Houston property facts, verified against HCAD and MLS — not modeled around them.
OfferQS is decision-support software for Harris County real estate: rental investors, flippers, homebuyers, owners and the agents who represent them. Every number on this site carries where it came from and when it was last seen. Unknown is shown as unknown, never as zero.
Three public-record facts, before you sign in
- The current HCAD appraised and market value, and whether an exemption is on file.
- Every taxing jurisdiction on the account — school, county, city, MUD/PID — with its adopted rate.
- The FEMA flood zone, when it has been mapped for this property.
No competitor combines these on one page. Zillow and Redfin show a modeled estimate; HAR.com shows the as-listed tax line. This is the appraisal district itself, verified against HCAD and MLS — not modeled around them.
Who OfferQS is for
Rental investor / small landlord
You buy 1–10 rental units in Harris County and are stuck on the local truth spreadsheets can't give you: real rent, taxes, insurance and MUD.
Buyer-side agent
You need a client-safe analysis you would not be embarrassed by, in minutes, with facts beside the listing and sources attached.
First-time investor
This is your first rental purchase and you need every number explained, with conservative defaults, not just a spreadsheet that assumes you already know the rules.
House flipper
You run a handful of projects a year and get hurt by an inflated ARV, an underestimated rehab budget, or a holding-cost timeline with no buffer.
Owner / landlord operations
You already own Houston rentals and need to decide a renewal, a rent increase, or a protest — on your own property, not a market search.
Homebuyer and family
You are buying where you will live and have been burned by hidden monthly costs — HOA, MUD, insurance — that never showed up on the listing.
Listing agent and owner-seller
You are pricing or taking a listing and need net proceeds first, a defensible comp range second — never a single invented "value."
Pricing
$34.99/month or $349/year per named user — about $29.08/month paid annually, 16.9% less.
