Why so many small Texas buildings are master-metered
Many older Texas apartment buildings were built with a single water meter for the whole property, and some with a single electric or gas meter. Re-plumbing or rewiring to give every unit its own meter is expensive, so a lot of 5-10 unit buildings still run that way. Water and sewer are the most common owner-paid utilities; trash service is also usually paid by the owner.
How owner-paid utilities affect DSCR
If you pay the utilities, the cost is an operating expense. On programs that measure coverage on net operating income, every dollar of utility expense reduces NOI and coverage. On programs that compare gross rent with the monthly payment, utilities may not enter the ratio directly, but the lender still reviews them when judging the building.
Illustration with user-style numbers: a 6-unit building with owner-paid water, sewer and trash spends $550 a month on those services. That is $6,600 a year off NOI. If annual principal and interest is $50,000, that one expense line moves NOI-based coverage by about 0.13.
Three ways owners handle utilities
- Owner pays, rent includes it. Simple, and common in older buildings. Rent may be a bit higher to compensate, but the expense is fully on you.
- Submetering. A meter on each unit measures actual use, and the owner bills each tenant for their share.
- Allocation. Without unit meters, the owner divides the master bill among units using a formula, such as by occupants or square footage, and bills each tenant.
Texas rules on submetering and allocation
Texas regulates how apartment owners submeter or allocate water and sewer costs to tenants. The Public Utility Commission of Texas oversees those rules, which cover things such as what must be disclosed in the lease, what formulas are allowed, what can be charged, and how bills must be presented. Electric submetering has its own rules. If the building bills tenants back, ask the seller for the method used, the lease language and a sample tenant bill, and confirm the practice follows current rules. Penalties for non-compliance, or tenants disputing improper charges, can wipe out the reimbursement income you were counting on.
This is not legal advice; check the current rules with the Public Utility Commission of Texas or a Texas real estate attorney.
How lenders treat reimbursements
Lenders generally credit utility reimbursements as income only when they are:
- Written into the leases
- Collected consistently, as shown in bank deposits or the T-12
- Billed under a compliant method
If reimbursements are new, inconsistent or undocumented, expect the lender to count the full utility expense and little or none of the reimbursement. If you plan to start billing back after you buy, the lender will usually size the loan on the current setup.
Due diligence checklist
- Get 12 months of utility bills for every owner-paid service.
- Note which units have their own meters and for which utilities.
- Ask how bill-backs are calculated and see the lease language.
- Check whether any leak, high usage or billing dispute is driving costs.
- Look at fixtures: older toilets and plumbing can raise water use.
- Put the real annual cost in the "other monthly operating costs" field of the 5-10 unit DSCR calculator.
Is converting to separate meters worth it?
Sometimes. Separate meters can shift usage costs to tenants and encourage conservation, but the work can be expensive and disruptive, and it changes what tenants pay overall, which can affect rents and turnover. If you plan a conversion as part of a value-add plan, budget it with the renovation and consider bridge-to-DSCR financing until the new setup is in place and documented.
Common utility questions on a purchase
Buyers often ask whether they can simply raise rents to cover owner-paid utilities. Sometimes, at renewal, if the market supports it, but the lender will size the loan on the rents in place at closing. Others ask whether a building with a high water bill has a leak. Sometimes it does, and fixing it is one of the cheapest ways to improve net operating income. Compare usage month to month in the bills; sudden jumps usually point to a problem rather than tenant behavior.
Finally, check who pays for common-area electricity, exterior lighting, laundry machines and any pool or irrigation. Those costs are usually the owner's even in individually metered buildings, and they belong in the T-12.
Questions investors ask
Do lenders treat owner-paid utilities as an expense?
Yes. Owner-paid utilities reduce net operating income, which matters most on programs that measure coverage on NOI.
Can I count utility bill-backs as income?
Often, if they are in the leases, collected consistently and billed under a compliant method. Lenders may discount new or undocumented reimbursements.
