How to Find Out If a House Is a Rental Property

How to find out if a house is a rental: check the tax mailing address, homestead exemption, owner name and city rental registry in free public records.

Maybe you are thinking about buying the house next door, checking on a neighborhood before you move, wondering why the lawn across the street is never mowed, or trying to reach a landlord about a shared fence. Whatever the reason, you can often tell whether a house is owner-occupied or rented without knocking on a single door. County and city records leave a trail of clues. This guide explains how to find out if a house is a rental using free public records, what each clue really means, and where the records can mislead you. Office names and online tools vary from place to place, so check what your county and city offer.

Step 1: Pull up the parcel record

  1. Find the parcel. Pick the state and county on the Platbookmapper land map and open the county GIS or parcel viewer. Search by street address, or click the lot on the map. Our guide on how to use a county GIS viewer walks through the basics.
  2. Open the assessor or tax record. Most viewers link from the parcel to the assessor's property card or the treasurer's tax page. That is where most of the rental clues below live.
  3. Write down the parcel number. It is the most reliable way to find the same property in the tax, deed, permit and code enforcement systems.

Clue 1: The tax mailing address is somewhere else

Every tax record shows where the bill is sent. If the tax mailing address is the house itself, the owner probably lives there. If the bill goes to a different street, another town, another state or a P.O. box, the owner may live elsewhere and rent the house out.

This is a strong hint but not proof. Bills also go to lenders, accountants, relatives, second homes and people who simply prefer a P.O. box. Our guide on how to read a property tax bill shows where the owner and mailing lines usually appear, and looking up property taxes by address explains how to find the bill online.

Clue 2: No homestead exemption

Most states give owners a property tax break on their main home, often called a homestead exemption (Michigan calls its version a principal residence exemption). Owners usually have to apply and live in the home to qualify, so a rental house normally does not carry one.

Clue 3: The property class or use code

Assessors sort parcels into classes or land use codes, and some jurisdictions tax owner-occupied homes and other residential property differently. A code meaning something like “residential, non-homestead,” “rental,” or “multi-family” on the property card is a useful hint. Codes are local, so look for a legend or code list on the assessor's website before you read too much into one.

Clue 4: Who the owner is

Read the owner of record closely. Our guide to what an owner of record is explains the basics.

Owner shown asWhat it may suggest
An LLC, corporation or partnershipOften an investor or landlord, though some families hold their own home in an LLC.
A trustUsually estate planning, which is common for owner-occupied homes. Not a rental clue by itself.
A name that owns many parcelsSearching the owner's name in the parcel viewer can show whether the same person or company holds several houses. Our guide on finding a parcel by owner name shows how.
A bank or government agencyThe house may be in foreclosure, bank-owned or public housing.

Clue 5: City rental registration or licensing

Many cities, and some counties and townships, require landlords to register rental units, get a rental license, or pass periodic inspections. Where that is the rule, the list of registered rentals is often public.

Not every place has a program, and not every landlord registers, so a missing listing does not prove the home is owner-occupied.

Clue 6: Permits, code cases and listings

Tips and cautions

How to find out if a house is a rental: FAQ

How can I tell if a house is a rental for free?

Open the county parcel viewer and the assessor or tax record for the address. A tax mailing address somewhere else, no homestead exemption and an LLC or company owner all point toward a rental.

Does a missing homestead exemption mean a house is rented?

Not on its own. It can also mean a second home, a vacant house, a recent sale, or an owner who never applied. It is a stronger clue when the tax bill also goes to a different address.

Is there a public list of rental properties?

In some places, yes. Many cities require landlords to register or license rental units, and some offer an online lookup by address. Search the city website for rental registration or rental license.

How do I find out who the landlord of a house is?

The owner of record on the county parcel or tax record is usually the landlord or the landlord's company. If the owner is an LLC, the state business entity search lists its registered agent.

Can I find out if a house is rented or owned by the address?

Usually. Look up the address on the county parcel map, then compare the property address with the tax mailing address and check for a homestead or principal residence exemption.

Is it legal to look up whether a house is a rental?

Yes. Property tax, assessor and rental registration records are generally public. Use them respectfully, do not trespass, and follow any rules that apply if you use the information for business.
