Just here for some advice please help with whatever advice you have , related to purchasing a land or reconstruct the same old house and like try to make some profit out of it and than purchase land later years

Please help and be open for any advice , my house is old is the house where I grew up , the house is old and really needs a reconstruction which can also lead us to profit but the problem is our house is near the river not that near just like there’s the main highway right in front and than river so now every year it’s scary to live near our colony because of monsoon season and like I really don’t know it’s confusing . Should I tell my parents to invest on purchasing a new land or should we reconstruct our house idk earlier I was thinking to reconstruct the house and we can possibly get some payments every months by renting some floors and than we can stay on the top floor which can also make us profit and like make up with the investment done on reconstruction . And than buy a land later year . I mean what are your thoughts even the land the plots are getting expensive year by year idk sky rocketing like gold . Please share you advice and opinions
