Buying vs. Renting

Cash Buy Strategy

Buying with cash eliminates interest costs but carries a high **opportunity cost**. By locking up capital, you miss out on potential market returns (S&P 500 average 8-10%).

Pro: Zero monthly mortgage, instant equity, and high bargaining power.

Leveraged Buy (Mortgage)

Mortgages allow you to use "Other People's Money" (OPM). Leverage can amplify your ROI if home appreciation exceeds the interest rate.

Tip: A 20% downpayment usually avoids PMI (Private Mortgage Insurance).

Loan Architectures

Fixed-Rate

Your rate never changes. Predictable and safe. Best for long-term stays.

+ Higher initial rate than ARMs.

ARM (Adjustable)

Lower rate for initial 5-7 years, then adjusts based on the market.

+ Risk of payment shock later.

FHA / VA

Low downpayment (3.5% or 0%) options for qualified buyers.

+ Stricter inspections & upfront fees.

How to Save & Optimize

Recast vs. Refinance

Recasting keeps your rate but lowers payments by applying a lump sum. Refinancing changes the rate entirely.

Tax Deductions

Mortgage interest and property taxes may be deductible (check SALT limits).

The "Golden Rule"

"Never buy a liability thinking it's an asset. If it doesn't put money in your pocket or save you more than it costs in opportunity, it's an expense."
