The $750K Condo Scenario
A $750,000 condo represents a mid-range Brooklyn or Queens 1-bedroom in 2026—competitive neighborhoods like Cobble Hill, Astoria, or Long Island City. The buyer puts 20% down ($150,000) and finances $600,000 at the 2026 30-year fixed rate of 6.875%.
| Monthly Cost Item | Condo (Buy) | Rental |
|---|---|---|
| Mortgage / Rent | $3,953 (P&I) | $3,200–$3,800 |
| Common Charges | $700 | included in rent |
| Property Tax | $700 | included in rent |
| Insurance | $75 | $30 (renters) |
| Total Monthly | $5,428 | $3,230–$3,830 |
| Monthly premium to own | +$1,598–$2,198/month | |
Year-by-Year Equity Build
Equity comes from two sources: loan principal paydown (guaranteed, happens regardless of market) and price appreciation (variable). The table below uses conservative 3% annual appreciation.
| Year | Principal Paid Down | Appreciation Gain (3%/yr) | Total Equity (excl. down payment) | Property Value |
|---|---|---|---|---|
| Year 1 | $8,000 | $22,500 | $30,500 | $772,500 |
| Year 3 | $25,000 | $69,500 | $94,500 | $819,500 |
| Year 5 | $43,000 | $120,700 | $163,700 | $870,700 |
| Year 10 | $96,000 | $257,800 | $353,800 | $1,007,800 |
| Year 20 | $229,000 | $604,400 | $833,400 | $1,354,400 |
Total equity column excludes your original $150K down payment. Add that for total net equity. Appreciation is illustrative and not guaranteed.
By year 10: The condo buyer has $353,800 in equity gains from paydown and appreciation (plus their original $150K down payment), for a total net position of roughly $503,800. The renter has zero equity.
5-Year, 10-Year, 20-Year Total Cost Comparison
| Horizon | Total Condo Cost | Total Rental Cost | Net Equity Gained | Condo Net Advantage |
|---|---|---|---|---|
| 5 Years | $325,680 + $20K closing | $210,600 | $313,700 | +$178,020 |
| 10 Years | $651,360 + $20K closing | $421,200 | $503,800 | +$412,240 |
| 20 Years | $1,302,720 + $20K closing | $842,400 | $1,133,400 | +$1,108,280 |
Rental assumes $3,500/month constant (in practice rent rises; this is conservative for renters). Condo cost includes all monthly payments. Net equity includes down payment. Sale costs not deducted.
The Down Payment Opportunity Cost
A fair criticism of home buying is the opportunity cost of the $150,000 down payment. Invested in diversified equities at a historical 7% annual return, $150,000 grows to:
- 5 years: $210,400
- 10 years: $295,000
- 20 years: $580,000
This is real opportunity cost. But consider: the condo at 3% appreciation grows from $750,000 to $1,007,800 in 10 years—a $257,800 gain on a $150,000 investment in an asset leveraged 5:1. The leverage amplifies returns substantially. Most disciplined renters also do not actually invest every dollar saved vs ownership costs—the forced savings nature of mortgage payments has genuine psychological and financial value.
When Renting Beats Buying a Condo
- You're planning to move within 5–7 years (transaction costs don't amortize)
- You have a rent-stabilized apartment well below market (give up this advantage carefully)
- You need maximum liquidity for a business or investment opportunity
- Your income is variable or uncertain
- The neighborhood you want is significantly above your affordability range
When Buying a Condo Beats Renting
- You're staying in NYC for 10+ years with a stable life situation
- You want inflation protection—your mortgage payment is fixed forever
- You want to build generational wealth and potentially leave the property to heirs
- You value stability: no lease renewals, no landlord decisions, no possible displacement
- You want rental income potential: many condos allow subletting if you relocate
