Do you think she either backs off or better help?

I have a older sister who is married. She is married to a family judge. They both work and the husband earns good money as judge. Event though they are not wealthy they manage to afford to travel internationally each end of the year for the holidays and during the year they also travel around the country. Also the husband likes to have the newest technology at home, a new cell if possible, new computer, etc. They both also like to eat out as a couple often. They both dont have children, the husband (my brother in law) have kids from a previous marriage but they are already grown up. My sister house is a nice house not very big though but nice, They both buy things for the house often either for the kitchen or the living room etc.

Anyway on the contrary me, my mom (who is elder) and my brother we had been living int he same house for more than 40 years, yes it is an old house and requires maintenance in many things, and the house is big. My sister before marrying my house was her house too. My dad passed away 11 years ago and my dad was always a simple guy, we never renovate part of our house at all, even if my dad could afford it. So now that my dad is no longer around, the incoming money is of course less, it comes from a pension my mom receives. My brotehr works but as independent worker, which means, sometimes he has work other moments he does not have, So at the house wwe try not to spend a lot of money on things we think it is not necessary or that cost a lot of money, just like the basics. We dont even travel often not even local like my sister and my sister never had invited not even my mom to go with her to local trip, like many children does with their parents. We are aware my house needs lots of repairs as it is an old house, but we can't do it all at the same time cause wwe dont have enoguh money to do it so so fast.

On the contrary if my sister and her husband needs some repair at their house, they do

it immediately without hesitation and just pay for the service. My brother he knows some thing around the house so if he can fix something in the house he does it to save money but on his time not right away, only if there is something he can't really do, we call someone to repair it. Like I said my house needs lots of repairs but we have to do it one at a time and not right away if there is enough money for it.

My sister likes to complain each time she visit us cause she acts as a house inspector to check what things in the house needs to be fixed and tell us: "These things need to be fixed, "Why dont you repair this or that", "the house is falling", "Check this, repair it". She complains but even though it is not her responsability , at least she could say like "I may help you with some money to repair this or that", nothing, she never had helped us in anything. The same applies with mom medical stuf
