Estimate = (median $/sqft × your sqft) + bed/bath/lot adjustments. Bed and bath adjustments use Appraisal Institute / Fannie Mae standard rules of thumb (~$15K/extra bedroom, ~$20K/extra bathroom vs. a 3bd/2ba baseline; half-bath = half adj). Lot premium is a $1.50/sqft heuristic beyond a 6,000 sqft baseline — accuracy varies sharply by urban infill vs. acreage market. Quality, condition, year built, and HOA are not modeled here.

Rent + invest vs. buy + own — backtested

15-yr rolling history · S&P 500
Property type:
Upfront capital committed (both paths): $113K = 20% down + 3% closing on a $493K home
BUY + OWN
Median ending wealth $433K $264K real
Net gain on $113K upfront: $320K
Range: $433K → $433K
Wealth = home value (appreciated at 3%/yr) − remaining mortgage − 6% selling cost. Gain = wealth − upfront. Leveraged appreciation on full $493K asset comes from the 20% down.
RENT + INVEST
Median ending portfolio $967K $653K real
Net gain on $325K contributed: $642K
Range: $450K → $2.58M
Same upfront cash + each year's (own − rent) surplus invested in S&P 500 at actual annual returns. Median renter contributed $325K total.
Median wealth delta: $535K in favor of RENT + INVEST

Educational tool, not investment or real-estate advice. Past performance does not guarantee future results. Backtests use actual annual total returns including dividends from S&P 500 (Damodaran (NYU Stern) annual total return (with dividends), 1957-present.).

Buyer model: 30-yr fixed mortgage, P&I + property tax + insurance + maintenance (1% of value/yr) + HOA. Selling cost = 6%. Investor model: down payment + annual cashflow surplus invested in the chosen index at that calendar year's actual return.

Tax model: pre-tax comparison. Toggle "after-tax mode" to apply MID, SALT, LTCG, and the Sec 121 capital-gains exclusion.

This calculator does not adjust for: PMI (assumed 20%+ down), differential transaction costs by state, lifestyle factors (commute, schools, kids), illiquidity / forced-sale risk, or insurance availability constraints (e.g., FL/CA wildfire). Consult a fiduciary advisor and tax professional before acting on any of this.

State-grain HPI YoY + drawdown from peak is the cleanest free price-stress proxy. The national delinquency rate gives the macro mortgage-stress backdrop. True county-level mortgage delinquency lives in paid datasets (MBA NDS, CoreLogic LP).

Every lender above a size threshold has to report each application and what they did with it. The denial rate here counts only applications a lender actually ruled on — approved or denied. Files the applicant withdrew, and files closed as incomplete, are left out of both halves, so this runs higher than tables that bury them in the denominator. Compare every state and county →

Median Household Income

Census ACS B19013

Historically affordable markets sit at 3–4× income; over 5× is stretched, over 6× is severely overvalued. Lower ratios point to bargain opportunities.

When boomer-owner share is high, expect more inventory hitting the market over the next decade as homes transition. High vacancy + high old-stock often signals deferred-maintenance markets where buyers can negotiate.

  2. St. Lucie, Florida — 1,048 returns
  3. Broward, Florida — 271 returns
  4. Miami-Dade, Florida — 131 returns
  5. Suffolk, New York — 116 returns

Top 5 Destinations (where movers went)

  1. St. Lucie, Florida — 1,293 returns
  2. Palm Beach, Florida — 714 returns
  3. Indian River, Florida — 112 returns
  4. Brevard, Florida — 107 returns
  5. Broward, Florida — 101 returns

IRS Statistics of Income tracks county-to-county migration via tax-return change-of-address. Net migration uses the exemption count (a proxy for people, including dependents). True net flow can lag by 1–2 years vs. real-time movements.

Who's Moving In (Census ACS)

Source: Census ACS B07001 (5-year)
Inbound Movers (1 yr)
10,145
6.37% of pop. — moved here from outside the county
From Other States
4,056
2.55% of pop. — interstate inbound
From Abroad
984
moved into the county from outside the U.S.
Same House 1 Year Ago
90%
stable residents

Census ACS asks where people lived 1 year ago, so this counts inbound movers but does not show outbound — true net migration would require IRS SOI parsing.
