the water heater before closing. Well, if it's not agreed upon in writing, the seller is not required to do it.
