プロのヒント

If you are close to the 20% down payment threshold, consider whether it makes more financial sense to put 20% down to avoid PMI versus putting less down and investing the difference. Compare: PMI cost per month times expected months until PMI cancels, versus the expected investment return on the withheld capital. In a high-return investment environment, using leverage and investing the difference can come out ahead, especially if you expect rapid appreciation to eliminate PMI quickly.

難易度:初級

ご存知でしたか?

The concept of standardized LTV limits in US mortgage lending was formalized through the creation of Fannie Mae in 1938 and Freddie Mac in 1970. Before standardized secondary market requirements, LTV limits often capped at 50-60%, requiring large down payments that restricted homeownership to the wealthy. The introduction of mortgage insurance — FHA in 1934 and private mortgage insurance in 1957 — allowed LTV to rise to 95-97%, fundamentally democratizing homeownership in America.
