Making towbah from zina

Q: I am now 27. 10 years ago I had sex with a girl. She is older than me and non muslim, but intercourse didn't happen. I was even wearing clothes. I asked many times forgiveness from Allah Ta'ala. From that day, I went for hadd but the hazaraat told me it's not required in my case because any intercourse didn't happen. I am ready to do hadd. I feel very very very guilty of that and I face lot of problem in my life. I am struggling to get married so is it permissible do hadd in my case. Also sometimes I masturbate. I asked forgiveness from Allah Ta'ala again and again also for this I do hadd like hitting myself with a belt and burning myself with hot steel, pouring hot candle drops to my body. After repenting to Allah Ta'ala in this way again I masturbate. Is it permissible to hurt myself in such a way? I want to get married and want to do the jima' in the Halaal way. So I think Allah Ta'ala is expecting me to do hadd.

Inheritance

Q: When my father was alive he made an agreement with one daughter to pay the bond of his house. The house still remains his property according the agreement made by the two. Now after his death the daughter claims the house to be hers as the house is on her name because of the agreement. There are 9 siblings. 5 sons and 4 daughters. What is the sharia ruling on this?

Toilet leakage problem

Q: There was leakage in the washroom ceiling and then it stopped by itself. There is a washroom on the top floor. The water from the leakage has dried now. If somebody uses the washroom and wet feet touch floor and they walk around the house will the house be impure. The floor was not washed after the leakage water dried. Is whole house impure and I can't pray there?
