Frequently asked questions

How long do I need to stay for buying to win?

Often 5 years or more, because buying and selling costs are high. Try different stay lengths to find your break-even.

Does this include tax deductions?

No. Mortgage interest and property tax deductions only help if you itemize, which many people don't.
