NPR had a few aspiring homeowners check out online calculators that help you understand at what monthly cost it makes more sense to to rent versus buy a home.
The calculators and resources they had them use were:
- Is it better to Rent or Buy? by The Upshot from the New York Times
- Rent vs. Buy from Trulia
- Renting versus Buying a Home from the Khan Academy
Great starting point resource for prospective buyers.
