Do you really think that your question can be answered using Astrology. No, it is not possible. Buying a house is just like buying a costly gold chain. If such sort of things could be predicted by any science, there is no need for planning, investment and accounting etc. Astrology can only evaluate your horoscope based on your time of birth and can only show you possibilities of potential problems ahead. Similarly good times could also be evaluated and whatever you do when times are good will yield you good returns too.
Nobody can own a house, why? Simply because you have to pay the taxes to the govt. to stay in your house. What does it mean? It the King who owns everything and you pay a tribute to him. We call it Government. That’s all.
