How rising property taxes affect cash offer calculations

Rising property taxes directly impact your cash offer calculations because they increase the holding costs and future expenses for a buyer or end-user. This change reduces the net profit potential, often requiring an adjustment to your maximum allowable offer.

Why property taxes are critical for investors

Property taxes are a non-negotiable expense that affects every real estate deal, whether you are wholesaling, flipping, or holding a rental. These taxes are part of the carrying costs during your ownership period and a recurring expense for any subsequent buyer. Ignoring them means miscalculating your potential profit and your buyer's burden.

For a wholesale deal, higher property taxes make the property less attractive to your cash buyers, as it eats into their margins or reduces his or her rental yield. For a flip, they increase the holding costs during the renovation phase. Always account for them in your initial analysis.

Calculating holding costs with higher property taxes

To calculate holding costs, factor in the new, higher property tax amount on a monthly basis. Add this to your insurance, utilities, and any other regular expenses. This sum represents what it costs you or your buyer to own the property each month it is not generating income or sold.

Suppose you typically hold a flip for six months. If property taxes increase by $100 per month, that is an extra $600 directly out of your profit. This is a simple illustration; actual costs will vary. These incremental costs accumulate quickly and must be part of your financial model.

Impact on a future buyer's affordability and interest

Higher property taxes make a property more expensive for the end buyer, whether he or she is a primary resident or a landlord. For owner-occupants, it increases their monthly housing expense. For investors, it reduces his or her net operating income and return on investment.

This impacts the pool of potential buyers and the price he or she is willing to pay. In some cases, a significant tax increase can push a property out of an ideal price range for a target demographic, making it harder to sell quickly or at your target ARV.

Adjusting your maximum allowable offer for tax increases

Your maximum allowable offer (MAO) formula needs to reflect increased property taxes. Since the MAO is often derived from the after-repair value (ARV) minus all costs and desired profit, any increase in costs, like taxes, directly reduces your MAO.

Before making an offer, verify the current property tax assessment and any recent changes. Look for pending re-assessments or new tax rates in the county or municipality. Build a buffer into your calculations, especially in areas with frequent tax adjustments, to protect your margin.

Where to find recent property tax assessment changes

The best place to find current and historical property tax information is usually the county assessor's or tax collector's website. These sites often provide detailed assessment histories, tax rates, and projected values. Public records are your primary source for this data.

You can also check with a local title company or real estate agent who is familiar with the area. He or she might have insights into upcoming tax changes or common assessment practices in that specific jurisdiction. Always cross-reference information from multiple sources if possible.

Questions people ask

Do higher property taxes only matter for long-term holds?

No, higher property taxes matter for all types of deals. Even for a short-term flip or wholesale, they contribute to your holding costs or make the property less attractive to your cash buyer, affecting your MAO and ultimately your profit.

How quickly can property taxes change?

Property taxes can change annually, especially after re-assessments or if a local government adjusts its millage rates. Always check the current year's assessment and look for any recent sales data that might trigger a re-assessment.

Should I include property taxes in my repair budget?

Property taxes are usually categorized under holding costs, not repair costs. Keep them separate in your budget for clarity. Repair costs are for physical improvements, while property taxes are ongoing ownership expenses.
