Is renting really throwing money away?

No. Most early mortgage payments go to interest, not equity. Renters who invest the difference can build comparable wealth, especially over shorter time horizons.

How long do I need to stay in a home for buying to make sense?

Most financial planners recommend at least 7 to 10 years. Transaction costs and slow early equity buildup make shorter holds risky compared to renting and investing.

What is the rent-to-price ratio and how do I use it?

Divide annual rent by the home purchase price. Above 5% favors buying, below 3% favors renting, and 3-5% is a neutral zone where personal factors matter most.

Do mortgage tax deductions make buying clearly better?

Usually not. Since 2018 the standard deduction is high enough that most homeowners no longer itemize, which means the mortgage interest deduction provides zero additional benefit for many buyers.
