Hi, i am a benefactor from the sale of my Mums house (their are 4 of us), i am currently residing in house. My eldest brother is the executor. House had been on market for 2 months. House originally listed for 700-750 grand, now is 660 (90 grand difference). There is a drainage easement on property (we actually have had no problem with it, no flooding), agent & brother say this is why price has gone down. Is this right? Why so much so quickly-shouldn't agent know all this from beginning?
