Lle19*57, I'm so sorry for your loss. The short answer to your question is yes, there's a home for every need, and if we look carefully enough and long enough, we will find one that meets yours. We can figure out how much you'd be able to pay monthly and work from there to find out what price range you'd want to focus on, and then start writing Seller Financing offers. We've done a few rent-to-own deals in the past few months, and some sellers are willing to consider it, but it's not something that they generally advertise. You'll have to ask for it in your offer, and be prepared for most of them to say "no, we need the money right now".
It's important to remember, though, that WHERE you live is, ultimately, not going to make as much difference in your kids' lives as HOW you live. Be sure that this move is the best thing for you, too, hon; kids thrive when their parents take care of themselves.
Keep in mind, too, that writing an offer on a property also means writing an Earnest Money check -- money that you deposit with the seller's Realtor to prove that you're serious about buying the house -- and that's generally $500. The Realtor doesn't deposit it until you have an agreement; it's deposited once you both sign the contract. Also, you always have the right to walk away from a property if your inspection finds that it needs more work than you can deal with. However, you still have to pay for the inspection (usually $200-300) even if you don't buy the house. (And please, please get an inspection. It's the best money you'll spend.)
I wish you the best of luck no matter what you decide. If there's anything I can do for you, please don't hesitate to contact me.
