Do two methods point the same way?

Zillow estimates a current home value. FHFA tracks repeat mortgage transactions. Their growth rates should be read side by side, not averaged.

Resident income

How local income has compounded

BEA per-capita personal income divides all personal income by the county population. It is broader than wages, but it is not household income or a measure of what renters can afford.

Renter affordability

Who carries the heaviest rent burden

HUD CHAS separates renter households by income relative to local HAMFI. Moderate burden means housing costs above 30% through 50% of income; severe burden means more than 50%.

County brief

What the local evidence says

01Decision frame

Mercer County offers a credible gross-rent screen but a conflicted underwriting case. Zillow’s median home value is $453,317 and its median asking rent is $2,622 per month, implying a 6.94% gross yield before costs. This merits property-level investigation; leveraged or resale-dependent buyers should be cautious. Zillow’s -0.13% change is labeled 2026-06. FHFA’s repeat-transaction HPI reports +5.72% for 2025 and +67.53% cumulatively over five years, not annualized. It is an appreciation index, not a home value; the vintages and methods differ, so these measures should not be averaged.

02Housing economics

Keep market rent separate from HUD: the two-bedroom FMR is $1,950, a payment standard rather than an asking-rent estimate. The gross yield is therefore pre-expense. Carrying costs are central: the effective property-tax rate is 2.36%. Insurance, vacancy, repairs, management, financing, capital expenditures, and unit-level lease terms are not published, preventing a net-yield or property-specific cash-flow conclusion. Price is nearly flat while asking rent rose, but that does not establish durable rent growth.

03Demand & competition

Realtor.com provides MLS listing evidence, not closed-sale evidence. Active listings rose 16.04% to 698; listing prices softened and marketing times lengthened. That shows visible supply, not buyer demand alone. Net migration was -1,739, with a -$7,553 average AGI gap because incoming movers reported less than outgoing movers. QCEW covered county jobs fell 1.08% while average weekly wage rose 4.31%. Education and health services is the largest disclosed private supersector; QCEW is workplace, not resident, employment or the full economy. The mix warrants tenant-demand diligence, not a metro assumption.

04Risk & next checks

Inland flood is the dominant hazard; the modeled climate loss ratio is 0.18% of building value per year. That is not a property-specific insurance quote or repair budget, so obtain flood-zone, elevation, claims, drainage, mitigation, and address-level hazard evidence. Investor purchases are a minority of total purchases, with a 14.98% share; the record does not show investor returns or dominance. Verify achieved rents, concessions, closed-sale comparables, parcel taxes, insurance, lease-up, turnover, and financing. Until then, the gross screen cannot become a net-return or resale thesis.

WHAT THE LOCAL DISTRIBUTION SAYS

Mercer County's selected direct-evidence ZIP set presents a wide rent spectrum, so the operative question is whether a lease budget can meet current asking-rent conditions in a chosen ZIP rather than a single countywide figure. Zillow ZORI for the county is $2,622. Across the 12 shown ZIPs, ZORI ranges from $1,845 to $3,551, producing a $1,706 spread and a $2,284.50 median. The low end is associated with ZIP 08610 and the high end with ZIP 08550. Treat ZORI as a typical observed asking-rent index, not a quote for a particular unit: its breadth makes current listing-level verification more important than applying the county figure to every ZIP.

Zillow, ACS, and HUD answer different questions and should be read side by side, not combined into a common rent. Zillow ZORI is the typical observed asking-rent index. ACS supplies a multiyear survey estimate of median gross rent, whereas HUD FMR is an administrative bedroom-specific standard rather than asking rent. For example, ZIP 08618 has ZORI of $2,115, ACS median gross rent of $1,102, and a HUD FMR standard of $1,950; the packet's ZORI-to-HUD comparison is 108.5%. At the selected ratio endpoints, ZIP 08628 is at 95.3% of its HUD standard and ZIP 08550 at 182.1%. These contrasts are benchmarks for separate screening questions, not a conversion between survey rents, current asks, and program standards.

Burden and vacancy add distinct, descriptive ACS signals to the asking-rent evidence. At county level, 50.1% of renter households report paying 30% or more of income toward rent, while the vacancy rate is 4.7%. In the corresponding ZCTAs, ZIP 08611 pairs a 61.9% burden share with 4.6% vacancy, while ZIP 08550 reports 15.5% burden and 1.6% vacancy. ZIP 08638 has the selected set's 10.0% vacancy high. These are not causal findings or a measure of listings available today: vacancy reflects survey housing status and burden reflects household finances. The practical trade-off is to examine current unit availability separately from whether a prospective household has adequate rent-income margin.

Coverage and geography constrain all ZIP comparisons. The direct-evidence selection is not an exhaustive county inventory. It covers 47,798 renter households but uses ZIP/ZCTA matches; Census ZCTAs are statistical areas, not USPS delivery ZIPs. ZIPs are displayed in Mercer County when it has the largest HUD residential-address share, yet cross-county shares matter: the selected range falls to 74.4%. Thus these results should guide a short list, not establish ZIP-wide conditions. For any property, check the advertised monthly rent, unit type and bedroom count, lease term, utilities and mandatory fees, availability, address-to-ZIP/county assignment, and eligibility or income rules against the intended use of the HUD standard.

READ BEFORE USING

ACS county and ZCTA statistics are five-year survey estimates, and ZCTAs are Census statistical areas rather than USPS delivery ZIPs. They should not be read as current listing conditions, unit-level results, or exact boundaries for every delivery ZIP.

ZIPs may cross county lines; this packet displays a ZIP in Mercer County based on its largest HUD residential-address share. The selected direct-evidence set is not exhaustive, so its rent, burden, and vacancy range does not represent every county ZIP or property.

Bear case

What can break the county thesis

  1. Property-specific flood exposure, insurance terms, and mitigation costs may make the modeled county loss ratio unsuitable for the asset.
  2. Taxes and unprovided operating, financing, vacancy, and capital costs may erase the gross-yield screen.
  3. Out-migration, covered-job contraction, and softer visible listings may weaken tenant-demand or resale assumptions.
Underwriting questions

Before pricing a property

Is the rent figure HUD FMR or market rent?

It is the published median monthly asking market rent. HUD FMR is a separate two-bedroom payment standard and should not be used as a market-rent estimate.

What does the FHFA measure establish?

It is a repeat-transaction appreciation index for a different supplied vintage from Zillow, not a dollar home value. Its result should not be merged with Zillow into one growth rate.

Does the investor share prove strong investor demand?

No. It measures non-occupant purchase mortgages as a share of total purchase mortgages; the record does not establish investor returns, future competition, or buyer demand.
