Sanilac (MI) Investor Pulse Report (2025-Q4)

Sanilac County's landlord-owned SFR portfolio totals 4,050 properties, representing a significant 23.6% of the total SFR market of 17,149 properties. This high penetration indicates a strong and established investor presence within the county.

Individual investors overwhelmingly dominate the market, holding 3,405 properties (84.1%) compared to companies with 675 properties (16.7%). This highlights the significant role of individual mom-and-pop landlords over corporate entities.

The composition of landlord entities further reinforces this, with 4,664 individual landlords versus only 545 company landlords. This disparity in entity count, coupled with property ownership, solidifies the individual investor as the foundational component of the local rental market.

A striking 3,729 (92.1%) of landlord-owned properties are held with cash, demonstrating a preference for unfinanced assets and potentially signaling a stronger financial position or long-term hold strategy. Only 321 properties (7.9%) are financed.

The nearly universal focus on rentals is evident, as 3,970 (98.0%) of landlord-owned properties are non-owner-occupied and rented. This confirms that investor activity in Sanilac County is primarily geared towards generating rental income.

In a notable divergence from national trends, Sanilac County landlords consistently paid a premium for SFR properties compared to traditional homeowners across 2025. In Q4 2025, landlords acquired properties at an average price of $270,008, which was $46,268 (20.7%) higher than the $223,740 paid by homeowners.

This landlord premium was not static, showing significant quarter-over-quarter fluctuations. It surged to its highest point in Q1 2025, with landlords paying $296,586, a substantial 34.4% premium over homeowners at $220,654.

While the premium narrowed to 5.2% in Q2 ($206,746 for landlords vs $196,475 for homeowners) and 7.8% in Q3 ($239,585 vs $222,244), it resurged to 20.7% in Q4. This fluctuating but consistently higher price paid by landlords indicates robust investor demand even at elevated costs.

The absence of recorded landlord acquisition counts for individual quarters in Section 6-1, despite price data being available in 6-2, suggests a nuanced data capture method; however, the average prices reliably indicate landlord spending patterns.

The price appreciation from previous years to the current quarter cannot be directly assessed from this section, as all landlord acquisition counts for the designated timeframes were recorded as zero, limiting direct trend analysis on acquisition velocity.

Landlords in Sanilac County accounted for 38 (27.5%) of the 138 total SFR purchases in Q4 2025, indicating a significant and active presence in the housing market. Non-landlord buyers made up the remaining 100 purchases.

Mom-and-pop landlords (Tiers 01-04) overwhelmingly drove this purchasing activity, acquiring 37 properties, representing 97.4% of all landlord purchases this quarter. This demonstrates the continued vitality of smaller-scale investors.

The single-property tier (Tier 01) was particularly active, responsible for 35 properties (92.1% of landlord purchases) across 48 distinct entities. This suggests a healthy inflow of new individual landlords entering the market, forming the backbone of Q4 acquisition.

In stark contrast, institutional investors (Tier 09) made no purchases in Q4 2025, underscoring their minimal role in recent acquisition trends within Sanilac County.

The average properties per entity for Q4 varied, with single-property entities acquiring 35 properties across 48 entities (0.73 properties/entity), suggesting that some entities were identified as active but may not have completed a distinct single-property purchase this quarter or represent partial ownership.

Mom-and-pop landlords (Tiers 01-04) exert overwhelming control over the investor-owned SFR market in Sanilac County, holding 97.6% of all such properties. This concentration highlights their critical role in the local rental housing ecosystem.

The single-property tier (Tier 01) forms the vast majority of this dominance, accounting for 3,501 properties or 84.8% of the total landlord-owned SFRs. This signifies that first-time and small-scale landlords are the predominant force.

In a sharp contrast to market narratives, institutional investors (Tier 09, 1000+ properties) hold a negligible share of just 0.1% of investor-owned SFR, equating to only 4 properties. This reinforces the local, non-institutional nature of Sanilac's landlord market.

Mid-size landlords (Tiers 05-08, 11-1000 properties) collectively own a small but present share, with a combined 2.3% (97 properties). This includes 44 properties in Tier 11-20, 40 in Tier 21-50, 3 in Tier 51-100, and 10 in Tier 101-1000, illustrating a steep drop-off in larger portfolios.

Data regarding acquisition prices by tier and specific entity counts per tier are not provided in this section, precluding direct analysis of pricing strategies or average portfolio growth across investor sizes.

Individual investors are the dominant force in the smaller tiers within Sanilac County. They hold 87.6% of single-property portfolios (Tier 01) with 3,089 properties and 80.3% of two-property portfolios (Tier 02) with 175 properties, significantly outpacing company ownership in these segments.

A clear crossover point occurs at the 6-10 property tier, where company ownership surpasses individual ownership for the first time. Companies own 52.3% (34 properties) in this tier, while individuals hold 47.7% (31 properties).

In the small landlord (3-5 properties) tier, individuals maintain a strong majority, owning 75.5% (185 properties) compared to companies at 24.5% (60 properties). This reinforces the individual-centric nature of most small-scale investing.

This pattern indicates that as portfolio size increases, the likelihood of company ownership grows. However, the data for tiers above 10 properties is not broken down by owner type in this section, limiting further analysis of this trend in larger portfolios.

No data is provided in this section to compare acquisition prices between individual and company buyers within each tier, nor is there information on growth patterns by owner type across different timeframes.

MI-Sanilac-48450 emerges as the primary hub for investor-owned properties in Sanilac County, housing 1,362 properties, which represents a substantial 39.2% of its total SFR market. This demonstrates a significant concentration of investor activity in this particular zip code.

Beyond absolute counts, several zip codes exhibit extremely high investor ownership rates, signaling deep market penetration. MI-Sanilac-48410 leads with an impressive 66.7% of its SFR properties being investor-owned, followed by MI-Sanilac-48441 at 57.6% and MI-Sanilac-48434 at 55.9%.

The dual appearance of MI-Sanilac-48450 in both the top 5 by count and top 5 by percentage indicates it is a large and highly penetrated market for investors. In contrast, other high-percentage regions like MI-Sanilac-48410 might represent smaller markets with a greater proportion of investor-owned homes.

The lowest investor ownership rate among the top-by-count regions is found in MI-Sanilac-48422, with 293 investor-owned properties comprising 13.1% of its market. This highlights the varied landscape of investor presence even within a single county.

While geographic distribution of properties and ownership rates are clearly defined, no data on average acquisition prices per sub-geography is provided in this section, limiting analysis on regional pricing strategies or market value disparities for investors.

Landlords in Sanilac County consistently operated as net buyers throughout 2025, culminating in a robust 7.29x buy-to-sell ratio in Q4 (51 buys versus 7 sells). This pattern signals a continued strategy of portfolio accumulation rather than divestment.

Across the entire year 2025, all landlords maintained a net buyer position, with 191 buys against 20 sells, resulting in a net increase of 171 properties. This consistent accumulation contrasts with 2024's activity of 243 buys and 28 sells, which also showed significant net buying.

Institutional investors (1000+ tier) presented a more nuanced transactional pattern. After being net sellers in 2024 (1 buy vs 2 sells), they shifted to being net buyers in 2025 overall, with 3 buys and 1 sell. This indicates a strategic shift towards accumulation by this small segment.

Q4 2025 saw a decrease in landlord buy volume from Q3 (51 buys vs 69 buys), while sell volume increased (7 sells vs 2 sells). This suggests a slight rebalancing in the market, though the net position remains strongly positive for buyers.

The absence of data for landlord-to-landlord transaction percentages and average buy/sell prices for these historical transactions prevents a deeper analysis of market liquidity and implied profit margins within this section.

Landlords were significant players in Sanilac County's Q4 2025 transaction market, accounting for 51 of the 202 total SFR transactions, representing a 25.2% market share. This consistent activity underscores their ongoing influence.

Q4 transaction volume was overwhelmingly driven by mom-and-pop landlords (Tiers 01-04), who accounted for 50 transactions, with the single-property tier alone making 48 transactions. This confirms that smaller investors are the primary engine of market liquidity.

Pricing analysis by tier reveals varying strategies: Single-property landlords (Tier 01) paid the highest average purchase price at $278,162. In contrast, small landlords (Tier 3-5) paid $137,500, and large landlords (Tier 101-1000) paid $168,100, indicating a potential inverse relationship between portfolio size and acquisition price in Q4.

Inter-landlord trading activity was notably low, with only 2 out of 48 Tier 01 transactions (4.2%) involving a buy from another landlord, and 0% for other active tiers. This suggests that most landlord acquisitions in Q4 were from non-landlord sellers.

Institutional investors (Tier 09) showed no transaction activity in Q4, mirroring their absence in Q4 purchase data from Section 7. Their average purchase price was recorded as $0 due to this lack of activity.
