Houston, explained
Short answers to the local things that confuse buyers and sellers. General information to help you ask the right questions.
What's a MUD?
A Municipal Utility District (MUD) is a local government district that pays for water, sewer and drainage, and sometimes parks or roads, often in newer neighborhoods.
Homeowners pay a MUD property tax, which adds to the home's total tax rate, and usually pay the MUD for water and sewer service too. MUD tax rates vary a lot, so ask for the rate when you look at a home.
What's a PID?
A Public Improvement District (PID) pays for things like roads, landscaping or amenities in some newer neighborhoods.
Owners pay a yearly assessment, often collected along with property taxes, and it can last for many years. Ask whether a home is in a PID and what the yearly amount is.
Why does Houston have no zoning?
The City of Houston has no traditional zoning. Instead, many neighborhoods have deed restrictions: rules recorded with the property that can limit what's built or how it's used.
They're often enforced by an HOA or civic club. It's worth reading them before you buy, especially if you plan to add on, build or run a business from home.
The homestead exemption
If a home is your main residence, you can apply for a homestead exemption with your county appraisal district.
It lowers the taxable value of the home, which lowers your property tax bill. You apply once you own the home and live in it; check your appraisal district for deadlines.
Why taxes on a brand-new home can jump
Property taxes are based on the value the county appraisal district sets as of January 1.
If a new home was finished during the year, the last tax bill may only reflect the land or a partly built house. The next bill is usually based on the finished home, so it can be much higher. Budget for the full amount.
Option period and earnest money
In a typical Texas home purchase, the buyer pays an option fee for a short option period, usually used for inspections. During that time, the buyer can end the contract for any reason, but the option fee usually isn't refunded. If the purchase closes, it's usually credited toward the price (the contract says whether).
Earnest money is a deposit held by the title company and applied at closing. The exact terms depend on your contract, and I'll walk you through them.
Flood zone vs. flood history
A flood zone is FEMA's map estimate of risk for an area. Flood history is whether this specific home has actually flooded.
A home can be outside a high-risk zone and still have flooded, so it's worth asking about both.
