Any tips to buy the house off him ?

[KangarooKenny]

I really, really want to keep the house. Any hint and tips to have it go my way ?

Well, you’ll need to divulge additional information if you want any practical advice ….

Do you mean buying someone out of a mortgage/ joint ownership or just buying outright.
Either way you will probably need a mortgage or further borrowing on an existing one, all based on age, income, term, assets etc etc.

Can you afford it?
