Secondly sister I understand what you are saying and it can be difficult dealing with older people who are more set in their ways and feel comfortable where they are and want to remain there for the rest of their lives. Although your mother in law is your husbands responsibility then know that if something happened to your mother in law whilst your husband and her were not in good terms then he will forever be in utter regret as we only have one mother in our lives and we should try our best to ensure we keep them as happy as we possibly can. Even if it means making minor sacrifices to what we perceive as our own "happiness".
We should also consider that we we think is best for us is not always necessarily the case. I know from many of the things that have happened in my own life that when things turned out differently then you eventually see the wisdom behind it later on. Similarly you have made effort to make her see sense and leave the rest now to Allah and ask of him to do what is best for you and whatever happens after that will be what is best for the both of you.
However that is not to say that you will not be able to get a property later on. It may be that if you waited due to pleasing your mother in law that Allah will give you something better later on. But also realise that this is an amazing opportunity for your husband and you to get immense rewards by making your Mother in law happy and looking after her. By making a little sacrifice you will gain something far greater. Much of the time we look at what will benefit us in this world without realise that what we gain in this world is short lived and temporary whereas what we gain in the next will benefit us forever!
May Allah enable us to prioritise the rewards in the next life over little gains in this world. Ameen
