The best course of action is to contact a lender , get pre-approved and then hire a buyer's agent. If you need any recommendations, feel free to contact us at (978) 360-4743.
Your credit score is acceptable your and your down payment is great. The last piece is your income. The monthly payment needs to be a certain percentage or less than your monthly gross income.
Talk to a mortgage broker and see what they can pre-approve you for. If you need names of some good mortgage people send me an email.
However, check with someone who can advise you on finances as to whether you should put that much down. You typically want a "rainy day fund"--often with the goal to cover at least 6 months of your living expenses (so, typically, about half or more of your annual salary or wages). You definitely don't want to use all or most of your liquid cash. Further, with interest rates as low as they are it may not make sense in putting that much money in if you absolutely don't have to.
Congratulations on the solid credit score, by the way.
Hope that helps.
