Buy a home or keep renting: the 30-year decision

Comprare casa o restare in affitto: la decisione da 30 anni · Family · Advanced

The case

You pay €950 rent and have €60,000 saved. A house you love costs €240,000: with a 30-year mortgage the payment would be similar to the rent, but the €60,000 would almost all go to down payment and fees. Stable but not bulletproof jobs, two young kids, and in-laws pushing: 'rent is money thrown away'. How do you make the decision?

Pagate 950€ di affitto e avete 60.000€ da parte. Una casa che vi piace costa 240.000€: con il mutuo trentennale la rata sarebbe simile all'affitto, ma i 60.000€ finirebbero quasi tutti tra anticipo e spese. Lavori stabili ma non blindati, due figli piccoli e i suoceri che spingono: 'l'affitto sono soldi buttati'. Come prendete la decisione?
