The steps are fairly easy, get approved for a mortgage loan, then find properties in the price range you are approved for, contact whom is selling the home you like.
There is a lot to consider when buying a house. Unless you have vast experience in buying and selling real estate, you need a real estate pro or an attorney.
If you do not want to involve a realtor than look for houses that are for sale by owner. You can find the house that you want to buy and make an agreement with the homeowner to have an attorney write an initial agreement to protect your down payment or earnest money.
Know the area you're interested in and prices. Once you find something there will be lots of paperwork, you may want an attorney to help you review the paperwork.
Step One is the Purchase and Sale Contract including the sale terms and conditions. Next, have an inspection by a licensed contractor. Third, choose a closing agent.
