Hi J.,
How exciting! But what a big cleaning job you have ahead of you. I'm wondering, regarding the carpeting, can you pull it up? I imagine if the house is old, you have hardwood floors underneath. Although, they might be damaged from all of the animal excrement. I feel pulling up the carpeting is the most effecient way to really sanitize the house. I think bleach/water is fine for the all of the tiled and linoleum. Will you paint? I find that painting really helps get the previous tenants/owners smells out. Regarding the yard, I can't help you there, I'm clueless!! Good luck!
PS - what kind of dresses do you sew? I'm really interested in learning how to sew since I buy my daughter lots of handmade dresses on ebay/etsy.
