Sanilac (MI) Investor Pulse Report (2026-Q1)

In Sanilac County, MI, investors hold a significant 23.5% of the Single-Family Residential (SFR) market, totaling 4,032 properties out of 17,148.

Individual investors are the overwhelming force, owning 3,390 properties, which accounts for 84.1% of the entire investor portfolio. In contrast, companies own just 671 properties, or 16.6%.

The number of individual landlord entities (4,625) compared to the properties they own (3,390) suggests a high degree of co-ownership or smaller, fragmented portfolios are common in the area.

Cash is king in Sanilac County's real estate investing scene. A staggering 3,702 investor-owned properties were acquired with cash, while only 330 are currently financed, indicating a low reliance on leverage among local investors.

The portfolio is heavily geared towards rentals, with 3,957 properties classified as rented, confirming that the primary strategy for these owners is generating rental income.

In a striking reversal of national trends, landlords in Sanilac County consistently pay more for properties than traditional homeowners. In Q1 2026, investors paid an average of $211,500, which is $16,005 or 8.2% higher than the homeowner average of $195,495.

This premium has been a persistent market feature. In Q3 2025, the gap was an 11.1% premium ($246,986 vs. $222,224), and in Q1 2025, it peaked at a remarkable 31.9% premium ($296,586 vs. $224,872).

The lack of an investor discount suggests a highly competitive market for certain types of properties, where investors may be targeting homes with specific features not captured in general price averages or are simply willing to pay more to secure assets.

While acquisition prices for investors have fluctuated quarterly, the overall trend from 2024 ($217,268) to 2025 ($235,707) shows a general upward trajectory in what investors are willing to pay.

The data does not contain any purchases for the most recent timeframes, indicating either a lag in reporting or a slowdown in transaction velocity for this specific segment.

Investor activity accounted for 17.9% of all SFR sales in the last quarter, with landlords acquiring 5 of the 28 total properties sold in Sanilac County.

The purchasing activity was exclusively driven by small-scale investors. Mom-and-pop landlords (Tiers 01-04) made up 100% of these acquisitions, with institutional investors (Tier 09) showing no buying activity at all.

New market entrants are a key driver of activity, as single-property landlords (Tier 01) acquired 3 properties, representing 60% of all investor purchases for the quarter.

The remaining 40% of investor purchases were made by landlords in the 3-5 property tier, who acquired 2 properties.

This quarter's activity reinforces the market's structure, where growth comes from new and small existing landlords rather than large-scale portfolio aggregation.

The investor landscape in Sanilac County is overwhelmingly dominated by small-scale owners. Mom-and-pop landlords, defined as those owning 1-10 properties, control a massive 97.6% of all investor-held SFRs.

Single-property landlords are the bedrock of the market, with 3,492 properties making up 84.8% of the total investor portfolio. This highlights a market characterized by a large number of individuals with one rental property.

In stark contrast, institutional investors with 1,000 or more properties have a minimal footprint, owning just 4 properties, which equates to only 0.1% of the investor-owned housing stock.

Mid-size landlords (11-1,000 properties) also represent a very small fraction of the market, collectively owning just 2.3% of the properties.

This distribution demonstrates a highly decentralized ownership structure, challenging any narrative of large corporate landlords controlling the local rental market.

Individual investors form the foundation of ownership in Sanilac County across smaller portfolio sizes. They own 87.6% of single-property investments (3,080 properties) and 79.6% of two-property portfolios (176 properties).

The transition toward a corporate structure becomes apparent as portfolio sizes increase. The 6-10 property tier marks the crossover point, where ownership is evenly split, with both individuals and companies holding 33 properties each (50.0%).

Even in the 3-5 property tier, individuals maintain a strong majority, owning 182 properties (76.2%) compared to the 57 properties (23.8%) owned by companies.

This pattern suggests that as local investors scale their operations beyond five properties, they are more likely to incorporate for liability and financial reasons.

The data clearly shows that the path to building a larger rental portfolio in this market often involves a shift from personal ownership to a more formal company structure.

Investor ownership in Sanilac County is not evenly distributed; it is highly concentrated in specific areas. The zip code 48450 is the clear hotspot, containing 1,358 investor-owned properties, which alone represents over a third of the county's entire investor portfolio.

Following 48450, other key areas for investors include 48427 (389 properties), 48469 (307 properties), and 48419 (306 properties), demonstrating a clear geographic focus for investment capital.

Analysis of ownership rates reveals pockets of intense investor saturation. The 48410 zip code leads with a 66.7% investor ownership rate, followed by 48441 (57.6%) and 48434 (56.5%), although these areas have smaller total property counts.

This distinction between high-count and high-percentage regions is important. While 48450 has the most units, smaller zip codes like 48410 represent markets where investors are the dominant property owners.

These geographic patterns provide a map of where investment activity is most prevalent, highlighting specific communities where rental properties make up a substantial portion of the housing stock.

Investors in Sanilac County are in a clear accumulation phase, consistently buying far more properties than they sell. In 2025, landlords were strong net buyers, with 176 acquisitions against only 12 dispositions.

This aggressive buying pattern is a continuation of previous years. In 2024, the net acquisition was even larger, with 240 properties purchased and only 28 sold by landlords.

The transactional data for institutional investors (1,000+ properties) tells a different story. Their activity is minimal and inconsistent. In 2025, they were marginal net buyers (3 buys vs. 1 sell), but in 2024 they were net sellers (1 buy vs. 2 sells).

The vast majority of market momentum is driven by the smaller, mom-and-pop segment, which continues to expand its holdings in the county.

The low sales volume from the existing landlord pool indicates a long-term hold strategy is prevalent, with few investors choosing to exit their positions in the current market.

In the first quarter of 2026, landlords were involved in 17.2% of all SFR transactions, purchasing 5 of the 29 homes sold in Sanilac County.

Activity was entirely concentrated among smaller investors. Landlords in the single-property (Tier 01) and 3-5 property (Tier 03) tiers were the only active buyers, with zero transactions recorded for institutional or even mid-size investors.

A notable pricing difference emerged between the active tiers. First-time or single-property landlords paid an average of $154,167, while more established small landlords (3-5 properties) paid a much higher average of $297,500, indicating different acquisition strategies or target property types.

The market for investor acquisitions appears to be sourced entirely from traditional sellers, as 0% of landlord purchases were from other landlords. This shows investors are adding to the overall rental stock rather than trading existing rental properties among themselves.

The transactional data from this quarter reaffirms the broader market structure: a market driven by new and small investors who are expanding their portfolios by purchasing from homeowners.
