THE PROPERTY

Get to know the property.

Welcome to 301 Armstrong, a well-maintained 3-bedroom, 2-bath home offering a little extra breathing room in the heart of San Marcos. With no neighbor directly behind the home and no neighbor on one side, the setting offers an added sense of separation and privacy that can be hard to find this close to town.

Inside, the open floor plan makes great use of the space, creating an easy flow between the living, dining, and kitchen areas—perfect for everyday living or spending time with friends. New flooring was installed throughout the home in August 2025, and the interior has recently been refreshed with new paint, repaired baseboards, recaulked finishes, and new blinds throughout. The primary bedroom features its own private half bath and walk-in closet, while two additional bedrooms offer flexibility for guests, a home office, hobbies, or whatever fits your lifestyle.

One of the home’s standout upgrades is the LifeSource whole-home water filtration system, providing filtered water throughout the house without the hassle of individual filters. The home has clearly been cared for, making it an inviting option for someone looking for a comfortable home that feels fresh and ready to enjoy.

Out back, the privacy-fenced yard creates a comfortable space for morning coffee, pets, outdoor dining, or relaxing at the end of the day. With fewer adjoining homes around the property, the backyard enjoys an added sense of privacy while still being close to everything San Marcos has to offer.

And when you’re ready to head out, you’re just minutes from downtown, Texas State University, the San Marcos River, local restaurants, shopping, and easy access to I-35. 301 Armstrong offers a comfortable home base with added privacy, thoughtful updates, and an easy San Marcos lifestyle.

OWNERSHIP, WITH A PLAN

Explore this property’s rental potential with an all-cash purchase. Monthly rent starts at 5% of the purchase price per year, divided by 12. Adjust it and the other assumptions to explore your scenario.

These are planning assumptions, not a rental appraisal or a loan quote. The starting rent is a price-based estimate; a local leasing professional can help confirm market rent.

Investor outlook assumes an all-cash purchase. No mortgage payment is deducted.

Estimated monthly cash flow · cash purchase$414.45
Estimated monthly rent$1,100.00
Cap rate2.13%

Annual operating income: $5,633.41

HOA: No HOA cost is included because the listing source does not report one. Confirm whether HOA dues apply before relying on this estimate.

Purchase price
Rental income & operating costs

Purchase price × 5% ÷ 12. Updates with purchase price until you enter a custom rent.

Annual insurance starts at purchase price × 0.25%, rounded to the nearest available amount. Updates with purchase price until you choose another amount.A planning estimate, not an insurance quote. Adjust it for your property and coverage.

Percentages are editable examples, not ERA fee quotes. Management is applied to rent after vacancy; maintenance and capital reserves use scheduled rent. Add owner-paid utilities, mortgage insurance and other recurring expenses under other costs.

How this scenario is calculated

Annual operating income is rent after vacancy, management, maintenance, taxes, insurance, HOA and other operating costs, before financing and capital reserves. Cap rate divides annual operating income by purchase price. Estimated monthly cash flow assumes an all-cash purchase: rent after vacancy, management, maintenance, taxes, insurance, HOA, other operating costs and capital reserves. No mortgage payment is deducted. The mortgage calculator is separate; loan payments would reduce cash flow for a financed purchase. One-time acquisition costs, renovations, income taxes, depreciation and appreciation are excluded.

Mortgage payment calculator

Explore financing separately. These loan settings do not change the all-cash investor outlook.

Mortgage assumptions

20% down and 7% interest are illustrative starting values.

Estimated monthly principal & interestLoan payment only. Excludes property taxes, homeowners/flood insurance, mortgage insurance and HOA dues.

About this payment estimate

Based on a fixed-rate, fully amortizing loan with monthly payments and the price, down payment, interest rate and term you select. The interest rate is an example, not a current rate offer or APR; APR includes certain loan costs. This is an illustration, not a Loan Estimate, approval, offer of credit or commitment to lend.

Your actual payment, rate and eligibility depend on your lender, credit, loan program and property. Closing costs, points, prepaid expenses and lender fees are not included. Taxes and insurance may change, and mortgage insurance may be required, particularly with a down payment below 20%. Ask your lender for a Loan Estimate and a complete monthly payment including applicable taxes, insurance and fees.

Dollar results are rounded to the nearest cent; calculations retain precision until display. A cash purchase has no loan payment but still has ownership costs. Understand your total home payment (CFPB).
