You can get 2.6% on a 12-month CD from Ally, but fully agree: with anything else, you will be taking a risk. You didn't mention a specific time frame, but you said you sold your old house, so I assume you are looking to buy immediately? If you had said you were 5 or 10 years out, you might get a different answer.
You may also be doing better than you think. Given your price range, I assume you aren't looking for a coastal house. While I'm in Ireland, I have a house-worth of CD's sitting back in the US. We will be returning to the Houston suburbs, which Zillow reports are gaining at 1.x%. So, I can reinforce my correct decision to not take risk with short-term money by also seeing the icing on the cake that I am actually beating local housing price inflation, too.
