You can buy an old house and have it deleaded. Will cost maybe 15-30k, but you get a certificate from the state that can help with resell to people with young kids. Just because a house isn't certified deleaded doesn't mean it's dangerous. There is likely lead, but it can be encased in a safe way. FWIW our kid (now 3) we lived in an old condo (1908 build) not certified deleaded but recently renovated and then an old house (1919 build) that was certified deleaded starting at age 18 my months. Kid never had a detectable reading in his lead blood tests.
