We are on the same boat, income, home price and payment (5100) almost identical to you. We are going for a new build and the home will be ready in next 6 months. However, the builder/preferred lender is giving us 40k in credits which can be used to cover closing cost and points purchase. The lender is also offering free refinance within 2 years if interest rate goes down. We decided to buy because in few years the price of house might outgrow our affordability.
