House was moldy

House had a huge mold problem when I moved in, never hired any professional mold remediators either, just put a dehumidifier in the guest bathroom and had an hvac guy "look at it". Listing says "brand new house" but it's a clearly flip on a very old home. Side door was bolted shut (not advertised) and the water pressure was terrible. Also whole house is one narrow hall with a huge glass paneled front door at the end and no window coverings on it so everyone can see down the entire common area (kitchen, living room, and dining room) day and night. Wouldn't recommend staying there if you have allergies or like privacy.
