First look at the property

This is a single-family home in Los Fresnos, Cameron County, with an appraised value of $123,000 CCAD-CA and about 1,264 sq ft of living area. Below is a short read of what speaks for and against it, based on the data on this page.

Strengths

  • 5 bedrooms and 2 bathrooms suit families and many tenants.
  • Appraised value and building facts come from the CCAD-CA county record, not from a model.
  • Plumbing / electrical risk looks low on the available data.
  • Modeled cash flow is positive in the base case ($30 per month).

Weaknesses

  • Property tax of about $2,340 per year ($195 per month) is a large running cost.
  • HOA dues, special assessments and title issues are not known and must be checked.

Working hypothesis: this looks like a candidate worth a closer look for rental income. That is a starting point, not a conclusion; the sections below show the numbers behind it.

Methodology (TX-model v1.1 · 2026-10-12): the estimate is the county appraisal district’s market value for this property, shown with a range and cross-checked against nearby comparable values. when no county record is used, estimated living area × a city-level price per sq ft × age factor × a property-level seeded variation, cross-checked against size- and age-adjusted nearby comparable values. Sale prices, listings and assessments from county records are not connected, so every number on this page that is not marked “OSM” is a modeled estimate [P].

True cost of ownership

Your assumptions

An automated estimate is not an appraisal, inspection, insurance quote or lender approval. Actual loan terms depend on the borrower.

Listing

Property tax scenarios

Model what a buyer may pay, separately for an owner-occupant with a homestead exemption and for an investor. The current owner’s modeled bill is shown for contrast.

Assumptions

Rules used: homestead exemption applies to the school-district part of the rate for a qualifying primary residence; homestead appraisal growth is capped at 10% per year after the first year; non-homestead property may have a separate cap (verify current law and your county). The exemption does not apply automatically to investment property. Verify rates, exemptions and caps with the county appraisal district and the Texas Comptroller.

Property tax protest support

  • Deadline: generally May 15 or 30 days after the notice of appraised value is mailed, whichever is later – confirm the date on your notice.
  • Check the appraisal district’s record of your property (area, year built, condition, exemptions) for errors.
  • Gather evidence: comparable assessments and sales, photos of defects, repair estimates.
  • Compare your assessed value per sq ft with similar nearby homes (this property’s modeled value: $97 per sq ft).
  • A protest does not guarantee a reduction.

Quote checklist

  • Ask for the CLUE report of the property and seller’s claims history.
  • Get quotes from at least three insurers/agents, with the same coverage and deductibles.
  • Confirm roof age/material, and whether hail damage is excluded or cosmetic-only.
  • Ask about wind/hail and named-storm deductibles.
  • Check flood zone on the FEMA Flood Map Service Center and get a flood quote.
  • Confirm whether the Texas FAIR Plan / TWIA applies (coastal areas).

Formulas
  • Gross rental yield = annual scheduled rent ÷ price.
  • NOI = effective gross income − operating expenses (no debt service, no income tax).
  • Cap rate = NOI ÷ price.
  • Cash flow = NOI − debt service − capex reserve.
  • Cash-on-cash = annual pre-tax cash flow ÷ cash invested (down payment + closing + repairs + reserves + points/fees).
  • DSCR = NOI ÷ annual debt service.
  • Break-even occupancy = (operating costs + debt service + reserve) ÷ potential gross income.
  • IRR from the initial cash, yearly cash flows with growth, and net sale proceeds after selling costs and loan payoff.
  • Equity buildup shows principal paydown and appreciation separately.

Overall assessment

Our assessmentPromising on paper, verify rent and costs first

As a home for your own use

Estimated cost of owning is about $1,023 per month with 20% down at 6.75%, including property tax, insurance, HOA and maintenance. Because of the building age, an independent inspection is the first step. Compare the price with recent sales of similar homes in Los Fresnos before you decide.

As a leveraged rental

Base case gross yield is 12.2 %, cap rate 6.5 % and cash flow $30 per month with 25% down. The property covers its costs in the base case, but the margin depends on rent, vacancy and insurance holding up. Change any assumption in the financial model above to test it.

Largest open questions

  • The real market value: confirm with sold comparables and, if buying, an appraisal.
  • The tax level after purchase: homestead exemptions and reassessment change the bill.
  • The insurance quote: hail, wind and flood cover can differ a lot between addresses.
  • Technical condition: foundation, roof and HVAC need a physical inspection.

Method and limits: this is a desk analysis from public records, map data and stated assumptions. Items marked [P] are probability-based estimates. It is not an appraisal, inspection or legal advice.

Who should confirm what

  • Inspection: condition, roof, HVAC, foundation, plumbing
  • Insurance quote: wind/hail premium and availability
  • Official records: appraisal district, county clerk, permits
  • Professional review: title, survey, HOA documents, tax advice

Official sources

Texas Department of Insurance · Comptroller property tax · HOA portal · FEMA flood maps · Appraisal district · County clerk · Permits · GIS

Confirmed facts = address, location and OSM-mapped building data · [P] = modeled estimate · everything else is an unresolved question.
