A conventional loan is a loan that is not backed by the government (meaning that the government doesn’t make any guarantee that you will pay the mortgage), and therefore, carries private mortgage insurance if you put less than 20% down. Conventional loans adhere to guidelines set by Fannie Mae and Freddie Mac and are available to everyone, but are more difficult to qualify for than VA or FHA loans (you need better credit and a steady income, for example).
Take as much time as you need to find the right home. Then work with your real estate agent to negotiate a fair offer based on the value of comparable homes in the same neighborhood. Once you and the seller have reached agreement on a price, the house will go into escrow, which is the period of time it takes to complete all of the remaining steps in the home buying process.
