Understanding property tax liens and their priority

Unpaid property taxes typically create a lien against the property. This lien almost always takes priority over other liens, such as mortgages or judgments. This means that when the property sells, these back taxes usually must be paid off first from the sale proceeds.

Ignoring these liens can lead to significant financial headaches, as they remain with the property until satisfied. Your due diligence must include a thorough check for any outstanding tax obligations before you finalize your offer.

Locating and verifying outstanding tax amounts

The most reliable place to find information on outstanding property taxes is your local county tax assessor’s or collector’s office. Many counties provide this information online through their property search portals. You will usually need the property address or parcel number.

Look for any delinquent tax records, including the original amount, penalties, and interest. Do not rely solely on what the seller tells you, as he or she may not have the most current or complete information. Verify all figures directly with the county.

Calculating the total amount due, including penalties and interest

Property tax arrears can quickly accumulate interest and penalties, especially if they have been outstanding for a while. When you pull the records, ensure you get the most up-to-date payoff amount, or at least understand how the interest and penalties are calculated daily. This can be more complex than just the principal amount.

Your calculation for the total tax burden must be precise. Suppose a property has $5,000 in back taxes. With hypothetical penalties and interest, that figure could easily climb to $6,000 or more by the time you close. This total amount needs to be deducted from your maximum allowable offer.

Adjusting your offer to account for the tax burden

The total amount of outstanding property taxes, including all penalties and interest, effectively reduces the net proceeds the seller receives. Therefore, this amount must be factored into your offer calculation. It comes directly out of what you can pay for the property.

If your maximum offer for a property, based on your ARV and the 70% rule, is hypothetical $100,000, and there are $5,000 in back taxes, your new effective offer ceiling for the seller’s equity is $95,000. This is a direct reduction of your buying power. For more on how to calculate your offer, see /learn/arv-and-70-percent-rule.

Communicating the tax implications to the seller

When you present your offer, clearly explain how the outstanding taxes affect the purchase price. Do not assume the seller understands that these amounts will be paid out of his or her sale proceeds. Be empathetic but firm.

You can say, "Mr./Mrs. Seller, our research shows there's an outstanding property tax balance of approximately $X. This amount will need to be paid at closing, and it's reflected in the offer we are able to make." This clarity prevents misunderstandings at the closing table. Remember, this is not legal or tax advice; always advise the seller to consult with his or her own professionals.

Considering the closing process with tax liens

Your title company will identify all outstanding liens, including property tax liens, during their search. They will typically require these to be paid off at closing to provide clear title to you as the buyer. This ensures you acquire the property free of that particular encumbrance.

Work closely with your title company to confirm the exact payoff amounts and ensure they are handled correctly. Understanding the closing process, especially with encumbrances like tax liens, is vital to avoid last-minute delays or unexpected costs. Speed to Seller focuses on connecting you with motivated sellers; dealing with these property details is your next step in underwriting.

Questions people ask

Where do I find information on back taxes for a property?

You can typically find this information through your local county tax assessor's or collector's office, often available on their official website by searching the property address or parcel number.

Can the seller negotiate the back tax amount?

No, property tax amounts are set by the taxing authority and usually cannot be negotiated by the seller or buyer. They must be paid in full to clear the lien.

Does a tax lien affect the property's clear title?

Yes, an unpaid property tax lien creates an encumbrance on the title, meaning the property cannot be sold with clear title until the lien is satisfied. This is why it is paid at closing.

Is it always my responsibility to pay the back taxes as the buyer?

No, it is typically the seller's responsibility to deliver clear title. However, as the buyer, you will factor the amount of the lien into your offer, and the taxes will be paid out of the sale proceeds at closing. This is not legal or tax advice.
