Your first step in answering your question is to meet with a local and trusted mortgage broker, they can prequailify you at no cost. This will tell you what price range you quailify for, what your monthly payments will be and how much you will need for a down payment and closing costs.
If you feel comfortable with these numbers, your next step should be to meet with a buyers agent, you should be able to hire one at no cost to you as they get paid their fee from what the listing agent states in mls and received it at closing.
This way you will have someone to guide you through each step of teh buying process. they can provide you with listing sheets and addresses. If you can find what you are looking for at a good price, then by all menas you should buy. If you are not comfortable, then you should wait.
