There are a lot of things to consider when getting ready to buy a home. The first is, How much can you afford for your monthly payment?. Also, a portion of that payment helps you on your taxes so if you are paying a little more than before it could be far worth it in the end. You have to consider taxes and Insurance and monthly maintenance as well. This all needs to be worked into your monthly budget.
Once you have that figured out contact a lender and go ahead and get your loan in process. Make full loan application so that you know where you are financially. Are you going to need some assistance from the seller on closing cost? Are there credit issues that you need to correct immediately and of utmost importance how much are you going to put down on the home regarding your loan?
Remember if you can put 0% or more down you will eliminate Private Mortgage Insurance.
When making application your lender will help you out in getting all your financials set in place to purchase. This also will give you the leverage when working with your REALTOR® in finding your New home and negotiating with the seller.
