The actual act of Buying a home is the easy part - we Realtors do it every day and walk first time home buyers through the process all the time.... from Offer to Close of Escrow. In any intial meeting we can explain the process and/or you can buy a how-to book, and of course we keep explaining every step of the way, and prepare you for each next step. It may seem complicated if you've never done it before, but it really is not if you're working with a professional.
On the other hand, getting to know your own wants and needs, getting comfortable with what's available in your price range, and then finding the right home for you.... well, that's tricky part. No seminar will help you with that, you really just need to see as many properties as you can.
Once you've got a decent idea of what's out there that's in your price range that you like, then I'd recommend going out with a Realtor. Not only have we seen thousands of homes, we've seen them through many other Buyers and Sellers eyes, and can help point out things that might help or hurt re-sale value that might not otherwise occur to you.
The last step before the offer is asking your agent to prepare a "CMA" or value report on the home you are interested in (taking into consideration all it's features) so that you are comfortable with the amount you choose to offer. The rest of the process again is something a good agent can help you through as you go.
