Due Diligence Questions for Buying a Houston Rental Property
Buying a rental property means buying the building, the tenants, the leases and every problem that comes with them. Due diligence is the window to find out what you're really getting. In Houston, that means asking hard questions about foundations, flooding, aging systems, permits and the existing rent roll before the deal is final.
This guide lists the due diligence questions a builder would want answered before an investor buys a Houston rental home or small multifamily property. It focuses on the physical property and the practical side of operating it.

Questions about the building
- What does the foundation look like? Look for cracks, slopes, sticking doors and prior repairs. Ask for repair records and any transferable warranties. Our guide to signs of foundation problems in a Houston home explains what to look for.
- How old is the roof, and has it leaked? Ask for repair and insurance claim history. Our guide to signs your roof needs replacement helps assess it.
- What are the supply and drain pipes made of? Galvanized, polybutylene, cast iron and clay lines may need replacement. Our guide to plumbing issues common in older Houston rentals covers what to watch for.
- Has the sewer line been camera-inspected? If not, consider doing it.
- What is the electrical panel and service? Outdated panels or wiring can affect insurance and safety.
- How old are the HVAC systems and water heaters?
- Is there any sign of water damage or mold?
- Was the property built before 1978? If so, lead paint rules may apply to future repairs. See the EPA's lead disclosure rules and renovation rules.
Questions about flooding and drainage
- Is the property in a mapped flood zone? Check the FEMA Flood Map Service Center.
- Has it flooded before? Review the seller's disclosure and ask directly. Texas disclosure forms are available through TREC.
- What does flood insurance look like? FloodSmart explains the National Flood Insurance Program.
- Does the lot drain well? Watch for standing water, poor grading and downspouts discharging at the foundation.
- Are there drainage projects nearby? The Harris County Flood Control District has project information.
Questions about permits and compliance
- Were additions, garage conversions and major systems work permitted? Our guide to buying a property with unpermitted work explains the risks.
- Are there open code violations?
- Do deed restrictions or HOA rules limit rentals, additions or uses? Review them with your attorney.
- For small multifamily, does the property have the approvals needed for the number of units?
- Do smoke alarms, security devices and other required items meet Texas requirements? Texas Property Code Chapter 92 addresses several landlord requirements. Review compliance with your attorney.
Questions about tenants and leases
- Who lives there now, and under what leases? Get copies of all leases and amendments.
- When do leases end?
- Are security deposits accounted for, and how will they transfer?
- Are any tenants behind, or in a dispute with the current owner?
- What maintenance requests are open?
- Have tenants been told about any planned changes?
Tenant and lease questions carry legal consequences. Your attorney should review the leases, estoppel certificates if used and the transfer of deposits. Our guide to selling a rental property with tenants explains the seller's side.
Questions about operating the property
- What have utilities, repairs and maintenance looked like? Ask for records, not summaries.
- Who pays which utilities, and are units separately metered?
- Who has been managing the property, and will records transfer?
- What vendors have serviced the property?
- Are there service contracts that would transfer?
Questions about taxes and insurance
- What are the current property taxes, and could they change after the sale? Check the Harris County Appraisal District or the appraisal district for the county.
- What will insurance cost and cover? Roof age, wiring, plumbing and flood exposure all affect coverage. The Texas Department of Insurance has consumer resources.
- Are there past insurance claims on the property?
Your tax advisor and insurance professional should weigh in on these items.
Questions about the renovation plan
If you plan to improve the property:
- What work is needed now versus later?
- Can units be renovated while occupied, or only at turnover?
- Which items need permits?
- Does the floodplain status affect how much renovation is allowed without added requirements? See our guide to floodplain renovation rules for investors.
- Has a builder walked the property and written a scope?
Our guides to investor renovation scope and bidding and to rental unit refresh vs full renovation help build the plan, and our guide to duplex and fourplex renovation covers small multifamily.
Getting the right people involved
- Attorney: Contract, title, leases, deed restrictions and compliance.
- Inspector and builder: Physical condition and renovation scope.
- Specialists: Foundation engineer, plumber with a sewer camera, electrician and roofer as needed.

- Agent or broker: Market and rent comparisons.
Common mistakes to avoid

- Assuming past work was permitted.
- Not reviewing leases and deposits with an attorney.
- No builder walk-through before planning renovations.
