Need distance from in laws

So my husband and me are renting a house from his parents...they live 2 houses down from us. When we first moved in, it wasn't so bad but since our son was born a year ago my MIL has said obnoxious snarky things to me to put me down and even said I'm the reason her son is an a****** (not once, but repeatedly and she continues to) tries to control us and causes drama more often than not. So we decided it was time to get preapproved for a home loan. We started looking and MIL tells my hubby she is ready to sell us the house we are living in (it's a mobile home, not a good investment and I don't want to live next door to her because she always has something to say how she would do things or how we're doing things wrong) My husband tells her no, I want a stick built house. We put an offer on a house & we let them know. The next day, my FIL calls my husband and my MIL is upset because she is worriedshe won't see her grandkids (we'd be moving less than 5 miles away) and how she wants to subdivide some of their property so we can build on it. My husband has my back, understands I won't be around his mom without him present, agrees she's nuts. I told him no, may be we can move back here at some later time but we need some distance now. I feel like his mom is trying to manipulate him or pressure him into not buying a house so she can control him and keep him close. We ended up not accepting the counter offer on the house, and my husband knows I'm not happy and beyond ready to move. I've had it with my MIL and I'm about ready to lose my s*** . I really want to be moved away (even if it's only a few miles) by the time baby #2 arrives in March. Meanwhile, my parents live 45 minutes away from us and work may bring me closer to their area. They haven't pressured me to move closer to them, and they are very respectful and understanding. I feel like my MIL is being selfish and unreasonable about where we live and I'm not going to let her antics disrupt our plans. I fear if we find another house we really like and put an offer in on it, she will turn on the manipulation again and we'll be stuck here in this nightmare...
