Need suggestions on purchasing a property

Hi All, We are planning to buy a builder floor flat(reason : we get more land share than buying an apartment). Budget within 1.5 to 1.8 cr My salary : 44lacs My husband's salary: 64 lacs We both have purchased two houses in our home towns in tier 2 cities. Together we both have a loan of approximately 44 lacs. We are not closing it because of tax benefit and also those loan accounts are OD we are getting approximately 7% interest. Till now we didn't have a plan of buying any property. We just had a plan of doing sip in mutual funds which will give more returns. But now we are feeling like buying one. Because both of us are doing wfh and our daughter started going to school. Parents are also staying with us.

Is it a good idea to buy a house or stay in a rented property, have some savings for the next 10 years or so and buy with full cash?
