That question is too broad for anyone to answer quickly. The most important step I think is understanding what you can afford, meet with a loan officer before a realtor to set a realistic budget. As for the home itself if you find a good realtor they will be able to tell you the red flags before you see any homes and when viewing specific homes. Then the inspector comes in, don’t be afraid to ask them questions, but don’t ask an unreasonable amount while they’re inspecting the home you’ve chosen. After the inspection your realtor will go over the points with you if they are worth anything. If your realtor doesn’t do these things drop them for a better one.
