The Supply Picture In San Marcos

Median gross rent in San Marcos, TX is $1,322 a month, up 24.2% from $1,064 in the 2015–2019 survey (U.S. Census ACS 2020–2024). It's a healthy increase, without the spike some fast-growing metros saw.

Rental vacancy is 4.9%, within the normal range for a balanced market. Census vacancy estimates for smaller places carry wide margins of error, so we check them against current local listings. 66.5% of renters spend 30% or more of their income on housing. That limits how hard rents can be pushed, so renewals and retention matter more than big increases.

About 46.7% of homes in San Marcos are in buildings with 5 or more units, roughly 14,173 homes. That count rose 27.7% over five years, a sign of meaningful new apartment construction that newer buildings will compete with. The median home was built in 2001, so the housing stock is relatively new. Value-add plans here lean more on management and amenities than on heavy renovation. For comparison, HUD's fiscal year 2027 Fair Market Rent for a two-bedroom unit in the Austin-Round Rock-San Marcos, TX MSA is $1,817 a month.

Where San Marcos Stands Among Its Peers

Among the 133 Texas cities we track, San Marcos ranks 83rd for median gross rent, 1st for renter share and 103rd for five-year rent growth. Its rents fall in the middle of the pack.

Growth in renter households and new apartment homes has been roughly in balance.

San Marcos And Nearby Markets Side By Side

San Marcos's median gross rent of $1,322 is below the Texas median of $1,403, and its renter share is 69.2% compared with 37.4% statewide.

San Marcos Rent Affordability In Dollars

The median rent in San Marcos works out to $15,864 a year, about 30.9% of the median household income of $51,281. Under the common 30% guideline, a household needs about $52,900 a year to cover that rent comfortably. That's a heavier load than the Texas average of 21.5%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

Since the 2015–2019 survey, the median rent rose $258 a month ($3,096 a year), while median household income rose $10,902 a year. The two have moved together, so affordability today looks much like it did five years ago. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $1,817, is 37.4% above the median gross rent for all unit sizes. That gap matters for buildings that accept Housing Choice Vouchers, since local housing authorities base voucher payment standards on it.

What We Look For In A San Marcos Apartment Building

In San Marcos we focus on apartment buildings with 5 or more units. Some are stabilized and well run. Others have below-market rents or deferred maintenance that a better operator can fix. Either way, the deal has to make sense on current numbers.

Texas has no state income tax on wages, and property taxes are often one of the largest expenses for apartment owners. We estimate the tax bill as it will be after the purchase, because a sale can trigger a reassessment in many places. Texas has no statewide rent control law, though local rules on notices, fees and deposits still apply. Insurance quotes in Texas reflect hurricane and flood exposure and hail and wind damage, so we get a quote before we make an offer.

We use modest rent growth assumptions, realistic repair budgets and financing that can carry the property through a slower year.

Evaluating Apartment Syndications In San Marcos

Before you invest in an apartment syndication in San Marcos, with us or anyone else, the local data points to a few questions worth asking.

• What vacancy does the plan assume? Rental vacancy in San Marcos is 4.9%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 24.2% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• How big is the repair reserve? The median home in San Marcos was built in 2001, and even newer buildings need money set aside for roofs, HVAC and appliances.
• How will the building compete with new supply? Homes in 5+ unit buildings in San Marcos rose 27.7% over five years, so newer properties are part of the competition.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In A San Marcos Apartment Syndication Works

A syndication splits the work from the capital. As general partner, Skyline sources and buys the building, sets the business plan and runs it with a property manager. Limited partners invest money, own part of the property and receive reports, but they don't manage anything day to day.

It's a long-term commitment. The property has to be refinanced or sold before most capital comes back, and the outcome isn't certain. Eligibility rules vary by offering, and most are limited to accredited investors. See investing with Skyline Capital for how we work with limited partners.
