Feeling stupid for being so unhappy with new house

I feel so ungrateful. So my partner and I were recently living in a 2br 1ba apartment an hour or so away from family. We had a really good deal on it, but there were always things we wished we had (like in-unit laundry, yard, for example). When I got pregnant my parents were so excited and asked if we wanted to move in with them. We would live in the main house and they live in the in-law unit (which they have been living in for years since I moved out). The main house was being rented by family friends. We gladly accepted. We wanted to be close to home, especially to my parents who are getting older and have had significant medical issues in the last couple years, and the opportunity to have a yard for our dog and an actual house not apartment was something we couldn’t deny. So we worked out a deal where I would pay the mortgage price not rent price which would be double, plus any repairs and bills (internet, electric/gas, sewage, water, trash). I’ve already been paying our family’s phone bill. Well we had NO idea how bad the condition of the house had gotten. The renters cracked the tub, broke the toilet, every single sink was leaking including the shower, a piece of the stove handle is broken, they painted everywhere but did it in such a messy way that there is paint on the cabinets, windows, and even mismatched paint. The house needs a new roof and gutters, the downstairs flooring is so old with glue everywhere from their rugs, the main flooring is really messed up from the renters (there’s stains and dents everywhere), and one of the rooms smelled SO bad because they had 2 huge dogs and we had to rip up the new carpet there just because of the smell. There’s more I could write but it’s just so much stress. Part of it is my parents fault for trusting them so much as family friends and not being good landlords. So again, one of the conditions was that I also take care of house repairs instead of paying rent. This is a house that will eventually be passed down to me since I’m an only child/will etc. Well I’ve been moved in for a week or so and I just feel so depressed. I’m not happy here. I almost wish I could go back to renting. We live in California so buying a house is really not affordable for us, at least not right now. We also live in an extremely expensive tourist city, so even though this house is in such bad repair and is on the smaller side, it’s still worth around $800k. Idk if it’s my hormones or what but I’ve already put almost $2k into the house and not happy at all. Everywhere I look I find something wrong. I know my parents would just call me ungrateful if I expressed any of this to them. I guess I’m just looking for someone to tell me I’m being ridiculous, I know I’m so lucky to have supportive family and have a roof over my head. I just feel in such a funk over the stress and unhappiness.
